KSR level sensors and transmitters are used to measure and transmit the level of liquids using the float principle with magnetic transmission in conjunction with a KSR control unit.
The float actuates small reed contacts through the wall of the guide tube. The 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 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 benefits:
* The simple operating principle is suitable for a wide variety of applications.
* Continuous measurement of liquid levels independent of physical or chemical changes in the liquid, eg, foam, conductivity, dielectric constant, pressure, vacuum, temperature, vapour, condensation, bubbles, boiling effects.
* Signal transmission over large distances.
* Simple installation and commissioning, onetime 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.
