What types of quantities can be measured through capacitive sensor?
But capacitive sensors can be effective in measuring presence, density, thickness, and location of non-conductors as well. Non-conductive materials like plastic have a different dielectric constant than air. The dielectric constant determines how a non-conductive material affects capacitance between two conductors.

Can a capacitive sensor head be used for level detection?
Our self-adhesive capacitive sensor head is especially suited for non-contacting, continuous level detection on container or pipe outer walls with a generous detection range. The sensor head is flexible and can be trimmed to the desired length.
How are capacitive sensors used in everyday life?
Capacitive sensors are able to detect different objects and media without contact and regardless of shape. With these sensors, the fill levels of liquids or bulk materials can also be detected in direct contact with the medium or through a non-metallic container wall.
How are non conductors measured in a capacitive sensor?
Non-conductors can be measured by passing the electric field through them to a stationary conductive target behind. Capacitive sensors are most often used to measure the change in position of a conductive target. But capacitive sensors can be effective in measuring presence, density, thickness, and location of non-conductors as well.
How big of a tube can a fork sensor detect?
Thin adhesions are ignored. Because of this, the fork sensors can also detect limit levels in fine, transparent tubes with a small diameter (≤ 6 mm). Detecting levels in containers, pipes or tanks through non-metallic walls is routine for our capacitive level sensors.
