CLS 01

Product Description

CLS 01 Capacitance Type Level Switch is designed for reliable level detection in conductive and non-conductive liquids, slurries, and solids. It operates on the capacitance measurement principle, where the probe and vessel wall act as electrodes to detect level changes based on dielectric variation. The switch provides a potential-free relay output for dependable alarm and control applications. Available with rigid or flexible probes in SS-316 / SS-316L with PTFE insulation, it supports probe lengths up to 3000 mm. With fast response time, high repeatability, and IP-rated weatherproof enclosure, the CLS 01 ensures trouble-free operation in harsh industrial environments. Multiple process connection options make it suitable for tanks, vessels, and open sump installations.
