NH3/Oil switch

Technical data: HBLS

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.

 

Product features
