INVARIANT MEASUREMENT CONVERTER IN THE FORM OF VOLTAGE DIVIDER Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: given invariant measurement converter can be used in instrumentation engineering to design parametric measurement converters invariant to changes of parameters of power supply sources and other values exerting effect. Compensation of constant noninformative component in function of conversion is conducted to increase conversion accuracy. Proposed measurement converter includes converter with variable parameters, converter with constant parameters, power supply source, two voltage followers based on operational amplifiers, voltage adder based on one operational amplifier and resistors and divider. Converters are identical in make. EFFECT: increased conversion accuracy. 1 dwg
