HB Products HBSO1

HBSO1 are low temperature level switches used for detecting common lubricating oils in refrigeration systems. The switches are specially developed for low temperature applications. The HBSO1 versions are used for PAO, and mineral oil.

The HBSO2 versions are used for PAG and 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 electronic sensor head is the same as the one used for the regular HBSO1 and HBSO2 sensors. The mechanical part has got a special open design made for draining the stiff and sticky oil at low temperatures on the low-pressure side of a cooling plant.
