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.
Carbon dioxide transmitter E2658-CO2 is based on nondispersive infrared (NDIR) gas sensor with excellent selectivity and long lifetime. Ambient pressure compensation (in the range 0,5...2 bar of absolute pressure) is available as an option.
To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol.
Two relays with closing contact (option) may be used for remote signalling or ventilation control. Two alarm set-points are user settable.
