Abstract
A speed sensor has a stationary electrode and a mobile electrode held normally at a specified distance from each other by an elastic supporting device. The speed sensor is attached to one of the wheels of a vehicle such as an automobile. The centrifugal force due to the rotation of the wheel is measured from the displacement of the mobile electrode with respect to the stationary electrode, and the traveling speed of the vehicle is calculated from the measured centrifugal force.
