BW Technologies Dummy Sensor for 3-Pin O2 or 3-Pin Twin Tox Locations

The BW Technologies Dummy Sensor for 3-Pin O2 or 3-Pin Twin Tox Locations is a dummy sensor that acts as a placeholder for the device. This dummy sensor does not detect gases and does not initiate the alarm sequence on the device. The sensor can be used for training and storage purposes. This cost effective dummy sensor fits several BW Technologies products.

4400-3 4000 Series Integrated Controller, 12 Channels, 10 Amp Power Supply by GfG

The 4100 one-channel and the 4-channel 4400 gas warning systems offer safe and reliable gas detection

Alarm points

Each alarm can be adjusted separately. False alarms are eliminated with the adjustable alarm delay. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be selected to be latching / non-latching or resettable / non resettable.

Alarm relays

The controller provides four voltage-free relays for the three alarms in addition to one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.

Additional features

The 4100 control panel stores peak values and offers an additional 4-20 mA output. The 4400 control panel offers the ability to connect up to 4 transmitters and comes standard with an additional 24 VAC output for solenoid control.

Features

• Complete 1-to-4 channel controller / gas monitoring system
• 110 VAC or 24 VAC
• Case-mounted horn / strobe
• Security lock
• Slim-line design

2901-50-005 IR 29 Di Gas Transmitter with Display, with Pressure and Humidity Compensation, IP67, Carbon Dioxide (CO₂), 0 - 5% vol. Range by GfG

Measuring Principle

IR transmitters have become recognized as reliable gas warning systems for explosion protection. They are used to detect individual combustible gases or a wide range of gases. This involves sending an IR beam with a certain light intensity through a measuring space and then capturing it with a detector. Parts of this beam are absorbed by, amongst other things, hydrocarbon molecules. The reduced light intensity of the beam is registered by beam detectors and converted into a signal as the existing % LEL gas concentration.

Benefits

A special feature of our IR technology is its ability to also measure combustible gases above the lower explosion limit. Moreover, the measurement does not require oxygen.

With this technology there is basically no risk of contaminating the sensor, through silicone vapors or hydrogen sulfide, when using catalytic combustion sensors.

Operation

IR transmitters are usually used with 2 wavelengths, a so-called reference wavelength and just one measuring wavelength. Strict limits are applied to these systems. The absorption spectra of many hydrocarbons are located in the wavelength range of 3.3 μm and overlap to a large extent.

This means that gases with overlapping spectra and just one measuring wavelength can no longer be clearly distinguished. Some hydrocarbons, e.g. the frequently used welding gas acetylene, are non-absorbing in the wavelength range of 3.3 μm, but absorb instead in neighboring wavelength ranges.

In many practical applications, it is not essentially important which gas is responsible for the explosion risk. Therefore, early warnings through the broadband measurement of hydrocarbons in order to monitor the lower explosion limit (LEL) must be guaranteed. False alarms with uncritical concentrations of individual gases or solvents are thus absolutely unacceptable.

These requirements are problems for systems with 2 wavelengths.

Patented GfG Technology

The internationally patented technology of the IR 29 has been developed to solve these problems. The gold-plated mirror optics of the sensor contains 2 radiators and up to 4 detector elements with different optical filters. The precisely calculated, microstructured and pure gold coated mirror optics of the IR 29 are supplied for the first time without beam splitters.

This helps to cut signal losses by 50 % and to completely avoid the physically-related disadvantages of a beam splitter. The measured values from two additional wavelengths (4 wavelengths in total) ensure improved detection of individual gases and thus enhanced selectivity. This results in the prevention of false alarms. Only a 4 wavelength system always guarantees early warnings and the simultaneous prevention of false alarms.

New Technology

The IR 29 is the first and only intrinsically safe IR gas transmitter with patented 4-beam 4-wavelength technology.

The ignition protection class "intrinsically safe", which is so essential for industrial plants and the mining industry, is achieved by the additional use of the SB1 safety barrier and its internationally patented and innovative design.

Complete Safety Even In Zone 0

The IR 29 is the first IR gas transmitter that can also be used in Ex zone 0 and which enables maintenance as well as replacement of the sensor head without additional expense when energized.

Universal Application

The IR 29 with its robust V4A stainless steel housing has been designed to withstand the harshest environmental conditions.

The application areas of the dust and water-protected structure range from production and storage areas to disposal sites, biogas plants, mines and oil rigs.

Internal Data Logger

A standard built-in data logger records all the measuring data, minimum / maximum values, average values and alarm events of the last 24 hours in a ring buffer.

The recording can also be shown on the display as a 2 and 8 hour trend indicator.

The histogram mode can be selected as a permanent display of the measured values. These values are continuously updated.

Graphical Display

Measured values are shown on the high-contrast graphical display. The display can be rotated 180° depending on the installation of the IR 29.

Self Diagnosis

Processor-based signal processing enables the systematic compensation of temperature dependencies, aging influences and soiling effects. Safety-relevant functions are monitored permanently via self-diagnosis procedures and a possibly required service is indicated automatically. Daily interfering factors, such as dust and dirt accumulation, are almost completely eliminated by the innovative design.

Pressure Sensor, Moisture and Temperature Compensation

The measuring accuracy of IR sensors depends on partial pressure and thus also air pressure. Climatic fluctuations or barometric high pressure therefore influence the measuring result. Furthermore, the absorption spectrum of water almost completely covers that of hydrocarbon absorption in the 2.7 to 3.3 μm range. Air humidity therefore initially generates a measuring signal the same as the actual measuring gas. This cross-sensitivity is of particular importance in warm areas with high relative humidity. An increase in the absolute water absorption capacity of air is not linear with the temperature, i.e. three times as much water can be absorbed at 40 °C than at 20 °C. This influence can only be compensated if the current moisture content of the air is known. The IR 29 can be optionally equipped with a pressure and moisture sensor for compensation.

Maximum Safety

The innovative display enables the realization of completely safe warning concepts.

Local displays and signals directly at the device can be used to provide an early warning of potential risks.

The display at the upstream safety barrier SB1 D enables the detection of risks outside the danger zone being monitored.

This allows immediate on-site action before really hazardous situations occur.

Dust Protection

A gas permeable, water-repellent diaphragm protects the absorption space of the transmitter against dust. The additional impact protection made from robust V4A stainless steel prevents mechanical damage to the optical components.

The diaphragm can be cleaned or replaced in a matter of minutes.

Remote Controls

The IR 29 transmitter does not feature control elements for setting or servicing tasks. This helps to prevent accidental or unauthorized manipulation.

Service work at the IR 29 transmitter is carried out using the RC 2 remote control.
