Capacitive sensors
Capacitive sensors enable them to detect and monitor objects of any material. Without the need for contact, metallic and non-metallic materials can thus be scanned. Therefore, capacitive sensors are often used in the measurement of liquids. But other materials are also recognizable for a capacitive sensor:
Liquids
Water
Oils
Chemicals
Metals
Wood
Plastics
Powder
Granules
Powder
