MULTI-CHANNEL CONVERTER OF RESISTANCE OF RESISTIVE SENSORS INTO VOLTAGE Russian patent published in 2016 - IPC G01R27/02 

FIELD: measuring equipment; electricity.

SUBSTANCE: invention can be particularly used to measure resistance increment in remote resistance strain gauges or thermistors in multichannel measuring systems operating in conditions of intense industrial interference. Multi-channel converter of resistive sensors resistance into voltage comprises “n” of resistance transducers, “n” first, “n” second, "n" third and “n” fourth wires, four groups of key elements with “n” switch elements in each, reference voltage source, two equal reference resistors, three operational amplifiers and adder.

EFFECT: high noise-immunity of multichannel converter and conversion of resistance increment of resistance transducers into voltage.
