Technical data: HBSO
HBSO1 (PAO & mineral oil) and HBSO2 (POE & PAG oil) is a level switch for detecting common lubricating oils in gas and air. Typically, it is installed in/on the compressor and the oil separator, but it is also suited for installation in other locations where you like to detect oil. 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 ammonia or water. It is calibrated so that it is unaffected by oil spray and only allows a small amount of foam. The sensor is constructed to resist high pressure and temperatures. For oil temperatures above 60°C (140°F) the HBSO-MT or HBSO-SSR /HT must be used.
The sensor is suited for use on transcritical CO2 refrigeration systems.
