  • Patent number: 4638250
    Abstract: A position sensor device is provided which inductively measures the change in position of a shorted conductive loop coil that is oriented to move in conjunction with the machine part to be measured relative to a stationary assembly. The stationary assembly is made up of a magnetic field generator and a sensor, which are oriented to respectively create and receive the magnetic field which is coupled to the loop. As a result, displacement of the coupling coil varies the degree of coupling between the generator and sensor such that the magnitude of the induced electrical current is representative of the location of the loop relative to the stationary assembly. The device can be used for measuring angular rotation, linear position and the angle of rotation, and linear movement with respect to displacement from a predetermined null position.
