Study of the Properties of High-Sensitivity Thermally-Stable Thin-Film Resistance Strain Gauges for Integral Pressure Sensors

Resumo

The operating principle and major causes of instability in strain-gauge pressure sensors under severe service conditions are discussed. New designs and technologies are proposed for high-sensitivity, thermally-stable, resistance strain gauges employing new materials. Technologies for increasing the stability of the parameters of these sensors are described.
