The GS-1613 is a compact, lightweight sensor that can be installed into production equipment and existing fixtures, says maker Ono Sokki. Incorporating linear glass technology, the gage has been designed to measure dimension, thickness, curvature, eccentricity, displacement, height, depth, flatness, variation, runout, roundness distortion, deflection and position. Measurements as accurate as 0.00004" can be produced.
