Abstract
A system for calibrating a strain gage transducer mounted on a rotating member comprising a mechanical switch capable of making contact from a stator to selected terminals on the rotor to provide both positive and negative shunt calibration of the transducer. In a first embodiment, calibration is carried out while the rotor is stationary, providing a simple, cost effective calibration system for most applications. In a second embodiment, special terminals permit contact while the rotor is in motion. In a third embodiment, simultaneous calibration and gage measurements are possible while the rotor is in motion providing a means of continuous correction which is especially advantageous in applications where the rotor is subject to a rapidly changing environment.
