FA901-A/B electronic extensometer is a resistance strain type extensometer, when the extensometer with the specimen stretching, caused by the elastomer deformation and make the paste in the
The resistance value of the strain gauge attached to it changes, and the mv signal is output through the Wheatstone bridge.
FA901 series axial deformation extensometer, suitable for metal, non-metallic materials testing. Includes conventional extensometers, average strain extensometers,
Specialized extensometers (large pitch strand, concrete, rock, wood, etc.). Used to measure modulus of elasticity E, specified non-proportional elongation strength RP,
specified total elongation strength Rt, various elongation rates, strain hardening index n and other parameters.
