KFV
Foil Strain Gage for Hydrogen Gas Environment
Summary
KFV is a foil strain gage that enables stable strain measurement under high-pressure hydrogen gas environments.
Features
The metal foil of conventional foil strain gages has the electric resistance changed by receiving hydrogen effect, thereby disabling stable strain measurement.
KFV strain gage receives less electric resistance change due to hydrogen, thereby enabling stable strain measurement.
