Single Point Sensors and Switches

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.
  • No moving parts in the probe
  • Low refrigerant temperatures possible
  • Plug-in electronics
  • Suitable for ammonia, R22, R134a, R404A, R507, and other Hansen approved refrigerants
  • Unaffected by normal splashing or oil coating
  • Reliable, non-optic
  • Stainless steel probe body

Applications

These level sensors and switches are designed specifically for use in refrigeration systems. They provide single point refrigerant liquid level detection for receiver/vessels, intercoolers, control pressure receivers, packaged chillers, compressor packages, pump packages, and flooded evaporators. In many cases, Hansen single point level sensors and switches
can be used in place of float switches, such as for high or low level alarms in conjunction with plant computers, PLCs, or shut-off solenoid valves.
