FIELD: measurement technology. ^ SUBSTANCE: proposed transducer incorporates negative feedback and intermittent positive feedback circuits. Positive feedback circuit has series-connected amplifier, decoupling unit, and memory device. Input and output voltages across decoupling unit are not electrically connected. Decoupling unit has series-connected circuit-opening switch, memory device, and closing switch and functions to enhance measurement accuracy of transducer. ^ EFFECT: enhanced measurement accuracy of transducer. ^ 1 cl, 1 dwg |
