Abstract

Abstract

For the purpose of accurate measurement of temperature and pressure changes in cavity explosion, a gas temperature and pressure after explosion measurement system was built for closed explosion based on K-type thermocouple and pressure transmitter. By designing a heat-insulation protection device, sensors' sensitive areas and signal modulation modules were installed in two different seal cavities independently. By doing this, sensors' survival under blast wave was raised. Sensors and the protect device were tested at the scaled distance of 0.86 m/kg^1/3. Gas temperature and pressure after explosion efficient changing progress was gained and sensors can be restored to the initial state. The test result shows that by installing K-type thermocouple and pressure transmitter to proper protecting device, gas temperature and pressure changing progress after explosion can be measured at small scaled closed explosion.
