HBSO

HBSO – Oil switch

HBSO1 (PAO, PEO & 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 transcritical CO₂ refrigeration systems.

Ordering code

Proven and reliable sensor with NPN/PNP transistor output and NO/NC contact function
Split design which makes it easy to install and make diagnostic. The electronic part can be disconnected easily by 2 screws.
Designed for the industrial refrigeration industry - max pressure up to 150 bar
LED indication
Available for 0...80°C and 0...120°C (HT) oil temperature
For PAG oil applications the HBSO2 should be used.
