Introduction
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.
Technical details
| Proven sensor technology for simple transsistor output PNP/NPN and NO/NC contact function | |
 |
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. The electronic part can be easily disconnected by 2 screws. |
