ABSTRACT:
An induced current position transducer has a multi-tap winding. The multi-tap winding allows for digital interpolation of position to a small fraction of a wavelength, thereby reducing the amount of analog interpolation performed by the transducer electronics. In addition, a multi-tap receiver winding enhances the total output signal strength, thereby allowing a smaller receiver winding length along the direction of the measurement axis. Furthermore, a multi-tap receiver winding exhibits low impedance, thereby improving the output signal time constant. The multi-tap receiver winding of this invention comprises a plurality of receiver winding loops offset with respect to each other along the measuring axis, and electrically connected in series. Preferably, the signal contributions of each loop combine to form a "vector circle".
