Capacitive level sensors without media contact


Available in:

30 versions

Need to detect and monitor fill levels in containers, pipes, or tanks without contacting the media through non-metallic container walls? This is not a problem for our capacitive level sensors without media contact. These devices detect the fill level of liquids and bulk materials to deliver reliable results.

Available in a wide range of versions, these sensors are suitable for a variety of applications. Choose from compact and flat cylindrical, cubic, or disc configurations, pressure-rated versions, and a variety of plug and cable variants.

Equipped with our patented Smart Level technology, the capacitive sensors from Balluff compensate for moisture, foam, and adhesion of any kind – even through glass and plastic walls up to 10 mm thick. This makes the sensors ideal as fill level sensors for conductive media, guaranteeing you high application reliability.
