汽车仪表是监测发动机、辅助装置是否正常工作的设备。仪表大部分都集中在电线接头、连线以及一些传感器件上,这里主要谈谈传感器有关故障的检修。 传感器常见故障:温度传感器为热敏电阻,处在高温、剧烈震动条件下工作,长期使用,热敏电阻自身易发生断裂。油液位传感器是一种线绕可变电阻,靠浮球带动 Automotive instrumentation is to monitor the engine, auxiliary equipment is working properly equipment. Most of the instruments are concentrated in the wire connector, the connection and some sensor devices, the main talk here about the sensor troubleshooting. Common fault sensor: temperature sensor for the thermistor, at high temperature, severe vibration conditions, long-term use, the thermistor itself prone to fracture. Oil level sensor is a kind of wire wound variable resistor, driven by a float
