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.
