The sensor has good sealing performance.
Description
technical field [0001] The invention relates to a light intensity sensor for detecting the light intensity change of gunpowder burning light. Background technique [0002] The combustion properties of gunpowder are different under different pressures and different formulations, and the burning light has the characteristics of high intensity, high temperature and instant extinguishment. Therefore, detecting the change of the burning light intensity of gunpowder in a closed pressure vessel is an important indicator for studying the burning performance of gunpowder. . However, the traditional detection of light intensity is to sense the change of light intensity through a photoresistor. This detection method cannot work under high temperature and high pressure, has low sensitivity, and cannot monitor the continuous change process of light intensity. Contents of the invention [0003] The object of the present invention is to provide a gunpowder combustion light intensity sen...
