Liquid Level Sensor

Technical data: HBLT-A3

The HBLT-A3 capacitive Liquid Level Sensor measures liquid levels in refrigerant vessels, heat pumps, and other industrial applications. This intelligent sensor comes with a built-in microprocessor and has advanced control capabilities for modulating motor valves, stepper valves, or PWM valves.

Key features

  • Liquid temperature range: Operate across a temperature range of -60°C to 110°C (-76°F to 230°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.
