C2.2 - High Performance Capacitive Sensor Electronic Interfaces for Displacement Measurement in Industrial Applications

Stoyan Nihtianov
Capacitive sensors are popular in industry because they have a simple construction and they perform well. As the name of the sensor suggests, the electrical model of the capacitive sensor is capacitance, the value of which is related to the value of the input variable. Naturally, the main function of the capacitivesensor electronic interface is to measure capacitance. This can be done in a number of ways by using different excitation signals. With harmonic excitation...
