Technical data: HBSO-LT
HBSO-LT is a low temperature level switch used for detecting common lubricating oils in refrigeration systems. The switch is special developed for low temperature applications.
The HBSO version of the low temperature oil switch can be used for all types PAO, POE, mineral oil and PAG 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.
