Abstract

PURPOSE:To ensure a high-accuracy temperature compensation for the zero-point potential, by varying the driving voltage of a bridge circuit according to the temperature and at the same time giving a compensation to the temperature characteristics of the zero-point voltage of the output detected by the fixed resistance, which is inserted between the gauge resistances, with the potential similar to the temperature characteristics of the driving voltage. CONSTITUTION:The gauge resistances R1 and R2 show the positive resistance change in response to the pressure; while the gauge resistances R3 and R4 show the negative resistance change respectively. These resistances R1-R4 form a full bridge circuit with intervention of the fixed resistance (r) at each connection end, and the amplifier Amp inputs the voltage given from the reference power source VE to generate the driving voltage VB after the gain is set by the temperature-sensitive resistance element RT such as the thermistor or the like. This voltage VB is applied to the full bridge circuit. And the difference of potential caused between the output of the amplifier OP and the tap output of the resistance R is detected through the output circuit as the form of the pressure detecting voltage.
