Oil Level Switch - High Temperature

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

HBSO1-SSR-1/xx-x/HT and HBSO2-SSR-1/xx-x/HT are high temperature level switches for detecting common lubricating oils in refrigeration systems. The HBSO1 versions are used for PAO & mineral oil. The HBSO2 versions are used for PAG & POE oil. Typically, it is installed in/on the compressor and the oil separator, but it is also suited for installation in other locations in the oil system. The sensor's measurement principle makes it unique for these purposes, since the properties of the measurement principle allows it, among other things, to detect oil without detecting refrigerant. It is calibrated so that it is unaffected by oil spray and only allows a small amount of foam. The sensor is also constructed to resist high pressure and temperatures.

The sensor is also suited for use on transcritical CO2 refrigeration systems.

Product features

 

Proven and reliable sensor with solid state 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.
Designed for the industrial refrigeration industry - max pressure up to 150 bar.
Clear LED indication.
Split design which makes it easy to install and make diagnostic. The electronic part can be disconnected easily by 2 screws.
Temperature range: 0...+145°C.
