251374 Parker Refrigerating Specialties LVSW, HBSO1-NPN/NC-2 Oil, 3/4" NPT

Details

HBSO1 (PAO, PEO and mineral oil) and HBSO2 (PAG oil) is a level switch for detecting common lubricating oils in refrigeration systems. 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 so as to resist high pressure and temperatures. The sensor is suited for use on trans-critical CO2 refrigeration systems.
