ABSTRACT
In this work, differential strain-gauged pressure transducers and their sensing elements have been studied in detail. As a sensing element is pressurized, it becomes deformed and the bonded strain-gages extend and shorten. The electrical resistances of the strain-gages change as a result. Then, employing the electrical bridge circuits composed of the strain gauges, the output voltage is used to determine the pressure difference that is to be measured. Of the sensing elements, the finite element technique and optimization process provide analysis in designing three appropriate types of sensing elements of particular pressure difference ranges. Stress limit is imposed to obtain the optimal sizes of the sensing elements.
