Displacement Transducers (AC-07-XXXX Series)

AC-07-XXXX series displacement transducers are compact and rugged yet light in weight. These units are widely used for testing materials such as advanced composites, metals and polymers. They can also be used to test round and flat specimens to perform tensile, compression and cyclic tests. These extensometers include circuitry for auto-calibration against internal shunt reference, thus obviating the need for on-site calibration during installation.
