Introduction

Micro-Measurements WA- , WK- , and WD-Series Strain Gages are manufactured with integral beryllium-copper lead ribbons. To maximize the inherently good fatigue life of this gage/lead combination, the gage-to-instrument leadwire connection must also be highly resistant to fatigue damage. The techniques described here are recommended for applications where the cyclic strain endurance requirements approach the fatigue limits of the gage in use.

Wiring procedures for gages with integral solder dots instead of lead ribbons are described in Vishay Measurements Group Tech Tip TT-606, Soldering Techniques for Lead Attachment to Strain Gages with Solder Dots , and general strain gage soldering techniques are discussed in detail in Tech Tip TT-609, Strain Gage Soldering Techniques .
