High Temperature Automatic Transmission Oil Stainless Steel Temperature Sensor 5k Ohm 3470
Application description: Suitable for temperature control module in gearbox;
Assembly method: Bolt connection.
Installation location and function of transmission oil temperature sensor
The transmission oil temperature sensor is installed on the valve plate in the oil pan of the automatic transmission, and is used to detect the temperature of the hydraulic oil of the automatic transmission as the basis for the electronic control unit to perform shift control, oil pressure control and lock-up clutch control.
Dimension Of The Stainless Steel Temperature Sensor (mm)
Structure and working principle of transmission oil temperature sensor
Inside the transmission oil temperature sensor is a negative temperature coefficient semiconductor thermistor. The higher the temperature, the lower the resistance. The characteristic curve of its resistance changing with temperature changes can be seen in the characteristics of the negative temperature coefficient thermistor in the coolant temperature sensor. The computer detects the temperature of the hydraulic oil of the automatic transmission according to the change of its resistance.
Detection method of transmission oil temperature sensor
(1) Measure the resistance value of the oil temperature sensor
Remove the transmission oil temperature sensor, place the sensor in a beaker filled with water, heat the water in the cup, and measure the resistance between the two terminals of the sensor at different temperatures.
(2) Standard value of sensor resistance
Compare the measured resistance value with the specified value, if the resistance value is less than the specified value
If it is large, it should be replaced.
