ABSTRACT:
A flat coil velocity transducer includes a thin, flat coil mounted to a member whose velocity is to be measured. The convolutions of the coil are skewed so that regions at opposite ends of the coil contain predominantly upper or lower legs of the convolutions. The coil moves transverse to a magnetic field to induce voltage in the legs of the coil. However, the field induces voltage in one, but not the other, end region so that a resultant voltage is induced in the coil dependent on the strength and direction of the magnetic field, the number and length of the legs in the region, and the direction and velocity of movement.
