Overview:
1 Introduction Temperature detection is achieved by detecting the resistance value of the temperature sensor and converting the relationship between the resistance and the temperature curve. In order to reduce the measurement complexity of the temperature inspection circuit, the three-wire measurement method is often used in the engineering for temperature measurement. The schematic diagram of the measurement circuit is shown in Figure 1. 
2 Three-wire conductor voltage drop compensation mechanism The sampling mechanism of a single temperature sensor is taken as an example to analyze the working mechanism of the three-wire conductor voltage drop compensation.
The schematic diagram of the three-wire conductor voltage drop compensation circuit is shown in Figure 2.
