在汽车仪表中,温度表是用来指示发动机冷却水温度的。实际装车使用中,时常把温度表传感器和温度表混用,造成温度表失准,甚至无法正常工作。下面粗浅地谈谈常见电热式、热敏电阻式温度表传感器及其温度表的正确配用问题。电热式温度表传感器与温度表配用时的电路原理见图1。温度表传感器内有活动触点P_1和固定搭铁触 In automotive gauges, the thermometer is used to indicate the engine cooling water temperature. Actual loading and use, often mixed with the thermometer sensor and thermometer, resulting in thermometer misalignment, or even unable to work properly. The following shallow talk about the common electric, thermistor thermometer sensor and thermometer with the right allocation problem. Electric thermometer sensor and thermometer with the circuit when the circuit shown in Figure 1. Thermometer sensor has movable contact P_1 and fixed contact
