Wholesale Specialized Production Temperature Sensor Fit for Great Wall 2.8 Diesel. OEM: 3808020-0028-001, Automobile Temperature Sensor, Water Temperature Sensor

The effect of the water temperature sensor is that::
There are two kinds, one, the instrument display; two, the test water temperature for the computer to provide the fuel injection basis, increase injection when water temperature is low, it works abnormal, engine work abnormal, if water temperature sensor is damaged, computer Testing the water temperature signal, will also provide a backup program (water temperature 80) in order to prevent engine downtime, but then th

Principle of Temperature Sensor :

Working principle: the water level sensor in the container sends the water level signal to the Controller, the computer in the Controller compares the measured water level signal with the set signal, and obtains the deviation, then, according to the deviation of the nature, to water supply electric issued "open" "off" the instructions, ensure that the container reaches the level of the set. After the water intake procedure is completed, temperature-controlled part of the computer to supply heat medium of electric issued "open" instructions, the system began to heat the water in the container. When setting the temperature. The Controller only gives the command, cut the heat source, the system enters the insulation state. In the process of programming, ensure that the system does not meet the safe water level, control of the heat source of electric valve, thereby avoiding the loss of heat and the occurrence of accidents
