Capacitance Level Switch

Metal plates are arranged in parallel and charge voltage and capacitance are generated.

Capacitance of the metal plates is determined by metal plate area S, distance between the two plates L , and dielectric constant of isolative material between the two plates εs. Insulators have specific inductive capacity. For example, air has approximately 1.0 specific inductive capacity. General insulators have 2.0 to 5.0 specific inductive capacity. If S is equal to L, capacitance C changes according to specific inductive capacity of insulators. Namely, capacitance level switch detects and measure material by capturing change of capacitance value. Ground electrode and detection electrode of the level switch function same as these metal plates. Insulator between the metal plates roles material to measure to detect level.
