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.
Oxygen detector-transmitter E2658-O2 may be used to prevent critical decrease of O2 concentration as well as to control the absence of the oxygen in gas mixtures.
The instrument may be supplied with either electrochemical or optical (based of fluorescence quenching) sensor. Both electrochemical and optical sensors are fully calibrated and temperature compensated. If used under moderate conditions, optical sensor does not require field recalibration during the whole lifetime.
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.
