Strain Gauge Installation Tutorial from A to Z.

Kevin describes the process for preparing a test article for strain gage installation, including surface preparation, gage bonding, and the application of a protective coating. With practice, installing strain gage sensors becomes a routine operation. It does require meticulous attention to detail and strictly following the procedures. A typical procedure includes surface degreasing, abrasion, cleaning, etching, and neutralizing, then adhesive application and curing, and finally, applying environmental protection. If a pre-attached lead wire option is not used, then there would also be steps for soldering and flux removal. Choice of adhesive and protective coating procedures and materials varies, depending on test requirements.
