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.

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. WeatherHawk systems are also available with an optional MODBUS protocol for use in industrial control applications and other applications where necessary.
