WeatherHawk, Test and Measurement

29302 621 Wireless Heated Weather Station by WeatherHawk

The WeatherHawk Series 600 family of weather stations measure and record wind speed and direction; air temperature and relative humidity; barometric pressure and solar radiation; rainfall and snowfall. In addition, the system calculates and exports an evapotranspiration (ET) value that can be used by third party systems for irrigation control. Series 600 weather stations are designed for applications where a minimal visual impact, high reliability, and a long interval between routine servicing are significant factors in the decision to purchase. The standard Series 600 system incorporates an integral 3 AHr battery pack, which is continually recharged by an external primary power source. Model 620 and 610 systems can be interfaced with an optional solar panel, while Model 621 and 611 systems require an AC power converter. All Series 600 weather stations are suitable for applications requiring high reliability.

The Series 600 family is fully compatible with most versions of software, data management, input power and mounting accessories designed for the WeatherHawk Signature and 500 Series weather stations.

The Series 600 WeatherHawk systems utilize solid state sensors, with no moving parts. Solid state sensors enable a low profile design better suited to high visibility locations where a traditional weather station would be visually objectionable; they have higher reliability and a longer interval between routine service and inspection requirements; they are more robust and less susceptible to damage from wind carried debris; and they are not compromised by heavy snowfall or freezing conditions that produce rime ice (NOTE: Heated sensor versions, Models 611/621, must be used in snow or freeze zone applications).

Models 610/611

These versions of the Series 600 weather station are directly connected to a host device (PC or server) through an RS232 serial data I/O located on the bottom of the weather station. The Model 611 incorporates a thermostatically controlled heater element in the sensor head that keeps the ultrasonic wind sensor elements and the radar precipitation sensor surface free of snow and ice to 50°C.

Models 620/621

These versions of the Series 600 weather station are wireless to a host device (PC or server) using fully integrated industrial grade 916 MHz spread spectrum RF communications technology. They also have an RS232 serial data I/O located on the bottom of the weather station, which can be used as a second serial communications port, or for programming and testing the system, or for direct data downloads using a PC or PDA. The Model 621 also incorporates a thermostatically controlled heater element in the sensor head that keeps the ultrasonic wind sensor elements and the radar precipitation sensor surface free of snow and ice to 50°C. Optional configurations of both units enable replacement of the 916 MHz RF components with 922 MHz and 2.4 GHz RF components to comply with local, regional or national radio frequency licensing requirements.

Sensor Technologies

Series 600 WeatherHawk weather stations employ the latest in weather measurement sensors. Wind speed and direction use acoustic techniques formerly available on only the most expensive professional wind velocity measurement systems. Precipitation is measured using a 24 GHz radar which can distinguish between rain and snow fall based on drop size and fall velocity. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by calibrated scientific grade sensors typically installed in the finest professional weather measurement and monitoring systems.

Wind Speed & Direction is measured by a sensor consisting of four ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.

Rainfall and Snowfall is measured using radar technology. The precipitation sensor works with a 24 GHz Doppler radar which measures the drop speed, and calculates precipitation quantity and type by correlating drop size and speed.

Air temperature is measured by a highly accurate NTC-resistor. The resistance value of this sensor changes in accordance with temperature thus providing an accurate temperature measurement.

Relative humidity is measured by a capacitive humidity sensor. Both the temperature and relative humidity sensor are housed in an aspirated radiation shield to prevent direct exposure to solar radiation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every three years, depending on the application.

Sensor Technologies

Series 500 WeatherHawk weather stations employ the latest in weather measurement sensors. Wind speed and direction use acoustic techniques formerly available on only the most expensive professional wind velocity measurement systems. Rain is measured using an impact surface that literally counts the raindrops and measures their acoustic signature, integrating that information to provide a near real-time value for rainfall amount and rate. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by calibrated scientific grade sensors typically installed in the finest professional weather measurement and monitoring systems.

Wind Speed & Direction is measured by a sensor consisting of three equally spaced ultrasonic transducers in a horizontal plane. The sensor measures the bi-directional transit time along the three paths established by the transducer array. This transit time is dependent on the wind velocity across the ultrasonic path. For zero wind velocity, both the forward and reverse transit times are identical; with wind, the upwind transit time increases and the downwind time decreases. The values of any two array paths will enable computation of both wind speed and direction, and a signal processing technique enables the measurement to be calculated using the two array paths of the best quality. If the system is used in a high accuracy application a factory revalidation is recommended every five years.

