摘要： A non-contact angular position sensor has juxtaposed transmit and receive disks with a coupler disk, carrying a conductive attenuating pattern interposed therebetween. A pattern of inductive coils, which completely encircle both the transmit and receive disks have their inductive coupling individually attenuated in accordance with the angular position of the symmetrical conductive pattern on the intermediate coupling disk. The transmit disk is driven by a signal source which when received and demodulated by the receive coils and summed together provides a unique sinusoidal signal whose phase is indicative of the angular position of the intermediate coupler. The conductive pattern on the coupler is designed to provide a linear output.
