Description

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

E2658 series devices are based on PluraSens® multifunctional platform.

Carbon dioxide transmitter E2658-COutilises a fully calibrated and temperature compensated photoacoustic gas sensor with excellent repeatability, stability and long lifetime. Ambient pressure compensation (in the range 0,5...2 bar of absolute pressure) is available as an option.

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.
