High temperature resistant glass metal tube splicing NTC temperature sensor.Moving object detection module

　　Thermistors and temperature sensors composed of NTC thermistor chips as core components and packaged in different forms are widely used in various temperature detection, compensation, and control circuits. They play a core role in converting temperature variables into required electronic signals in the circuit.

　　With the development of electronic technology, NTC thermosensitive chips are increasingly used in various situations that require temperature detection, control, compensation, and so on. At the same time, the NTC temperature sensor structure has put forward increasingly high requirements. In order to achieve high sensitivity and fast detection, the temperature sensor structure design must have strong mechanical performance.

　　However, the existing temperature sensors for glass ceramic splicing are composed of glass shells and ceramic tubes, which play a protective role in preventing pin pulling from causing glass shell cracking and electrical performance failure; However, ceramic pipes are relatively brittle and prone to cracking under stress, and their protective effect is not significant.

　　Therefore, glass metal tube splicing high-temperature and highly sensitive temperature sensors have the advantages of fast response speed, sensitive detection, and high mechanical strength. It adopts a front end flat head design where the glass shell is in contact with the temperature measurement point, resulting in faster reaction time. The metal tube is spliced with the glass shell, making the mechanical strength of the temperature sensor higher.
