Microwave level switch penetrates into medium

Products level switch

The Kobold LNM microwave level switch is used for detecting levels of fill. The microwave field penetrates several millimetres into the medium. Foam, condensate or remains of the transported medium that have stuck on to the tank are not detected.

By using this principle of measurement, it is also possible to detect non-conductive media.

The level switch from Kobold Canada is particularly suitable for use with foaming media because the foam itself is not detected. The output of the level switch only switches when the coupling section is completely covered by the medium.

This means it is possible to install it into tanks regardless of position. In combination with the Kobold LZE or LZE-R weld-in sleeves, the probe provides a measuring point that has no dead space and meets hygiene standards.

The level switch is therefore very well suited for CIP/SIP cleaning.

The output signal (24 Vdc) can therefore be transmitted direct to an SPS for further processing.

Applications include:

  • level monitoring, for conductive and non-conductive media;
  • safe level monitoring, even with foam and deposits; and,
  • phase separation of oil and water.
