Providing real-time concentricity and angularity adjustment under load, AlignPRO effectively measures unwanted specimen bending due to load string misalignment. System consists of alignment fixture, strain-gauged specimen, software, and electronics, and supports 8- and 12-gauge alignment cells. Software monitors output from strain gauges mounted on either flat or round alignment cells, and output is used to calculate bending due to angular and concentric alignment errors.
