A bondeable solder terminal placed adjacent to strain gage solder tabs is necessary for strain gages where the tabs may be too small to directly solder the instrument cable. Use of bondeable terminals is also part of installation techniques used when an installer wishes to maximize the fatigue life or the elongation capability of a strain gage. How the terminal and strain gage are wired together is of particular importance to the success of the installation. In this audio, Darryl Peterson and Tom Rummage discuss the how and why of strain gage terminal wiring.
