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 a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime.
Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.
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.
