E2658 series is a new line of flameproof transmitters intended for use in ATEX Zones 2 and 22.
E2658 series devices are based on PluraSens® multifunctional platform.
Refrigerant transmitter E2658-HFC tilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime. The sensor is highly sensitive to a wide range of CFC, HFC and HFO compounds, including R-12, R-123, R-125, R-134a, R-143, R-22, R-404a, R-407c, R-410a, R1234yf and similar.
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.
