ABSTRACT:
A new extensometer is disclosed that avoids prior art problems of drift and other problems from variations in temperature, humidity and other environmental factors. Two primary extensometer body parts each hold at one end specimen contact rods and at their other ends a displacement measuring sensor, preferably a linear variable differential transformer. A thin hinge area connects the two body parts into a single piece monolithic construction so that relative movement between the two body parts is restricted to a single rotational degree of freedom.