Rainfall is measured with a stainless steel piezometric surface on top of the weather station. As individual raindrops (or hailstones) impact on the surface they each provide an acoustic signature that is measured and processed in real-time to give a value for their volume. The volume is then processed with respect to time to provide a rainfall rate. This measurement technique eliminates all of the traditional problems with tipping bucket type rainfall measurement devices, including worn or damaged bearings, clogged funnels and drip orifices, and damage from wind blown debris.

Air temperature and relative humidity (RH) sensors are combined in an integrated, user replaceable unit that requires no calibration. The RH sensor is a thin polymer, capacitive type sensor that degrades with exposure due to age and airborne contaminates. It should be user replaced every three years to maintain accuracy, and at a shorter interval if the location is subject to high levels of air pollution or is subject to airborne chemical spraying. The air temperature sensor is a capacitive ceramic sensor that is typically not subject to environmental degradation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every 3-5 years, depending on the application.

16762 232 Direct Connect Weather Station by WeatherHawk

The WeatherHawk Signature Series family of weather stations measure and record wind speed and direction, air temperature and relative humidity, barometric pressure, solar radiation, and rain. In addition, the system calculates and exports an evapotranspiration (ET) value that can be used by third party systems for irrigation control. They are designed for applications where a visual impact is not a concern; and high reliability is significant factors in the decision to purchase.

The Signature Series family is fully compatible with all versions of software, data management, input power and mounting accessories designed for the WeatherHawk Series 500 family. It is also compatible with all third party certified software drivers.

The principle difference between the Signature Series and Series 500 WeatherHawk systems is that the Signature Series utilizes conventional, lower cost sensors, resulting in a lower system price. All WeatherHawk systems are industrial grade products, and they are easy to install, feature high reliability, and can be user serviced or repaired with replacement components that do not require field calibration, specialized tools or training.

Model 232

This version of the Signature Series weather station is directly connected to a host device (PC or server) through an RS232 serial data I/O located on the bottom of the weather station.

Models 916/922/240

These versions of the Signature Series weather station are wireless to a host device (PC or server) using fully integrated industrial grade MHz spread spectrum RF communications technology. The various model numbers reflect the center frequency of the radio, and the various frequencies are specifically licensed for use in various countries. All frequencies are licensed within the Americas, with the 916 (916 MHz) being preferred due to its greater range; the 240 (2.4 GHz) systems are generally acceptable worldwide; and the 916 (916 MHz) is licensed for use in Australia and New Zealand. The Signature Series wireless systems also have an RS232 serial data I/O located on the bottom of the weather station, which can be used as a second serial communications port, or for programming and testing the system, or for direct data downloads using a PC or PDA.

Various external antenna configurations are available for these wirless systems that can extend their LOS (line of sight) range from 1/2 mile for 900 MHz systems, to over 7 miles; and from 1/4 mile for 2.4 GHz systems to over 3 miles.

Sensor Technologies

Signature Series WeatherHawk weather stations employ well proven weather measurement sensors. Wind speed and direction use rotating anemometer and vane devices commonly used on professional wind velocity measurement systems. Rain is measured using a volumetric tipping bucket, self-draining rain gauge for rainfall. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by a combination of industrial and scientific grade sensors.

Wind Speed is measured by a three cup rotating anemometer. The rotating component of the sensor spins in response to the wind and turns a magnet within a coil to generate a sine wave output proportional to velocity. This technique is well proven and reliable under normal conditions, but the rotating component can lock up in freezing or icy conditions.

Wind Direction is measured by a sensor consisting of a vane connected to a wire wound resistor. As the vane turns on its pivot point the resistance increases or decreases with respect to wind direction. This is translated by the weather station into a measurement in degrees with respect to a datum, typically magnetic North, which is physically established when the weather station is installed.

Rainfall is measured with a tipping bucket rain gauge. During a rain event drops are captured in a funnel of a know size and directed through an orifice to form a drip stream. This drip stream flows into a volumetric measurement device (a tipping bucket or spoon), which fills with a calibrated amount and then tips. The tipping motion dumps the water and activates a switch which produces an electrical pulse. The water then drains from the bttom of the rain gauge and the mechanism returns to its catch location to fill again. The pulses are counted by the weather station and multiplied by the known volume of the tipping bucket to produce a rainfall amount, and when compared to time, a rainfall rate.

Air temperature and relative humidity (RH) sensors are combined in an integrated,user replaceable unit that requires no calibration. The RH sensor is a thin polymer, resistive sensor that degrades with exposure due to age and airborne contaminates. It should be user replaced every 18-24 months to maintain accuracy, and at a shorter interval if the location is subject to high levels of air pollution or is subject to airborne chemical spraying. The air temperature sensor is a fine wire thermistor, with a rapid response, and it is typically not subject to environmental degradation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a scientific grade silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every 3-5 years, depending on the application.

