DD Series
One-side Gage

This gage is specially designed to separately measure bending and tensile stresses by simply bonding the gage to one side of a plate or beam. It works on the assumption that strain distribution in the section of a plate or beam which is subjected to both types of stress is linear.

Main Test Materials Metal Materials Backing Acrylic
Operating Temperature -10 to +70°C Materials Element Cu-Ni alloy foil
Compensation range - Strain limit 0.15%
(1500×10-6)
Bonding adhesive CN,P-2 Fatigue life at room temp. 1×105
(±1000×10-6)
