Capacitive level switches are sensors with an electrical contact output at a specific liquid, powder, or bulk level. Their traditional use is for non-metallic materials such as: plastics industry, chemical industry, wood industry, ceramic and glass industry, and packing industry. A few models are no maintenance.

 

 

 

 

Model CLS1 Capacitance Level Switch For Solids, Liquids or Slurries, Fail-Safe Protection, <1 pF Sensitivity                   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.       Product Applications   High or low level detection in bins, silos, tanks, hoppers, chutes and other vessels where liquids, solids or slurries are stored.     Models & Ordering   Model Description CLS1 Capacitance level switch.
