摘要：The development of an apparatus for the measurement of linear thermal expansion coefficient
of metal by a single diffraction method has been developed. The development was made based
on several ideas from previous researchers, as well as to overcome several limitations which
yields insignificant results. The development includes the redesign of the primary holder
module, the temperature measurement module (using a thermocouple sensor connected to the
PC), and the measurement approach of the diffraction pattern distance by means of digital
video analysis techniques using Tracker software. The development of the modules as well as
the measurement approach that has been done yields very good experimental results. The
measured linear thermal expansion coefficient of aluminum has a high level of accuracy and
precision. The result is (23.100 ± 0.2186)×10-6
/°C, and compared from a reference, i.e., 23.000
× 10-6
/°C, the relative error of is 0.95% and the relative standard deviation is 0.43%.
