Technical data: HBSR
HBSR is a level switch for the detection of Ammonia 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.
There are two types, one for liquid temperature -40..+50°C which should be used for refrigeration systems and one type for heat pumps with liquid temperature range +50..+80°C.

 |
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 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. |
