Techniques for Attaching Leadwires
to Unbonded Strain Gages

Strain Gage Selection

The use of gage types with preattached terminals is preferred in order to minimize chances of heat damage to unbonded gage backings during soldering. In addition, flexible backings are preferred to reduce chances of breakage during handling and cleaning steps.

Recommended Micro-Measurements types (in order of preferred selection):

  1. E-backed gages with Option W
  2. CEA-Series gages
  3. W-backed gages with Option W


Consult Micro-Measurements Catalog 500, Strain Gage Listings , and Tech Note TN-505, Strain Gage Selection , for detailed gage descriptions.
