YEF series Post-yield strain gauge

These gauges are applicable to the measurement of large strain up to 10 to 15%. Also these withstand the repeated strain in elastic range (at strain level ±1500 × 10-6 strain) like ordinary strain gauges. However, these are not applicable to the measurement of repeated strain in a large range.

* Suitable when a large strain measurement is made after a few days or more of bonding the strain gauge.
