Ø18 grey polyester box with 2 m PVC cable. Perfect for the detection of grain or solid products as a level indicator in tanks, silos or containers. Typical segments: agriculture, food and beverage, conveyor belts, plastic and rubber, etc., CB18CLN12NA, Capacitive sensors have the exclusive ability to detect virtually any material whether liquid or solid. Although capacitive sensors can detect metallic and non-metallic objects, they are traditionally used for non-metallic materials such as: Plastics industry: Resins or ground or molded products. Agriculture: Feed, solid or grain products. Timber industry: Sawdust, paper products and door and window frames. Materials are detected due to their dielectric constant. The larger the size of an object, the higher the density of the material and the better or easier it is to detect the object. The nominal sensing distance of a capacitive sensor refers to a grounded metal plate (ST37). For more information about dielectric classifications of materials, see Technical Data.
