METHOD FOR MEASURING TEMPERATURE OF SHOCK-COMPRESSED GAS IN EXPLOSION WELDING Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: for taking measurements of photocurrent through a photodiode, which occurs under irradiation of shock-compressed gas via a diaphragm with a circular hole of diameter d, the diaphragm and the photodiode FD-K-155 are mounted in a light-tight sleeve, the diaphragm being placed at the end face of the sleeve and the photodiode being offset from the outer edge of the diaphragm by the distance r, where r = 125d; the sleeve is mounted in a stationary welded blank so that the diaphragm is at the level of the welded surface. EFFECT: more accurate measurement results. 1 dwg
