Water temperature sensor

Abstract

The invention discloses a water temperature sensor comprising a temperature sensing shell and a plug. The top end of the temperature sensing shell is provided with a shell hole. The lower end of the plug is connected with the upper end of a second copper sheet through the shell hole. The lower end of the second copper sheet is connected with one end of a spring. The other end of the spring is connected with the upper end of a first copper sheet. The lower end of the first copper sheet is electrically connected with the upper end of an alerter. The lower end of the alerter is electrically connected with the upper end of a temperature receptor. The lower end of the second copper sheet and the upper end of the first copper sheet are connected with insulating paper, and the spring is arranged in the insulating paper. An internal thermistor, the temperature receptor, the alerter and the spring are arranged so that the working effect of the sensor is enabled to be substantial, alarming is performed in case of excessively high temperature, and thus the automobile is not liable to be damaged and maintained and the expenditure can be saved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a water temperature sensor. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements, sensors are widely used in various fields of social development and human life, including the automotive field, and there are many sensors in the automotive field, including water temperature sensors, and most of the water temperature sensors are not effective. , When the water temperature is too high, it will not alarm, etc., which leads to inaccurate water temperature and makes the car easy to damage and repair, a waste of money and inconvenient. Contents of the invention [0003] The purpose of...
