Capacitive Proximity SensorsIntroductionTechnical Reference Capacitive Proximity Sensors Capacitive proximity sensors are designed to detect both metallic and nonmetallic targets. They are ideally suited for liquid level control and for sensing powdered or granulated material. Strengths and Weaknesses Consider these strengths and weaknesses of the capacitive proximity sensor: Capacitive Proximity Sensor Attributes Attributes Strengths Can detect both metallic and nonmetallic objects at greater ranges than inductive sensors High switching rate for rapid response applications (counting) Can...

Capacitive Proximity Sensors Introduction Operation of the Capacitive Proximity Sensor A capacitor consists of two metal plates separated by a insulator (called a dielectric). The operation of this type of sensor is based on dielectric capacitance, which is the ability of a dielectric to store an electrical charge. The distance between the plates determines the ability of the capacitor to store a charge. Measuring the change in capacitance as an object enters the electrical field can be used as an ON/OFF switching function. Capacitor Operation Plates Capacitive Proximity Sensor Operation 4...

Capacitive Proximity SensorsIntroduction Capacitive Proximity Sensor Influences Many of the same factors that influence the sensing range of inductive proximity sensors, also influence the sensing range of capacitive proximity sensors. Environment Many of the same factors that affect inductive proximity sensors, also affect capacitive sensors, only more so. Typically, capacitive sensors have a greater sensing range than inductive sensors. Sensing distance for capacitive proximity sensors is dependent on plate diameter. With inductive proximity sensors, the size of the coil is...
