About the QFRAB Series High Temperature Use Straingauges

QF series High temperature use strain gauge
This gauge utilizes polyimide resin as a backing. Strain measurement in high temperature up to 200°C is easily realized by bonding the gauge with room temperature curing adhesive NP-50B.

Temperature compensation materials