29303 620 Wireless Weather Station by WeatherHawk

The WeatherHawk Series 600 family of weather stations measure and record wind speed and direction; air temperature and relative humidity; barometric pressure and solar radiation; rainfall and snowfall. In addition, the system calculates and exports an evapotranspiration (ET) value that can be used by third party systems for irrigation control. Series 600 weather stations are designed for applications where a minimal visual impact, high reliability, and a long interval between routine servicing are significant factors in the decision to purchase. The standard Series 600 system incorporates an integral 3 AHr battery pack, which is continually recharged by an external primary power source. Model 620 and 610 systems can be interfaced with an optional solar panel, while Model 621 and 611 systems require an AC power converter. All Series 600 weather stations are suitable for applications requiring high reliability.

The Series 600 family is fully compatible with most versions of software, data management, input power and mounting accessories designed for the WeatherHawk Signature and 500 Series weather stations.

The Series 600 WeatherHawk systems utilize solid state sensors, with no moving parts. Solid state sensors enable a low profile design better suited to high visibility locations where a traditional weather station would be visually objectionable; they have higher reliability and a longer interval between routine service and inspection requirements; they are more robust and less susceptible to damage from wind carried debris; and they are not compromised by heavy snowfall or freezing conditions that produce rime ice (NOTE: Heated sensor versions, Models 611/621, must be used in snow or freeze zone applications).

Models 610/611

These versions of the Series 600 weather station are directly connected to a host device (PC or server) through an RS232 serial data I/O located on the bottom of the weather station. The Model 611 incorporates a thermostatically controlled heater element in the sensor head that keeps the ultrasonic wind sensor elements and the radar precipitation sensor surface free of snow and ice to 50°C.

Models 620/621

These versions of the Series 600 weather station are wireless to a host device (PC or server) using fully integrated industrial grade 916 MHz spread spectrum RF communications technology. They also have an RS232 serial data I/O located on the bottom of the weather station, which can be used as a second serial communications port, or for programming and testing the system, or for direct data downloads using a PC or PDA. The Model 621 also incorporates a thermostatically controlled heater element in the sensor head that keeps the ultrasonic wind sensor elements and the radar precipitation sensor surface free of snow and ice to 50°C. Optional configurations of both units enable replacement of the 916 MHz RF components with 922 MHz and 2.4 GHz RF components to comply with local, regional or national radio frequency licensing requirements.

Sensor Technologies

Series 600 WeatherHawk weather stations employ the latest in weather measurement sensors. Wind speed and direction use acoustic techniques formerly available on only the most expensive professional wind velocity measurement systems. Precipitation is measured using a 24 GHz radar which can distinguish between rain and snow fall based on drop size and fall velocity. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by calibrated scientific grade sensors typically installed in the finest professional weather measurement and monitoring systems.

Wind Speed & Direction is measured by a sensor consisting of four ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.

Rainfall and Snowfall is measured using radar technology. The precipitation sensor works with a 24 GHz Doppler radar which measures the drop speed, and calculates precipitation quantity and type by correlating drop size and speed.

Air temperature is measured by a highly accurate NTC-resistor. The resistance value of this sensor changes in accordance with temperature thus providing an accurate temperature measurement.

Relative humidity is measured by a capacitive humidity sensor. Both the temperature and relative humidity sensor are housed in an aspirated radiation shield to prevent direct exposure to solar radiation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every three years, depending on the application.

Data Transfer Protocols, Software and Data Interface Hardware

All WeatherHawk systems communicate using a proprietary Pakbus protocol. Any qualified software developer may request a software development kit, at no charge, to assist in the development of software drivers for third party devices or software.

16008 916 Wireless Weather Station by WeatherHawk

The WeatherHawk Signature Series family of weather stations measure and record wind speed and direction, air temperature and relative humidity, barometric pressure, solar radiation, and rain. In addition, the system calculates and exports an evapotranspiration (ET) value that can be used by third party systems for irrigation control. They are designed for applications where a visual impact is not a concern; and high reliability is significant factors in the decision to purchase.

The Signature Series family is fully compatible with all versions of software, data management, input power and mounting accessories designed for the WeatherHawk Series 500 family. It is also compatible with all third party certified software drivers.

