A capacitive transducer is a passive transducer that works on the principle of variable capacitances. It is used to measure physical quantities such as displacement, pressure, etc. In this Trainer, a variable area capacitor in this range of 50 pF to 500 pF is used to produce oscillations. These oscillations are converted to voltage.
A plot between the output voltage and the angle subtended by the transducer is plotted.
