汽车仪表（Automobile instrument） The oil pressure sensor can be divided into two types of bimetal and variable resistance. Is the commonly used oil pressure indicator with electric heating type bimetal oil pressure sensor and solenoid type oil pressure indicator with variable resistance type oil pressure sensor). All kinds of sensors (coolant temperature sensor) The coolant temperature sensor not only provides the engine management system with the number, but also transmits the information to the driver through the instrument display. According to this, the information can be transmitted to the driver through the instrument display. Sixteen 2. Coolant temperature function: the coolant thermometer is used to detect and show the working temperature of the coolant in the engine water jacket, so as to prevent overheating of the engine due to the excessive coolant temperature. 2. Coolant temperature gauge Classification: coolant temperature indicator temperature indicator can be divided into electric heating, electric heating, electric heating and temperature indicator electromagnetic moving magnet three, coolant temperature sensor and electromagnetic dynamic magnetic sensing bimetal and thermistor type two. Which can be divided into double sheet metal and bimetal thermistor and thermistor type (commonly used is the electric type coolant temperature indicator with bimetal sensor, electric type coolant temperature indicator with thermistor sensor and solenoid type coolant temperature indicator with a thermistor sensor three.) 3. Fuel meter Function: fuel meter is used to indicate the storage of fuel oil in the fuel tank. Classification: there are three kinds of fuel meter: electromagnetic, moving magnet and electrothermal. The sensors are variable resistance. A variety of sensors (speed sensors) Magnetic pulse type Holzer type Twenty 4. Speedometer Function: speed odometer is used to indicate 1 vehicle speed 2 cumulative mileage meter. Classification: magnetic induction type,