The principle difference between the Signature Series and Series 500 WeatherHawk systems is that the Signature Series utilizes conventional, lower cost sensors, resulting in a lower system price. All WeatherHawk systems are industrial grade products, and they are easy to install, feature high reliability, and can be user serviced or repaired with replacement components that do not require field calibration, specialized tools or training.

Model 232

This version of the Signature Series weather station is directly connected to a host device (PC or server) through an RS232 serial data I/O located on the bottom of the weather station.

Models 916/922/240

These versions of the Signature Series weather station are wireless to a host device (PC or server) using fully integrated industrial grade MHz spread spectrum RF communications technology. The various model numbers reflect the center frequency of the radio, and the various frequencies are specifically licensed for use in various countries. All frequencies are licensed within the Americas, with the 916 (916 MHz) being preferred due to its greater range; the 240 (2.4 GHz) systems are generally acceptable worldwide; and the 916 (916 MHz) is licensed for use in Australia and New Zealand. The Signature Series wireless systems also have an RS232 serial data I/O located on the bottom of the weather station, which can be used as a second serial communications port, or for programming and testing the system, or for direct data downloads using a PC or PDA.

Various external antenna configurations are available for these wirless systems that can extend their LOS (line of sight) range from 1/2 mile for 900 MHz systems, to over 7 miles; and from 1/4 mile for 2.4 GHz systems to over 3 miles.

Sensor Technologies

Signature Series WeatherHawk weather stations employ well proven weather measurement sensors. Wind speed and direction use rotating anemometer and vane devices commonly used on professional wind velocity measurement systems. Rain is measured using a volumetric tipping bucket, self-draining rain gauge for rainfall. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by a combination of industrial and scientific grade sensors.

Wind Speed is measured by a three cup rotating anemometer. The rotating component of the sensor spins in response to the wind and turns a magnet within a coil to generate a sine wave output proportional to velocity. This technique is well proven and reliable under normal conditions, but the rotating component can lock up in freezing or icy conditions.

Wind Direction is measured by a sensor consisting of a vane connected to a wire wound resistor. As the vane turns on its pivot point the resistance increases or decreases with respect to wind direction. This is translated by the weather station into a measurement in degrees with respect to a datum, typically magnetic North, which is physically established when the weather station is installed.

Rainfall is measured with a tipping bucket rain gauge. During a rain event drops are captured in a funnel of a know size and directed through an orifice to form a drip stream. This drip stream flows into a volumetric measurement device (a tipping bucket or spoon), which fills with a calibrated amount and then tips. The tipping motion dumps the water and activates a switch which produces an electrical pulse. The water then drains from the bttom of the rain gauge and the mechanism returns to its catch location to fill again. The pulses are counted by the weather station and multiplied by the known volume of the tipping bucket to produce a rainfall amount, and when compared to time, a rainfall rate.

Air temperature and relative humidity (RH) sensors are combined in an integrated,user replaceable unit that requires no calibration. The RH sensor is a thin polymer, resistive sensor that degrades with exposure due to age and airborne contaminates. It should be user replaced every 18-24 months to maintain accuracy, and at a shorter interval if the location is subject to high levels of air pollution or is subject to airborne chemical spraying. The air temperature sensor is a fine wire thermistor, with a rapid response, and it is typically not subject to environmental degradation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a scientific grade silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every 3-5 years, depending on the application.

29301 610 Direct Connect Weather Station by WeatherHawk

The WeatherHawk Series 600 family of weather stations measure and record wind speed and direction; air temperature and relative humidity; barometric pressure and solar radiation; rainfall and snowfall. In addition, the system calculates and exports an evapotranspiration (ET) value that can be used by third party systems for irrigation control. Series 600 weather stations are designed for applications where a minimal visual impact, high reliability, and a long interval between routine servicing are significant factors in the decision to purchase. The standard Series 600 system incorporates an integral 3 AHr battery pack, which is continually recharged by an external primary power source. Model 620 and 610 systems can be interfaced with an optional solar panel, while Model 621 and 611 systems require an AC power converter. All Series 600 weather stations are suitable for applications requiring high reliability.

The Series 600 family is fully compatible with most versions of software, data management, input power and mounting accessories designed for the WeatherHawk Signature and 500 Series weather stations.

The Series 600 WeatherHawk systems utilize solid state sensors, with no moving parts. Solid state sensors enable a low profile design better suited to high visibility locations where a traditional weather station would be visually objectionable; they have higher reliability and a longer interval between routine service and inspection requirements; they are more robust and less susceptible to damage from wind carried debris; and they are not compromised by heavy snowfall or freezing conditions that produce rime ice (NOTE: Heated sensor versions, Models 611/621, must be used in snow or freeze zone applications).

