PolyXeta II:

Sensor series for combustible, toxic gases and O2 in Zone 1, Zone 2 and commercial applications


Microprocessor based gas sensor with 4 – 20 mA / RS 485 output signal for monitoring the ambient air and detecting flammable and vapours, toxic gases and oxygen with diffe t sensor elements. The gas sensor is available i the types ”Ex dem [ib]“ (also to be opened in

Zone 1 at any time) and “Ex d“ (only to be opened in the types ”Ex dem [ib]“ (also to be opened in Zone 1 at any time) and “Ex d“ (only to be opened in Zone 2 at any time).

The calibration for types without LCD display is possible via the handheld calibration device. The types with LCD display have a non intrusive magnetic calibration feature for easy calibration without opening the instrument and declassifying the area. At alarm or faulty of the sensor, the backlight of the LCD display changes from green to red.


  • ATEX and IEC Ex certifications MSR Electronic
  • Safety integration level 2 (SIL2)
  • Type “Ex dem[ib]“ to open in Zone 1 without switching off
  • Type “Ex d“ with flameproof enclosure
  • Continuous monitoring
  • Microprocessor with 12 bit converter resolution
  • Self diagnostic procedure
  • Watch dog switch
  • Easy calibration, opening of the housing during operation possible (dem [ib])
  • 4 to 20mA proportional output
  • Reverse polarity protected
  • Overload-proof
  • LCD display with status LED (optional), LCD Backlight green /red
  • Fauly relay (optional); LCD Backlight changes from green to red
  • Alarm relay (optional); LCD Backlight changes from green to red
