Ammonia detector-transmitter E2648-NH3 is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include refrigeration facilities and animal agriculture (cattle, pig and poultry livestock houses).
The instrument utilises novel fully calibrated and temperature compensated metal-oxide 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 25 and 35 ppm.
The device is available with either attached or remote sensor probe (default cable length is 3 m).
