Capacitance describes how two conductive objects with a space between them respond to a voltage difference applied to them.
Also, the amount of voltage change for a given amount of distance change is called the sensitivity.
Capacitance Level Sensor Measurement: Measuring Principle
The principle of capacitive level measurement is based on the capacitance change of a capacitor. In addition, the probe and the tank wall form a capacitor whose capacitance is dependent on the amount of product in the tank. Hence, An empty tank has a lower, a filled tank a higher capacitance.
Benefits of a Level Sensor
- Proven and tested measuring principle – robust and safe
- Universally adaptable probe
- Reliable operation also in strong build-up formation and viscous media
- Easy commissioning
Furthermore, If this does not fit your application, we have other types of Level sensors.
