Capacitance Level Indicator

In capacitive level measurement, the sensor and the vessel form the two electrodes of a capacitor. Any change in level causes a capacitance change, which is in turn converted into a level signal.
Thanks to versions with shortenable cables and rods, the capacitive level sensors cover a wide variety of applications.

Since capacitance level sensors are electronic devices, phase modulation and the use of higher frequencies makes the sensor suitable for applications in which dielectric constants are similar.
