HBLS is a level switch for detecting NH3 refrigerant and oil in industrial refrigeration systems. Typically it is installed on fluid tanks, also suitable for mounting other places where you need level indication of both NH3 refrigerant and oil.
The sensor is specially built to resist high pressure and low temperatures.
 |
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/oil is detected. |
|
Split design which makes it easy to install and make diagnostic on. The electronic part can be easily disconnected by 2 screws. |
