Description

E2670 series is a new line of flameproof detectors and transmitters intended for use in ATEX Zones 2 and 22.

E2670 series devices are based on PluraSens® multifunctional platform.

Combustible gas detector-transmitter E2670-LEL is intended to detect hydrogen, methane, acetylene, propane and butane.

The instrument utilises fully calibrated metal-oxide semiconductor or pellistor gas sensors 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.
