Abstract
A device for calibrating strain gages and strain transducers. The device includes an assembly with a first section and a second section positioned in relation to each other such that a gap is defined between the two sections. A strain transducer is attached to the assembly across the defined gap. The assembly includes an adjustment device which alters the position of the sections in relation to each other, thereby redefining the gap. A displacement sensor detects a displacement signal occurring due to the redefining of the gap caused by operation of the adjustment device. A strain transducer output detector detects a strain output signal occurring also due to the redefining of the gap by the adjustment device. A calibrating device inputs the signals from the displacement sensor and the strain transducer output detector and provides a calibration for the strain transducer attached to the assembly.
