the r60d (rotary variable inductance sensor) is a dc non-contact angle position sensor.the operation is driven by a direct current of plus or minus 15 volts, and the r60d provides a smooth, plus or minus 7.5 vdc output proportional to the sensing range at the angle of plus or minus 60 degrees.rvit is designed to use a set of four printed circuit coils and a lightweight conductive spoiler to achieve superior performance and low inertial moments.during the operation, the light spoiler and the transducer shaft rotate, and the inductance of the printed circuit plane coil is changed.the resulting imbalance is accurately measured using a patented self-test circuit.the signal is then converted into a linear dc output voltage proportional to the rotor shaft angle.digital circuits have a strong resistance to environmental disturbances such as emi and rfi, and are compatible with most analog location feedback systems.calibration uses a complete and/or 60-degree sensing range, and r60d provides special performance at a cost effective price.it also has extensive operating temperature range, infinite resolution and extremely long rotation cycle life
