ABSTRACT
The output changes of two conventional strain gages (Cu-Ni and Ni-Cr) and a newly-selected strain gage for high-pressure hydrogen gas use (Fe-Cr-Al) in 90 MPa hydrogen and nitrogen gases were measured under unloading conditions to find a high-performance strain gage for high-pressure hydrogen gas use. The changes in the outputs of the Cu-Ni and Ni-Cr gages in hydrogen gas were much larger than those in nitrogen gas, and the Fe-Cr-Al gage showed almost the same output changes in both gases. These results imply that the Fe-Cr-Al gage is superior to the others as a strain gage for high-pressure hydrogen gas use. A large amount of hydrogen entered the Cu-Ni and Ni-Cr foils, and the electrical resistances of these foils were significantly changed by hydrogen exposure, whereas almost no hydrogen entered the Fe-Cr-Al foil, and its electrical resistance was not changed. These resistance changes of the foils as a result of hydrogen entry were consistent with the gage output changes in hydrogen gas.
