MSR Germany Polygard Sensor for combustible gases in Hazardous zone 1&2

Gas Alarm Systems(www.gasalarmSystem.com.au) Australia in association with Gas alarm systems India (www.gasalarmsystems.in) are  pleased to introduce MSR Germany, Polygard  sensor for oil/gas or other hazardous industry. .

The PolyXeta®2 sensor is used in industrial areas like oil/gas industry, biogas plants, petrochemical industry, power plants etc. in Ex-Zone 2. The PolyXeta®2 sensor is also suitable for commercial areas like gas transfer stations etc. With the 4 – 20 mA / RS485-ModBus output signal the sensor is suitable for connection to the PolyGard®2 gas controller series by MSR-Electronic, as well as to any other controller or automation devices. Optionally, the PolyXeta®2 sensor is also available with LCD display and relay output

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 outside by a permanent magnet without opening the housing. In case of an alarm or fault the backlight of sensors with LCD display changes from green to red.
