A Static Analysis of Errors in Transducer Calibration Techniques Used for Blast Phenomena Tests.
Abstract
Strain gage transducers are commonly used in the formation of measurement circuits for recording different physical phenomena such as acceleration, displacement, pressure, etc. One method of rating used in these circuits is the shunt resistor calibration technique, which is considered both satisfactory and reliable. A mathematical model representing the static measurement circuit is used to study the effect of major parameters on the calibration procedure. Three parameters are considered: the length of the cable which connects the transducer to the rest of the measurement circuit elements, the nonlinear characteristic of the transducer, and the balanced potentiometer setting. The main advantage gained from this investigation is the improvment in measurement accuracy. Keywords: Army Corps of Engineers; Waterways; Experimental station; Statistical analysis; Static electrical response; and Strain gage bridge circuits. (Author)
