Liquid Level Sensor - AKS41 - Ammonia, HFC, HFO & CFC

Technical data: HBLT-A1

The HBLT-A1 capacitive Liquid Level Sensor is designed to measure liquid levels in refrigerant vessels, including those using ammonia, HFC, HFO, and CFC. It transmits an active 4-20 mA signal that correlates with the liquid level: 4 mA indicates no liquid, while 20 mA signals that the entire transmitter is submerged. This makes it a versatile tool for monitoring and controlling liquid levels in industrial refrigeration systems.


Product features

  • Liquid temperature range: Operate across a temperature range of -60°C to 80°C (-76°F to 176°F).
  • Pressure tolerance: Rated for pressures up to 100 bar (1450 psi).
  • Power supply: The sensor operates on a 24V DC power supply.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
