YEF series Post-yield strain gauge

This gauge is designed for measurement of large strain up to 10 to 15%. Also it is durable to the measurement of repeated strain in elastic range (at strain level ±1500×10^-6) like as ordinary strain gauge. However it is not applicable to the measurement of repeated strain in large range. The CN-Y is recommended as an adhesive if the measurement is made after a few days or longer of strain gauge bonding. Large strain measurement is possible even after one year of bonding the gauge with the CN-Y adhesive. (Provided that the specimen is stored in room temperature.)
