The CLS2 is a capacitive technology level switch that does not have any moving parts - no jams, no wear, nothing to break, and no maintenance. State of the art sensing technology in the CLS2, using impulse RF admittance measurement combined with an active guard, provides excellent level measurement and stability while being insensitive to material buildup. This technology also provides immunity to external RF sources like walkie-talkies and cell phones as well as minimal interference with radio communication or other electronic systems.

Capacitive level technology can be used for liquids, powders and bulk materials and is great for difficult applications such as slurries, coating products, and liquids and solids. The CLS2 is ideal for level indication in silos, receivers, and transporters in pneumatic conveying systems. The CLS2 can also be used for liquid interface applications to detect the level of two immiscible liquids that have different dielectric constants such as oil and water. Wetted materials of PVDF and 316 SS assure great chemical compatibility and meet food grade requirements.
