HBSO-U-PNP/NC-6-LT HB Products Low Temperature Oil Level Switch - IP66

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.

Product Features:

• Proven and reliable sensor with NPN/PNP transistor 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.
• The switch is special developed for low temperature applications.
• Oil temperature range -30° to +90°C.
• The mechanical part is made with a special open design for draining the stiff & sticky oil at low temperatures.
• Proven and reliable sensor with NPN/PNP transistor 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. The electronic part can easily be disassembled by 2 screws.
• Designed for the industrial refrigeration industry - max pressure up to 150 bar.
• Clear LED indication.
