The sensor cartridge SC2 includes a high performance sensing element (electrochemical for toxic gases and pellistor type for combustible gases), and an amplifier as well as a microprocessor. All important data and measured values of the sensor element are stored fail-safe in the module and transmitted digitally via the local bus to the transmitter or controller. The calibration management is also integrated in the microprocessor of the sensor cartridge.

Calibration is done either by simply swapping the sensor cartridge or by using the user friendly, integrated calibration routine directly at the system.


• Digital measurement value processing including temperature compensation
• Internal diagnostics including integrated hardware watchdog
• Data / measured values in Sensor Cartridge, therefore simple exchange of SC uncalibrated <> calibrated
• High accuracy, selectivity and reliability
• Low zero point drift
• Sensor with long life expectancy
• Hardware & software according to SIL 2 compliant development process
• Modular technology (plug-in and replaceable)
• X-Change, easy maintenance and calibration by exchange of the sensor cartridge or by user friendly on-site calibration
• Reverse polarity protected, overload and shortcircuit proof
