The PolyXeta 2 sensor is used in industrial areas like oil/gas industry, biogas plants, petrochemical industry, power plants etc in Ex-Zone 1 or Zone 2. The PolyXeta 2 sensor is also suitable for commercial areas like gas transfer stations etc

Microprocessor based gas sensor with 4 – 20 mA / RS485-Modbus output signal, alarm and fault relays (all SIL2 certified) for monitoring the ambient air to detect combustible gases and vapors within the lower explosive limit (LEL) by means of a catalytic sensor element (pellistor) or an infrared sensor element. The calibration of sensors without LCD display is carried out via the calibration device Cal PX or the PC software PC-Soft 80. Sensors with LCD display have an integrated calibration routine that is started from the outside by a permanent magnet without opening the housing. In case of an alarm or a fault, the backlight of the sensors with LCD display changes from green to red.
