The invention discloses a differential resistance type instrument dynamic monitoring device and method, and the method comprises the steps: carrying out the reasonable design of a conditioning circuit based on an existing standard five-core differential resistance type instrument, adding a voltage follower, enabling the conditioning circuit and the differential resistance type instrument to form a stable resistance bridge, and achieving the dynamic monitoring of the differential resistance type instrument. Voltage output signals including resistance sum and resistance ratio two parameters can be obtained at the same time, a high-speed AD acquisition card mode is adopted, a trigger signal and a stop signal are synchronously transmitted into a high-speed AD acquisition card, and meanwhile, the high-speed AD acquisition card is connected with the high-speed AD acquisition card. The high-speed AD acquisition card synchronously transmits the resistance ratio and resistance and double-parameter data of the differen
