Oil Level Switch - High Temperature

Technical data: HBSO1-SSR-1/xx-x/HT & HBSO2-SSR-1/xx-x/HT

The HBSO1-SSR-1/xx-x/HT and HBSO2-SSR-1/xx-x/HT are high-temperature Level Switches designed for detecting common lubricating oils in refrigeration systems. The HBSO1 models are ideal for PAO and mineral oil, while the HBSO2 models work with PAG and POE oils. They are typically installed in or on compressors and oil separators but can be used elsewhere in the oil system.

These switches use a unique measurement principle that allows them to detect oil without detecting refrigerant, making them perfect for high-pressure and high-temperature environments. They are calibrated to avoid false readings due to oil spray and can handle a small amount of foam.

These sensors are also suitable for use in transcritical CO2 refrigeration systems.

Key features

• Liquid temperature range: Operate across a temperature range of 0°C to 145°C (32°F to 293°F).
• Pressure tolerance: Rated for pressures up to 150 bar (2175 psi).
• Power supply: The switch operates on a 24 V AC/DC power supply.
• Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
• LED indicators: Clear LED indication for easy status checking.
• Easy configuration: Configuration with a PC using HB Tool software.
