These compact Single Point Level Sensors and Switches are economical solutions for reliable and accurate level detection. They are designed to detect the presence of ammonia or halocarbon refrigerant liquid (but not oil) at a specific location in vessels containing refrigerant by capacitance-type, non-optic sensing.
The computer-compatible, low-voltage signal output of the level sensor can be used directly with plant computers, PLC's, solid-state relays or other controllers. The relay output from the level switch is suitable for direct connection to solenoids, alarms, and computers. Single Point Level Sensors & Switches for refrigerants for Refrigerant Vessels, Compressor Packages, Pump Packages, and Flooded Evaporators.
