SLC Series

Sapcon’s Capacitance Level Limit Switch utilizing specially designed Immuno Coat Probe offers a solution for level limit detection of fine, coarse, bulky solids, non-sticky slurries and liquids. The measuring system consists of an evaluation unit, an electronic insert and a probe. It basically works by using the dielectric property of the material.

Principle

The probe comprises of a sense electrode, electrically isolated from the metallic tank by means of a suitable insulator. The sense electrode and the vessel wall serve as the two electrodes of a capacitor with the service material as the dielectric. A change in material level causes a change in the dielectric, which in turn causes the value of this tank capacitor to change.
