Operating principle of capacitive sensors
Capacitive sensors, a type of position sensors, are often also referred to as capacitive proximity switches. These sensors operate by a change in the electrical field that is in the active zone and thus in the environment of the so-called sensor electrode. Capacitive sensors can detect different media through non-metallic vessel walls or on bypass pipes, and frequently see use in level measurement. The detected medium increases the capacitance, which leads to a change in the output status of the sensor.
Consequently there are numerous applications for capacitive sensors, such as:
- Detection of metals and almost all plastics
- Detection of glass, ceramics, wood and paper
- Detection of conductive media or bulk materials
