NH3 Liquid Level Switch

Technical data: HBSR-SSR-2

The HBSR-SSR-2 is a Level Switch designed for detecting ammonia and brine refrigerants. It is typically installed on refrigerant vessels, pump separators, or heat exchangers. The sensor is engineered to withstand high pressure and low temperatures, making it ideal for industrial applications.

Key features

  • Liquid temperature range: Operate across a temperature range of -30°C to 50°C (-22°F to 122°F).
  • Pressure tolerance: Rated for pressures up to 100 bar (1450 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.
