Mini Capacitance Level Switch
The Mini Capacitance Level Switch is a compact, high-performance point level sensing instrument designed for precise detection of liquid and solid materials. Engineered for reliability, it delivers stable and trouble-free operation across a wide range of process conditions including varying temperatures, pressures, and material characteristics.
Operating on the proven capacitance measurement principle, the switch accurately senses level changes by detecting variations in dielectric constant between the sensing probe and the vessel wall. Its robust construction and sensitive electronics make it ideal for continuous use in demanding industrial environments where consistent level indication is critical for process safety and efficiency.
Product Share on :Applications
- Point level detection in silos, bins, hoppers, and storage tanks
- Powders, pellets, granules, ash, and dry bulk materials
- Rice, husk, food grains, and agro-based products
- Chemical, fertilizer, plastic, and polymer industries
- Material handling systems and bulk storage processes
- Suitable for both solid and liquid level sensing applications
Working Principle
The Mini Capacitance Level Switch operates by forming a capacitance between the sensing probe and the metallic wall of the vessel, which together act as electrodes. The process material inside the vessel functions as the dielectric medium.
As the level of the material rises or falls, the dielectric constant changes, resulting in a corresponding change in capacitance. This variation is detected by the electronic circuit and converted into a precise switching signal to indicate the presence or absence of material at the desired level point.
Construction
The switch is built with a rugged industrial design to ensure long-term durability. The sensing probe is manufactured from high-grade stainless steel (SS304 / SS316), providing excellent resistance to corrosion and process wear. The compact housing protects internal electronics and ensures stable performance even in harsh operating conditions.
Installation
- Easy side or top mounting on vessels, silos, and hoppers
- Standard threaded process connection for quick installation
- No complex calibration required
- Compact design suitable for limited installation spaces
