Capacitive Proximity Sensors

Sometimes you just want to know what is hidden behind a surface - behind a wall, for example, or in a storage container, in a shipping container, or behind a cover. Level and feed monitoring is one example of an application for capacitive proximity sensors. From solid materials like paper or wood, to granules or liquids, the status of the product can be reliably detected during the production process and on final inspection. Is there something behind that cover? Is the filled package really full? How much paint is still left in the tank? For capacitive sensors these are easy questions to answer.
