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.
Ethylene detector-transmitter E2658-C2H4utilises a fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime. Due to a special technical solution for humidity compensation (available as an option), the detector may be used even at humidity levels up to 100% RH.
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.
