Liquid Level Switch

Technical data: HBSC2-SSR-2

The HBSC2-SSR-2 is a level switch designed to detect CO2, Butane, Isobutane, and Propane refrigerants. It is commonly installed in or on refrigerant vessels, pump separators, or heat exchangers. This sensor is engineered to withstand high pressure and low temperatures, making it suitable for a range of industrial refrigeration applications.

Key features

  • Liquid temperature range: Operate across a temperature range of -30°C to 80°C (-22°F to 176°F).
  • Pressure tolerance: Rated for pressures up to 150 bar (2175 psi).
  • Power supply: Compatible with a 90–240 V AC power source at 50/60 Hz.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • LED indicators: Provides a clear visual signal when refrigerant is detected, improving monitoring and safety.