Models 610/611

These versions of the Series 600 weather station are directly connected to a host device (PC or server) through an RS232 serial data I/O located on the bottom of the weather station. The Model 611 incorporates a thermostatically controlled heater element in the sensor head that keeps the ultrasonic wind sensor elements and the radar precipitation sensor surface free of snow and ice to 50°C.

Models 620/621

These versions of the Series 600 weather station are wireless to a host device (PC or server) using fully integrated industrial grade 916 MHz spread spectrum RF communications technology. They also have an RS232 serial data I/O located on the bottom of the weather station, which can be used as a second serial communications port, or for programming and testing the system, or for direct data downloads using a PC or PDA. The Model 621 also incorporates a thermostatically controlled heater element in the sensor head that keeps the ultrasonic wind sensor elements and the radar precipitation sensor surface free of snow and ice to 50°C. Optional configurations of both units enable replacement of the 916 MHz RF components with 922 MHz and 2.4 GHz RF components to comply with local, regional or national radio frequency licensing requirements.

Sensor Technologies

Series 600 WeatherHawk weather stations employ the latest in weather measurement sensors. Wind speed and direction use acoustic techniques formerly available on only the most expensive professional wind velocity measurement systems. Precipitation is measured using a 24 GHz radar which can distinguish between rain and snow fall based on drop size and fall velocity. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by calibrated scientific grade sensors typically installed in the finest professional weather measurement and monitoring systems.

Wind Speed & Direction is measured by a sensor consisting of four ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.

Rainfall and Snowfall is measured using radar technology. The precipitation sensor works with a 24 GHz Doppler radar which measures the drop speed, and calculates precipitation quantity and type by correlating drop size and speed.

Air temperature is measured by a highly accurate NTC-resistor. The resistance value of this sensor changes in accordance with temperature thus providing an accurate temperature measurement.

Relative humidity is measured by a capacitive humidity sensor. Both the temperature and relative humidity sensor are housed in an aspirated radiation shield to prevent direct exposure to solar radiation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every three years, depending on the application.

Sensor Technologies

Series 500 WeatherHawk weather stations employ the latest in weather measurement sensors. Wind speed and direction use acoustic techniques formerly available on only the most expensive professional wind velocity measurement systems. Rain is measured using an impact surface that literally counts the raindrops and measures their acoustic signature, integrating that information to provide a near real-time value for rainfall amount and rate. Barometric pressure, relative humidity, air temperature and solar radiation measurements are made by calibrated scientific grade sensors typically installed in the finest professional weather measurement and monitoring systems.

Wind Speed & Direction is measured by a sensor consisting of three equally spaced ultrasonic transducers in a horizontal plane. The sensor measures the bi-directional transit time along the three paths established by the transducer array. This transit time is dependent on the wind velocity across the ultrasonic path. For zero wind velocity, both the forward and reverse transit times are identical; with wind, the upwind transit time increases and the downwind time decreases. The values of any two array paths will enable computation of both wind speed and direction, and a signal processing technique enables the measurement to be calculated using the two array paths of the best quality. If the system is used in a high accuracy application a factory revalidation is recommended every five years.

Rainfall is measured with a stainless steel piezometric surface on top of the weather station. As individual raindrops (or hailstones) impact on the surface they each provide an acoustic signature that is measured and processed in real-time to give a value for their volume. The volume is then processed with respect to time to provide a rainfall rate. This measurement technique eliminates all of the traditional problems with tipping bucket type rainfall measurement devices, including worn or damaged bearings, clogged funnels and drip orifices, and damage from wind blown debris.

Air temperature and relative humidity (RH) sensors are combined in an integrated, user replaceable unit that requires no calibration. The RH sensor is a thin polymer, capacitive type sensor that degrades with exposure due to age and airborne contaminates. It should be user replaced every three years to maintain accuracy, and at a shorter interval if the location is subject to high levels of air pollution or is subject to airborne chemical spraying. The air temperature sensor is a capacitive ceramic sensor that is typically not subject to environmental degradation.

Barometric pressure is measured with a capacitive silicon temperature corrected strain gauge device that is typically not degraded by environmental exposure and does not require calibration after manufacture.

Solar Radiation is measured by a silicon pyranometer with a cut filter limiting the spectral exposure to the 300-1100 nm wavelength. This device typically degrades at a rate of 2% of the full scale value each year and should be recalibrated, or replaced every 3-5 years, depending on the application.
