Bridge Excitation Levels for Strain Measurement
In this iNotes Video Presentation, Keval explains how material heat sink properties and strain gage resistance together form a limit to maximum useful bridge excitation voltage. Having the the maximum excitation voltage applied to a strain gage is almost always advantageous since it produces the best possible signal-to-noise ratio. Another variable to consider is the size of the strain gage, or rather, the surface area in contact with the test materal.
