HBSR

HBSR – Refrigerant switch

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

Typically it is installed in/on the refrigerant vessels, pump separators, economisers or heat exchanger. The sensor is specially built to resist high pressure and low temperatures.

 

 

 

      

        

Product features Applications Specifications Ordering code
  • Proven sensor technology for simple transsistor output PNP/NPN and NO/NC contact function
  • Designed for the industrial refrigeration industry - max pressure 100 bar
  • Can be mounted with heating element in case of temperature lower than -30 degree celsius
  • Clear indication with LED when refrigerant is detected
  • Split design which makes it easy to install and make diagnostic on. The electronic part can be easily disconnected by 2 screws.
