Principle
The capacitance level sensor measuring principle is based on the physical properties of a capacitor formed by the sensor and the vessel wall, the electric capacity is affected by the dielectric value of products. When the sensor is not covered, the dielectric constants = 1 (Air is usually = 1) when the sensor is covered, the dielectric constant will increase capacity, the electronic oscillator (1 MEGA Hz radio frequency) will create a resonating signal, which will turn the unit on or off for level control purpose.
