All liquid level switches with circular electronic unit HBSC2, HBSR, HBOR & HBSO
Functionality and labelling:
The switches are used for detecting liquid in gas or air (HBOR detect oil in liquid
ammonia). The mechanical elements have different design because they are
optimized to different liquids. The switches use the capacitive measuring principle
and react to the difference in dielectric constant between liquid and gas.
The switches have different calibration and parameter settings in the electronic
unit, but unit is the same. The settings cannot be changed by the user, and it must
match the mechanical part. Switches delivered after September 2020 has a build
in heater which will be in operation below 5°C to keep the sensor dry
The switches are delivered as NO/NC and NPN/PNP connection. The switches
setting is printed on the small silver label on the switch together with the type
code. On the same label you find a combined version number and manufacturing
date and in second row a unique production number.
