Liquid Level Sensor - HFC, HFO & CFC

Technical data: HBLC-HFC

The HBLC-HFC sensor is specifically designed for measuring HFC, HFO, and CFC refrigerant levels in chillers, evaporators, or condensers - and transmits this information via a 4-20 mA analog signal. Although pre-configured for R134, it can be adjusted to detect other types of HFC, HFO, or CFC refrigerants.

Key features

  • Liquid temperature range: Operate across a temperature range of 0°C to 145°C (32°F to 293°F).
  • Pressure tolerance: Rated for pressures up to 100 bar (1450 psi).
  • Power supply: The sensor operates on a 24 V DC power supply.
  • LED indicators: Provides clear visual indicators for power supply and alarm status.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • Easy configuration: Configuration with a PC using HB Tool software.
