Free Shipping on Orders Over $363.30 USD

Model CLS1 Capacitance Level Switch provides reliable point level measurement of solids, liquids and slurries in metallic or non-metallic tanks and vessels.

Model CLS1 detects the presence or absence of material in contact with the probe by sensing a change in the capacitance.

Electronics provide highly sensitive measurement detection (requires less than a 1 picofarad shift from ambient).

State of the art technology ignores material build-up on the vessel sidewall or along the probe assembly. One time calibration is simple with a single multi-turn potentiometer. Red LED on housing indicates sensor status.

Unit features an adjustable 1-30 second time delay and a 5 amp, SPDT fail-safe relay output. Model CLS1 can be mounted vertically or horizontally.
