Abstract
A rotary transformer transducer system includes a rotatable shaft having a rotor and a transducer each mounted thereon, and a stationary member including a stator, with the rotor and stator coupling electrical energy therebetween without physical contact. A resistor mounted on the rotatable shaft is selectably switched to provide direct shunt calibration of the transducer without physical contact with the stationary member. A solid state switch, mounted on the shaft couples the resistor to the transducer. The switch is operated by a pulse coded signal coupled in the reverse direction through the rotary transformers normally provided to transmit the transducer signals.
