Abstract :
The paper presents a speedometer using a capacitive sensor. It uses a ratiometric measurement electronic circuit, feature that allows eliminating the effect of activation voltage variations. The prototype, with digital display, allows the rotational speed measurement in the range of 2,000 to 20,000 rpm, with an accuracy better than 1.5% full range.
