Transmitter CC22

Detection of combustible gases

Superior technology

The CC22 works according to the heat tone principle, a proven method for measuring combustible gases. 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 service life of the sensors.

Signal processing

The embedded software of the CC22 linearises the measuring signal and compensates for the temperature impacts. As a result, correct readings are transmitted even with weather-related variations in temperature. In addition, the transmitter can be connected to a gas measurement computer for transmitting service, maintenance and error messages.

For transmitting the signals, the CC22 either uses an analogue (0.2 .. 1 mA / 4 .. 20 mA) or a digital (RS485) interface. This permits the universal use of the transmitters in combination with gas measurement computers of GfG and thus with your safety system such that you and your systems will benefit from the best possible protection.
