Car water temperature sensor

Product Code:LGNTC1012
Product Name: Car water temperature sensor
Specifications:LGQCSW
Product Remarks:
Product Category:Automotive Zone
Product Description:

The interior of the car water temperature sensor is the car water temperature sensor, and the lower the temperature, the greater the resistance; On the contrary, the smaller the resistance, the more it is installed on the water jacket of the engine cylinder block or cylinder head, which comes into direct contact with the cooling water. Thus obtaining the temperature of the engine cooling water.

principle
The electronic control unit measures the temperature of the engine cooling water based on this change, and the lower the temperature, the greater the resistance; Conversely, the smaller the resistance. The electronic control unit measures the temperature of the engine cooling water based on this change, which serves as a correction factor for fuel injection and ignition timing. Simply put, we can understand the current operating status of a car, whether it is stopped or in motion, or how long it has been in motion, by measuring the temperature of the engine water.

structure
The car water temperature sensor is installed on the water jacket of the engine cylinder block or cylinder head, in direct contact with the coolant, and is used to measure the coolant temperature of the engine. The temperature sensor used for the coolant temperature gauge is a negative temperature coefficient thermistor (NTC), whose resistance decreases with increasing temperature, and has a wire connected to the electronic control unit (ECU). The other one is a grounding wire As shown in the figure.

install
It is installed on the water jacket of the engine cylinder block or cylinder head, in direct contact with the cooling water.

role
Thus obtaining the temperature of the engine cooling water. The electronic control unit measures the temperature of the engine cooling water based on this change, and the lower the temperature, the greater the resistance; Conversely, the smaller the resistance. The electronic control unit measures the temperature of the engine cooling water based on this change, which serves as a correction factor for fuel injection and ignition timing.

consist of
Its interior is a semiconductor thermistor, and the lower the temperature, the greater the resistance; Conversely, the smaller the resistance. The electronic control unit measures the temperature of the engine cooling water based on this change, which serves as a correction factor for fuel injection and ignition timing.
