Exchangeable sensor including digital value processing, temperature compensation and self control for the continuous monitoring of the ambient air.

Gas detection system

Gas detection sensors

Product Description

The sensor cartridge SC2 includes an electrochemical sensor element and an amplifier as well as a μController for measured values processing. All relevant data and measured values of the sensor element are stored fail-safe in the μController and transmitted digitally via the local bus to the sensor board SB2 or MSB2. The calibration management is also integrated in the μController of the sensor cartridge.
Calibration is done either by simply replacing the sensor cartridge or by using the comfortable, integrated calibration routine directly at the system.
The PolyGard®2 Sensor Cartridge is used for the detection of toxic gases and oxygen.
