Properly Installed Strain Gage Using a Bondeable Terminal
This photo is the hallmark of a properly installed Micro-Measurements EA-Series strain gage. Note the 3-wire, ¼-bridge connection of the instrument cable to the bondeable terminal. Solder connections are kept as small as possible to improve fatigue life and elongation capability of the strain gage. The thin, enameled, solid copper wire is routed from the strain gage perpendicular to the maximum strain, and the wire is looped to decouple strain transfer to the wire.
