Oxygen detector-transmitter E2648-O2 is a member of new PluraSens® family of multifunctional measurement instruments.
The instrument 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 utilises novel fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long 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. We recommend to set the output scale within 20-100% of the detection range.
Two relays with closing contact (option) may be used for remote signalling or ventilation control. Default alarm set-points are 19,5% and 18,0% O2.
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.
The device is available with either attached or remote sensor probe (default cable length is 3 m).
