Refrigerant Switch - 90..240 V AC

Technical data: HBSR-SSR-2

HBSR-SSR-2 is a level switch for the detection of NH3 and Brine refrigerants.

Typically it is installed on the refrigerant vessels, pump separators, economisers or heat exchanger.

The sensor is specially built to resist high pressure and low temperatures.

It has universal power supply 90...240 V AC - 50/60 Hz.

Product features
