Title:Inductive Gage for Measurement of Load
Author(s):Roberts, H.C.
Subject(s):Gage, inductive
Load -- Measurement
Abstract:This paper describes the design and construction of an inductive-type gage for the measurement of load, intended especially for use in a fatigue machine, but applicable to other uses as well. Its performance, In terms of sensitivity, stability, and accuracy, is also described. The measuring element is a balanced inductance- type displacement-measuring gage, installed in a mechanical ring-type dynamometer. Excitation is by alternating current at 13,500 cycles per second; output is direct current at low Impedance, with polarity of output current indicating direction of application of load. Sensitivity, stability, and accuracy are all high. For static measurements a null system is used, but the instrument may also be used for dynamic measurements as a deflection-type instrument. The application of such an instrument in fatigue machines is described, as well as an alternate form of primary element.
