Electrostatic Capacity Type Level Switch LIC-80 (small type)
The electrostatic capacity between electrode and a tank wall (in case of a dielectric substance, it is itself) changes when measured objects ( liquids, fines, slurry, etc.) contact electrode projecting in a tank . This change is detected, and the electronic circuit in electrode carries out a conversion output into a relay signal (ON-OFF), and the existence of a measured matter is detected . An alarm or control is performed .
