Tips: How to choose the size of the strain gauge?

Select the size of the strain gauge according to the material and stress conditions of the specimen, as well as the area where the strain gauge is allowed to be pasted. For large strain gages, it is recommended to use strain gages with a grid length of 3-6mm. If the stress concentration area of the specimen or the allowable bonding surface is small, it is recommended to use a strain gauge with a grid length of ≤1 mm. A strain gauge with a longer grid length has the advantages of easy bonding, wiring, and good heat dissipation. There is a certain improvement in the performance of the strain gauge. The smaller the size of the strain gage, the higher the requirements for the paste quality and the relatively poor heat dissipation. Therefore, on the premise of ensuring the measurement accuracy and sufficient installation area, it is appropriate to select a strain gage with a larger grid length.
