Liquid Level Switch

Technical data: HBSR

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

Proven sensor technology for simple transsistor output PNP/NPN and NO/NC contact function. The NO/NC term refers to the state of the contact in "dry" condition, when not influenced by the liquid.
Designed for the industrial refrigeration industry - max pressure 100 bar.
Clear indication with LED when refrigerant is detected.
Split design which makes it easy to install and make diagnostic on.
