Description

Combustible gas detector-transmitter E2648-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 areas, 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. Catalytic (pellistor) sensor is available as an option (except for acetylene detection).

To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommend to set the output scale within 20-100% of the detection range.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. Default alarm setpoints are 20% LEL and 50% LEL.

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