Oil Level Switch

Technical data: HBSO-SSR-2

The HBSO1 (for PAO & mineral oil) and HBSO2 (for POE & PAG oil) are Level Switches designed to detect lubricating oils in refrigeration systems. Commonly installed on compressors and oil separators, they can also be used in other locations within the oil system. The unique measurement principle allows these sensors to detect oil without detecting refrigerant, providing high accuracy even in challenging conditions with oil spray and foam.

Key features

  • CO2 system application: These robust switches are designed to withstand high pressure and temperature, making them suitable for transcritical CO2 refrigeration systems.
  • Liquid temperature range: Operate across a temperature range of 0°C to 80°C (32°F to 176°F).
  • Pressure tolerance: Rated for pressures up to 150 bar (2175 psi).
  • Power supply: They feature a universal power supply compatible with 90...240 V 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.

Product features

Proven and reliable sensor with solid stae relay output and NO/NC contact function.

The NO/NC term refers to the state of the contact in "dry" condition, when not influenced by the oil.
Split design which makes it easy to install and make diagnostic. 
Designed for the industrial refrigeration industry - max pressure up to 150 bar.
Clear LED indication.
Universal power supply 90...240 V AC.
