We develop advanced sensors for:

Industrial refrigeration
Commercial Refrigeration
Heat pumps

Liquid Level Sensor

Technical data: HBLC-HFC

HBLC-HFC is designed for the measurement of HFC refrigerant level in chillers, evaporators and condensers. The sensor is pre-configured to R134, but can be configured for other HFC types.  

The sensor detects the refrigerant and transmits the signal to an analog 4-20 mA signal.
