Large Patterns Vishay Micro-Measurements Special Purpose Sensors - Large Patterns The strain gage patterns listed on these pages employ long measuring grids, and are most commonly used for specialpurpose applications where strain averaging is desired. For example, when measuring strain in concrete it is usually the average strain that is sought rather than any severe local fluctuations in strain occurring at the interfaces between the aggregate particles and the cement. size shown.

See also 750DU pattern. 750DT MATRIX SIZE In general, for strain measurement on nonhomogeneous material it is preferable to select a gage length that is large with respect to the size of the inhomogeneity. The large gage patterns listed in this section are well-suited to many of these applications. 28.2L x 5.3W N2A-XX-750DU-350 EA-XX-750DU-350 WA-XX-750DU-350 WK-XX-750DU-10C EP-08-750DU-350 SA-XX-750DU-350 SK-XX-750DU-10C micro-measurements@vishay.com 350 350 350 1000 350 350 1000 0.15% 0.15% 0.3% 0.3% 0.15% 0.3% 0.3% E, L, LE E, L, LE Document No: 11513 Revision 21-Aug-03 Large Patterns Vishay Micro-Measurements Special Purpose Sensors - Large Patterns size shown.
