热敏电阻作为测温用时,具有灵敏度高,热惯性小等优点,但由于其电阻温度特性的非线性,使测温电桥指示刻度不均匀,给应用带来不便。为此将热敏电阻R_T接入电桥滑线电阻R_P的对臂之一(如附图所示),经试验调整可使电桥刻度基本呈线性(见表2)。表1是一组 Thermistor as a temperature measurement, with high sensitivity, thermal inertia and other advantages, but because of the non-linear resistance temperature characteristics, temperature measurement results indicate that the bridge is not uniform scale, causing inconvenience to the application. To do this, connect the thermistor R_T to one of the opposing arms (as shown in the figure) of the bridge slip resistor R_P, and adjust the test bridge to be approximately linear (see Table 2).
