Our company aftermarket water temp gauge sender thread size has 1/8NPT, 1/4NPT, they are Thread specification，for English speaking countries using. And the aftermarket water temp gauge sender thread size M14×1.5mm , M16×1.5mm specification , are merric units. Customers can select the one which match to their water temp gauge .

About the aftermarket water temp gauge sender , the resistance value is about 30k Ω at - 40 ° C and about 1K Ω 2 at 90 ° C. The resistance of the aftermarket water temp gauge sender sensor will change with the temperature of the water, so it can also sense the temperature of the water. The temperature of the coolant will first cause the resistance change, and then cause the circuit voltage change. Send the voltage signal to the computer ECU, and the ECU can find the corresponding temperature of the coolant from the data stored in the computer according to the voltage signal. The computer adjusts the fuel injection quantity according to this temperature. When the water temperature is low, the fuel evaporation is poor, and the rich mixture is supplied, which is conducive to the cold start of the engine.

The aftermarket water temp gauge sender sensors are widely used in automobiles. There are five common aftermarket water temp gauge sender sensors: thermal resistance type, thermocouple type, thermal sensitive ferrite type, tube type and integrated type . At present , the main automotive applications include the thermistor aftermarket water temp gauge sender sensor in the thermal resistance type , the coolant aftermarket water temp gauge sender sensor in the liquid channel , the coolant aftermarket water temp gauge sender sensor on the dashboard , the interior aftermarket water temp gauge sender sensor installed under the windshield , and the intake air humidity aftermarket water temp gauge sender sensor installed on the air inlet .

The aftermarket water temp gauge sender, its internal structure is thermistor, and its resistance is between 275 ohms and 6500 ohms. The lower the temperature is, the higher the resistance is. The higher the temperature is, the lower the resistance is. The function of the first type of aftermarket water temp gauge sender sensor is relatively simple. It changes the resistance of the aftermarket water temp gauge sender sensor to change the current to drive the change of water temperature, indirectly telling people the working temperature of the engine.
