Liquid Level Switch - Heat Pumps

Technical data: HBSO-MT

HBSO1-MT (PAO & mineral oil) and HBSO2-HP (POE & PAG oil) are level switches for detecting common lubricating oils in heat pumps and similar applications where the oil temperature is between 40°C and 90°C (104°F to 194°F). 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.

 

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.

Split design which makes it easy to install and make diagnostics. The electronic part can easily be disassembled by 2 or 3 screws.
Designed for the industrial refrigeration industry - max pressure up to 150 bar.
Clear LED indication.
Temperature range 40 - 90°C.
