Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and in particular relates to a novel water temperature sensor. Background Art

[0002] The main function of the water temperature sensor is to measure the water temperature. The main principle of the water temperature sensor is to use the size of the resistor to measure the water temperature. Generally, the resistance of the water temperature sensor is between 275 ohms and 600 ohms. The higher the temperature, the smaller the resistance, and the lower the temperature, the larger the resistance. Moreover, the accuracy of the water temperature sensor in measuring the water temperature is also very good. The main application of the water temperature sensor is to correct the injection amount. When the temperature is low, the injection amount is reduced.

[0003] After long-term use of the existing water temperature sensor, the surface of the sensor end is easily adhered by impurities or certain dirt, which will affect the accuracy of water temperature detection and is very inconvenient to use. For this reason, we propose a new water temperature sensor. Utility Model Content
