Capacitive Sensors
Capacitive sensors will detect most materials - conductive and non-conductive. This makes them ideal for level detection in raw plastic delivery systems and in agricultural applications.
Gavazzi sensors are available in 12 mm, 18 mm, and 30 mm diameter with both AC and DC outputs. Carlo Gavazzi offers both plastic and metal housings with either a built-in cable or a connector.

Frequently Asked Questions
What materials can capacitive sensors detect?
Capacitive sensors detect most materials, conductive and non-conductive, such as water, glass, plastics, and metals. This makes them ideal for level detection in raw plastic delivery systems and in agricultural applications.
What sizes are Carlo Gavazzi capacitive sensors available in?
Carlo Gavazzi capacitive sensors are available in 12 mm, 18 mm, and 30 mm diameters with both AC and DC outputs. They come in plastic or metal housings with either a built-in cable or a connector. The CA18 series on this page includes versions with Teflon, PVC, and polypropylene housings.
Can capacitive sensors detect through container walls?
Yes. Their adjustable sensitivity makes it possible to tune out mounting hardware or intermediate barrier materials. The Carlo Gavazzi capacitive sensor brochure lists level control in non-metallic containers and level monitoring through a sight glass among typical applications. Models with the teach-in function can be programmed to detect material directly or inside a container.
