Level switch KMW is microprocessor based and can be installed in any
position in tanks or piping systems.
The measuring principle is an electromagnetic wave (100…180MHz). A high frequency signal sweep is radiated from the sensor tip into the tank or pipe. The medium acts as a virtual capacitor, which together with a coil in the sensor, will form a circuit creating the switching point. This virtual capacity will depend of the dielectric value of the medium and is well defined for most media.
Therefore the KMW is suitable for almost all liquids and paste-like medias.
There are 7 base settings for several medias. To adjust the sensitivity there are two possibilities, by internal dipswitch or via PC with software. The characteristics of the medias are visualizable and adjustable with the PC-USB interface software.
For viscous and adhesive medias the KMW is available with extended PEEK sensor. Applications are high and low level detection in tanks and dry run protection of pumps in the Food & Beverage and Pharmaceutical industry. All common hygienic process connections are available.
