We used a dial gauge. Since the scale was read with human eyes, minute changes might be overlooked at faster rotation speed. We were also worried about damages to the roller surface from the contact. KEYENCE's LS Series ensures reliable, accurate inspection and eliminates the worries involved with human inspection.
Thank you for using KEYENCE products. Measurement of rollers is one of the most popular applications of the LS Series because of its ability to produce stable measured values without being affected by different materials with varied surface conditions. By measuring both ends of the roller, you can measure inclination as well as eccentricity.
