LU Min-xun, SU Liang, LIU Xiao-dong. Development of high temperature strain measuring technique and the measuring system[J]. 2006, (12): 39-42. DOI: 10.13873/j.1000-97872006.12.013.
The measurement of high temperature strain is a difficulty in engineering measurement.The high temperature will bring bad effect on the sensors
the measuring instruments and the data.By analyzing the effect of the high temperature on the strain measuring process
a elaborate analysis on the strain gauge selection
parameter modification
temperature compensation and the data processing is made.A measuring system which is aiming at the measuring process is also developed.By applying in the measurement of surface strain of the continuous annealing furnace
a good strain-temperature curves and the strain distribution are obtained.The system is well done for most of the high temperature measurement.
