IR22-808-D IR 22 Fixed Transmitter with Carbon Dioxide (CO2) Sensor, 0 - 25% vol. or 0 - 50% vol. Range, Display / 4-20 mA by GfG

The IR 22 transmitter combines the proven infrared measurement method to detect carbon dioxide or combustible gases (HC) with the innovative technique of the new 22 series transmitters. This new GfG transmit- ter generation has been developed and manufactured according to SIL standards.

The comprehensive user menu and the versatile setting options make this transmitter series quite flexible and adaptable to all individual requirements. Precise measurement results at various environmental conditions, as well as the large dynamic measurement range of a few ppm up to 5 % volume CO2 or 100% LEL.

Time-proven and innovative

The EC 22 is equipped with high quality GfG sensors. The transmitters are fitted with high-performance electronics for voltage stabilization, processing of readings, and temperature compensation. Follow up costs are minimized thanks to the long lifespan of the sensors.

Signal processing

The transmitter includes the complete electronic system for the signal processing and fail-safe forwarding of the measurement signal to the controller. The embedded software of the IR 22 linearises the measurement signal and compensates for environmental influences.

Therefore, when temperature variations are caused by the weather or changes of the humidity, the measured values will be accurate.

In addition, the transmitter provides the option to transfer service, maintenance and error messages to a connected GfG gas measurement controller. The IR 22 transmitter sends the signals either through an analog 4-20 mA current interface or a digital (RS485) Modbus interface.

Flexibility for any application

The IR 22 transmitter includes the sensor, status LEDs, either an analog or a digital interface, "Zero button" to adjust the zero point, and a test socket and potentiometer for the sensor calibration.

In addition, the IR 22 can be ordered with backlit graphical display. The display shows the current gas concentration, allows access to service functions, enables operation using a membrane keypad and includes optical and acoustical signal transmitters.
