Micro Epsilon CSH1.2-CAm1.4 Cylindrical Capacitive Sensor with 1.2 mm Measuring Range with Integrated Cable Electrical Connection
The principle of capacitive displacement measurement using the capaNCDT (capacitive Non-Contact Displacement Transducer) system is based on how an ideal plate-type capacitor operates. The two plate electrodes are represented by the sensor and the opposing measurement object. If a constant alternating current flows through the sensor capacitor, the amplitude of the alternating voltage on the sensor is proportional to the distance between the capacitor electrodes. The alternating current is demodulated and output as, for example, an analog signal. Capacitive sensors are applied for displacement, position and thickness measurement.
