FIELD: physics.
SUBSTANCE: measuring transducer has a differential measuring circuit whose input is connected to the lead for connecting an excitation source, and the said circuit generates two signals. Difference between these signals is functionally related to the quantity measured. Switch outputs are connected to outputs of the differential measuring circuit. A resistor and two capacitors are connected in the negative feedback circuit of the operational amplifier. The first capacitor is connected between the noninverting input of the operational amplifier and the common wire.
EFFECT: increased sensitivity of the measuring transducer.
