The LS 6500 and LS 6600 are self-cleaning switches for level detection and dry-run resistance for solids and liquids. It is completely maintenance free and minimizes clogging of sticky products. It measures water and beer also sticky liquids such as toothpaste or honey also dry media like sugar and flour. It gives precise results and us unaffected by its mounting position. Sensor or condensate is not detected. This device are completely resistant against CIP and SIP agents. Measures products with dielectric constant more than 1.5 with a small and compact version of LS6600. Operational under harsh environments for best results.
