Strain measurement in high-pressure hydrogen gas environments
Kyowa Electronic

The movement toward the realization of a hydrogen energy society is accelerating, including fuel cell vehicles and the construction of hydrogen production and refilling stations. As hydrogen energy is stored and used under high pressure (tens to hundreds of MPa), research and development of hydrogen embrittlement of the metals used is required, and strain measurement is indispensable. Conventional strain gauges are affected by hydrogen penetration into the metal resistive foil, making stable strain measurement impossible because the electrical resistance changes under no load in a high-pressure gas environment. Kyowa's KFV strain gauge is a user-friendly product as it is installed in the same way as general-purpose foil strain gauges.

As a result of Kyowa’s research and development programs, it can measure strain even in high-pressure hydrogen gas environments, making it possible to directly measure and monitor the stress of a test piece. Find out more at the company's booth.
