Combustible Gases Detector-Transmitter

  • Long-life metal-oxide gas sensor
  • Range 0...100 %LEL
  • Resolution 0,2 %LEL
  • Default alarm set-points 20 %LEL / 50 %LEL
  • 2 × 4-20 mA / 0-10 V, RS485


Combustible gases detector+transmitter E2611-LEL is a member of new PluraSens® family of multifunctional measurement instruments. The transmitter exhibits sensitivity to hydrogen, methane, acetylene, propane and butane.

Applications include underground parkings, boiler houses, kitchens, battery charging rooms and other spaces, where potentially explosive concentration of combustible gases can accumulate. 

The instrument utilises novel fully calibrated and temperature compensated metal-oxide gas sensor with excellent repeatability, stability and long lifetime. 

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

Two relays with closing contact may be used for remote signalling or ventilation control. Also the internal buzzer gives sound alarms at two set-points. Default alarm set-points are typically at 20 %LEL and at 50 %LEL.
