Level Sensors

A range of proven measurement methods is available for measuring the levels of liquids or bulk materials. In capacitive switch measurement, a change in the dielectric constant is detected and converted into a switching signal. The advantage of this technology is that the medium can be detected even partially behind container walls. Therefore, no drilling in the container is necessary. The function depends on the ratio of the dielectric constant of the medium to the dielectric constant of the container wall. A typical pairing is a water-based liquid behind a plastic or glass wall.
