Capacitive sensors

Capacitive sensor for automation

A capacitive sensor is a non-contact sensor or sensor that controls systems via an electrical signal.

Application

Sensors and sensors are designed to be used in various automated systems when moving certain objects remotely without access to the object.

Capacitive sensors are widely used in industrial systems and equipment for monitoring the movement of objects and objects without making contact between the sensor and the monitored object. Capacitive sensors consist of:

• a pair of coaxial electrodes
• a capacitor
• an RC generator

Differences between capacitive and inductive sensors

Remote, non-contact sensors are an indispensable part of various manufacturing and industrial processes. Unlike the inductive sensor, the capacitive sensor responds to both metallic and non-metallic objects such as plastics, glass, bulk materials, water, oils, minerals. The inductive sensor is a special case of the capacitive and strictly profiled to respond only to metal objects./p>

Contactless sensors are suitable for use in:

• various areas of industry and automation
• control of moving elements
• tracking the number of parts and products
• regulating the level of liquids in opaque packages
• monitoring the integrity of various elements and materials
