Easy-Laser® E970 - Parallelism

For parallelism measurement and more!

For parallelism measurement of rolls and other objects in numerous applications. The Easy-Laser® E970 Parallelism system 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.

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

The prism is moved along the beam, which is deflected to each roll that is to be measured, and maybe aligned. Both ends of the roll are measured, and you get an angular value which is compared to the reference line (base line) 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 metres, 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).

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.

Blog:"I havent had a measurement I couldn't get done"

Richard Henry is the Lead Alignment & Vibration Specialist and owner of Process Metrology in Ohio, USA. He has over 20 years of experience of solving machinery alignment issues in the manufacturing industry. He is also a happy user of the Easy-Laser E970 Parallel system. We decided to ask him a few questions about the knowledge and experience he has gained over the years. Read more

Measurement programs

The featured programs below are the most common used with this system. Please click here for a complete overview of possibilities.
*=accessories needed

Parallelism*

For parallelism measurement of rolls, rails, overhead tracks, gantries, metal sheet cutters, production lines, etc. 

Straightness measurement

With our program for measuring straightness, you can easily measure long shafts, rolls, bearings, bases, machine structures etc. All you have to do is define a number of measuring points, in advance or while measuring. You will be able to get the result for both the horizontal and vertical alignment, graphically as well as digitally. 

Flatness measurement

Program to measure flatness/twist of (for example) machine bases, machine tables, etc. With advanced "best-fit" calculations.

Squareness

For measurement of squareness in machines and installations.
