STRAIN MEASURING MODULE AND STRAIN MEASURING SYSTEM

摘要

PROBLEM TO BE SOLVED: To easily detachably fix a gage holder for holding a friction type strain gage to a measuring object formed of various materials into various shapes.SOLUTION: A strain measuring module (10) is used for measuring strain of a measuring object (W). The strain measuring module (10) includes: a friction type strain gage (11); and a strain gage holder (12) that holds the friction type strain gage (11) by pushing it against the measuring object. The strain gage holder (12) includes a decompression space having a pressure lower than the atmospheric pressure formed between the measuring object (W) and the strain gage holder (12) so as to be fixed to the measuring object (W).SELECTED DRAWING: Figure 1
