METHOD OF TUNING OF SEMICONDUCTOR INTEGRATED STRAIN GAUGES AND DEVICE FOR ITS ACCOMPLISHMENT Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: a shunt of a definite size is connected to one of the pairs of bridge branches, where the total temperature sensitivity is higher than that of the other pair, to equalize the sums of temperature sensitivities. The value of the tuning resistor is selected in compliance with the developed condition. EFFECT: widened operating characteristics due to simultaneous temperature compensation and balancing of the initial value of output signal by equalizing the sum of temperature sensitivities of opposite branches of the piezoelectric transducer bridge with subsequent balancing of the initial value of output signal to 0. 3 cl, 3 dwg
