Capacitive level measurement
The sensor and the wall of the container form the two electrodes of a capacitor. When the level changes, the electrical capacitance between the electrodes also changes. This change is evaluated by the electronics and converted into an output signal. Robust cable and rod versions cover a variety of applications.
The advantages
Fully insulated instrument versions also measure aggressive liquids or highly adhesive media.
Partly insulated versions perform reliable switching in powdered and granular bulk materials. The construction and quarrying industry, in particular, benefits from the sturdy build of these instruments.
Measuring principle
The proven capacitive measuring principle is one of the most common measuring principles for level measurement in the industrial measurement technology. Sensor and vessel form the two electrodes of a capacitor. A capacitance change caused by a level change is processed by the integrated electronics and converted into a switching signal. The level measurement is carried out via the complete sensor length without a dead zone. Thanks to cable and rod versions, suitable instruments are available for all applications.
