What are the advantages of capacitive sensors?

Capacitor -type sensors are used as a sensor component with various types of capacitors. The physical quantity or mechanical amount of measurement is changed into a conversion device for changes in electrical capacity. In fact, it is a capacitor with variable parameters. Below, let's take a look at the advantages of capacitive sensors.

The problem of zero error of inductive sensor

When an inductive sensor is located in the middle position, the output of the bridge should be theoretically zero, but in fact, there is always a zero -position unbalanced voltage output (zero -position voltage), resulting in zero errors, as shown in Figure 3.13 (a). Excessive zero -position voltage will make the amplifier saturated in advance. If the sensor output is used as a control signal for the servo system, the zero voltage will also cause the servo motor to heat up and even generate zero misunderstandings. The composition of zero voltage is very complicated, as shown in Figure 3.13 (b). It contains Kishe and high -second harmonic.
