Abstract

The temperature of the incoming flow in the intake duct of the engine not only requires accurate measurement, but also has a harsh operating environment and strict requirements on the performance of the temperature sensor. When the measured engine airflow is fast and the temperature is relatively high, the reliability of the thermocouple wire will be reduced. If the temperature sensor is not well sealed, the hot air entering the sensor will cause physical damage to the sensor itself. In this paper, a Z-shaped shell and a sealing structure of glass slurry sintering method are designed to solve the reliability and sealing problems of temperature sensors in high temperature environment. After testing, the basic error of the sensor is better than 1% FS within the measured temperature (-60 ~ +700) ℃. This design has the characteristics of good sealing, strong insulating ability, and is more suitable for high temperature gas measurement, which can ensure that the sensor can perform temperature measurement with high reliability for a long time in harsh environments.
