Methane Detector-Transmitter

  • Easy to install robust enclosure
  • Range 0...100% LEL (0...5 %vol) CH4
  • Two analog outputs settable to 4-20 mA or 0-10 V
  • RS485 Modbus RTU digital interface
  • Relay option
  • Remote probe option


Methane detector-transmitter E2648-CH4 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include underground parkings, boiler houses, kitchens, and other areas, where potentially explosive concentration of methane can accumulate.

The instrument utilises novel fully calibrated and temperature compensated MOS gas sensor with excellent repeatability, stability and long lifetime. Catalytic (pellistor) sensor is available as an option.

To connect the detector-transmitter to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommnd to set the difference between the upper and bottom limits of the output scale not narrower than 20% of detection range.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. By default, the alarm set-points are user set at 20% LEL and 50% LEL.

The device is available with either attached or remote sensor probe (default cable length is 3 m).
