Description

E2658 series is a new line of flameproof detectors and transmitters intended for use in ATEX Zones 2 and 22. 

E2658 series devices are based on PluraSens® multifunctional platform.

Combustible gas detector-transmitter E2658-LEL is intended to detect hydrogen, methane, acetylene, propane and butane.

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.
