It is based on the float principle with magnetic transmission in a 3-wire potentiometer circuit. A float with a built-in magnetic system actuates small reed contacts through the wall of the guide tube.
These reed switches form a resistance measuring chain that continuously generates a voltage proportional to the height of the level. The resistance measuring chain is closely stepped and is made up from small chips soldered onto a PCB.
Due to this assembly the generated voltage is virtually continuous. Depending on requirements and design different contact separations from 5 to 20 mm are available.

Technical Advantages of KSR Level Sensors / Transmitters
The simple operating principle is suitable for a wide variety of applications.
Continuous measurement of liquid levels independent of physical or chemical changes of the liquid, e.g. foam, conductivity, dielectric constant, S.G., pressure, vacuum, temperature, vapour, condensation, bubbles, boiling effects.
Signal transmission over large distances.
Simple installation and commissioning, one-time calibration only, no re-calibration necessary.
Display proportional to the height of the level or the contents of the vessel.
Set point relays continuously adjustable over full range.
