Description

Refrigerant detector-transmitter E2648-HFC is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include cold storage warehouses, refrigeration plants, skating arenas, hotels.

The instrument utilises fully calibrated and temperature compensated MOS 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. For demanding applications, a NDIR sensor is available on request.

To connect the detector-transmitter 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 setpoints are 100 ppm and 500 ppm.

The device is available with either attached or remote sensor probe (default cable length is 3 m).
