Easy-Laser E970 - Parallelism

For parallelism measurement of rolls and other objects in numerous applications. The E970 is especially suitable when many objects are to be measured and aligned, and when the distances are long. Any chosen object or the baseline can be used as a reference.

For parallelism measurement – and more!

Easy-Laser® E970 Parallelism system uses the traditional method where a laser beam is pointed alongside the machine and then deflected 90 degrees towards the measurement object by a pentaprism.

The prism is moved along the beam, which is deflected to each roll that is to be measured and perhaps aligned. Both ends of the roll are measured, and you get an angular value which is compared to the reference line (baseline) or a reference roll. Besides paper machines, printing machines, and rolling mills you can also measure and align rails, overhead tracks, metal sheet cutters, and many other types of machines.

The E970 is especially suitable when many objects are to be measured and aligned, and when measuring over a long distance. The maximum distance with a standard system is 80 meters, the number of measurement objects can be several hundred, but is more likely limited by other practical factors than the system software! The alignment of the rolls can be performed in live mode with instant feedback. You can add, remove, and remeasure objects any time during measurement. The result is displayed both graphically and digitally in a table, and a PDF report can be produced directly on-site. Then transfer the results to your PC and the database software EasyLink™ (included).

A versatile system for many different kinds of measurements

Easy-Laser® E970 is not only limited to parallelism measurement. You can also use the system to measure level, straightness, and flatness on wire sections (suction boxes), flatness on foundations, and straightness of rolls. With a few accessories, you can also do shaft alignment. This makes the E970 a very cost-effective solution for your maintenance department.
