Oil Level Switch - Low Temperature

Technical data: HBSO1-SSR-2-LT & HBSO2-SSR-2-LT

The HBSO1-SSR-2-LT and HBSO2-SSR-2-LT are low-temperature level switches designed for detecting common lubricating oils in refrigeration systems. These switches are specifically crafted for low-temperature applications, with the HBSO1 suited for PAO and mineral oils, and the HBSO2 designed for PAG and POE oils. They are typically installed on compressors and oil separators but can be used in various locations within the oil system.

Product 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).
  • Special mechanical design: The mechanical component is designed to drain stiff and sticky oil at low temperatures on the low-pressure side of a cooling plant.
  • Power supply: They feature a universal power supply compatible with 90-240V AC, offering flexibility for various installation scenarios.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • LED indicators: Clear LED indication for easy status checking.
