A pressure sensor resistant to instantaneous high temperature gas shock
Aiming at the problem of destructive impact generated by pressure sensors that are resistant to instantaneous high-temperature gas shocks in high temperature of 1000℃ gas pressure shock environment. An effective pressurization method is designed and an structure of the pressure tube by adding a damping the inside is designed,through adding the damping tube,the temperature of the gas in contact with the chip can be reduced to below 300℃,ensuring reliable operation of the sensor. In addition,by designing the internal damping of the pressrure system,the sensor can withstand the impact of large instantaneous gas pressure. Through experimental verification and thermodynamic simulation analysis,it can be concluded that the structural design of the pressure system of the sensor can meet the environmental requirements of instantaneous high temperature gas pressure shock,achieving the goal of accurate measurement.
