Mini Capacitance Level Switch
The Mini Capacitance Level Switch is a compact and highly reliable level sensing solution designed for accurate detection of liquid and solid materials. It operates on the capacitance principle, where a change in material level alters the dielectric constant between the sensing probe and the tank wall, enabling precise level indication even under varying process conditions.
Engineered for trouble-free performance, this switch is suitable for applications involving powders, pellets, granular materials, liquids, resins, and bulk solids. Its rugged construction ensures consistent operation across wide temperature and pressure ranges, making it ideal for industrial environments.

Working Principle
The Mini Capacitance Level Switch works on the principle of capacitance variation. The sensing probe and the metallic tank wall act as two electrodes, while the process material (solid or liquid) functions as the dielectric medium. As the material level rises or falls, the dielectric constant changes, resulting in a proportional change in capacitance.
This change is electronically detected and converted into a reliable switching signal, providing accurate ON/OFF level indication for automation and process control applications.
Construction
The switch features a robust stainless steel probe with high insulation resistance, designed for long service life in harsh industrial conditions. The compact housing contains advanced electronic circuitry for stable and repeatable switching performance. Probes are available in multiple sizes and materials to suit different process requirements.
