DEVICE FOR MEASURING THE VOLTAGE RELATIONS OF BRIDGE SENSORS EXERTION Russian patent published in 2017 - IPC G01R19/10 G01R17/00 

FIELD: measuring equipment.

SUBSTANCE: device for measuring voltage overhead ratio sensor includes a working (measuring) bridge 1, which is the diagonal measurement across the series-connected amplifier 2, a selectable peak detector 3, a storage capacity of 4, dual-square controlled frequency generator 5 is connected with a diagonal bridge power 1. The output is also connected to the output device, the operation control circuit 3 and a detector serially connected through a standardizer 6 pulses, the frequency-voltage converter 7 - Comparative supply diagonal of the bridge 8. In this measuring bridge diagonal 1 and 8 are connected in series. The frequency of the pulse at the output is directly proportional to the transmission ratio of the coefficients measuring and comparative bridges.

EFFECT: increased sensitivity of its work by the introduction of a negative feedback loop of dual-square controlled oscillator frequency, its output connected to the diagonal feeding of the working bridge.
