DEVICE CONVERTING PHYSICAL PARAMETERS INTO ELECTRIC SIGNAL Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device includes bridge circuit of resistance strain gauges, two generators of stable current, D.C. amplifier with differential input and output, two adders, two D.C. differential amplifiers, output unit, current setting unit, potentiometer. More accurate compensation of error of device is obtained due to use of bridge circuit of resistance strain gauges in the capacity of temperature-dependent pickup. EFFECT: increased accuracy of evaluation of pressure within wide range of working temperatures. 1 dwg
