Methane Detector-Transmitter

  • Stable long-life metal-oxide gas sensor
  • Range 0...100% LEL (0...5 %vol) CH4
  • Resolution 0,1 %LEL (50 ppm) CH4
  • Attached or remote sensor options
  • 2 × 4-20 mA / 0-10 V, RS485
  • Two SPST relays


Methane detector-transmitter E2638R-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.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the device to safety or building automation systems.

Two relays with closing contact may be used for remote signaling or ventilation control. The default alarm set-points are typically at 20 and 50% LEL. The flashing LEDs and an internal buzzer (option) give alarms as well at two set-points.
