YEF series Post-yield strain gauge

These gauges are applicable to the measurement of large strain up to 10~15%. 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.
