【Abstract】 The detecting circuit of traditional strain pressure transducer is discussed. Measures for improvement are given, the apparent output is increased and zero - point adjustment is realized. The change of elastic coefficient of the mechanical elastic body caused by temperature changes and that of sensitivity coefficient of the strain foil are compensated and the requirement of output linear degree is satisfied.更多还原
