Zusammenfassung: | The invention discloses a resistive sensor measuring circuit, and relates to the technical field of sensor measurement, and the resistive sensor measuring circuit comprises a plurality of comparison lines which are connected in parallel, an input line, an output line and a power supply line. The comparison circuit comprises a comparator, a positive input pin of the comparator is connected with an input circuit, and variable voltage is input into the input circuit; a reverse input pin of the comparator is connected in parallel with a sensor resistor and a known resistor; the output end of each comparator is connected with an output end resistor, the resistance values of the output end resistors connected with the comparators are in a multiple relation, the tail end resistors are connected to an output line in parallel, the output line is provided with the tail end resistors, one path of the output end resistors is connected to the tail end resistors in parallel, and the other path of the output end resistors s |
