USA - Pointek CLS100

Capacitance Level Switch

Pointek CLS100 is a compact, 2-wire inverse frequency shift capacitance switch for level detection of solids, liquids, slurries and foam in constricted spaces. Pointek CLS100’s short insertion length of 100 mm (4") and high level of application versatility make it a good replacement for traditional capacitance sensors.

Pointek CLS100 is designed with advanced tip-sensing technology that provides accurate, repeatable switchpoint performance. The PPS (Polyphenylene sulfide) probe [optional PVDF (Polyvinylidene Fluoride)] is chemically resistant with an effective process operating temperature range from -30 to +100 °C (-22 to +212 °F) (7ML5501), and -10 to +100 °C (+14 to +212 °F) (7ML5610). The fully potted design ensures reliability in a vibrating environment such as agitated tanks up to 4 g. When used with a SensGuard protection cover, the CLS100 is protected from shearing, impact and abrasion in tough primary processes.
