Easy-Laser® E720 - Shaft alignment and geo applications

Give your machines correct conditions from the start

With Easy-Laser® E720 we include our very versatile laser transmitter D22, and all geometric apps. With this measurement system you can perform almost any kind of machine set-up and quality check.

Easy-Laser® E720 is the all-in-one alignment solution for the maintenance technician and millwright. It does not just give you all the functions for shaft alignment, it also gives the opportunity to check the machine base and levelness. ​

Machine set-up most often starts with the foundation. If the foundation is level and flat you will have less problems with the rest of the installation and alignment of the machine. With Easy-Laser® E720 you not only get all the functions and features for the alignment of the machine, but also possibilities to perform the following:

  • Measure the flatness of the foundation
  • Check plane parallelism for several surfaces on large machines
  • Measure flatness for a single machine foot support surface
  • Align the foundation level and plumb
  • Align pipes straight and square

The measuring units included with system E720 uses point laser and PSD technology. This is the reason it can be used in so many more places in your operations than just to align the shafts of rotating machinery.

All our measurement programs are included

Programs for Horizontal machines, Soft foot checks, Machine trains, Vertical/flange mounted and Cardan/offset mounted machines are included. Furthermore programs for Straightness, Flatness/Twist, Level and Parallelism measurement are included, to mention just a few. Using accessories you can also align sheaves/pulleys with digital precision. 

Easy to use = fast and efficient

When we talk about simplicity we mean several things, for example, simple to place or mount the measurement equipment on the measurement object, easy to perform the measurement and easy to interpret the measurement result. With Easy-Laser® E720 you can measure all types of rotating machinery, large and small, equally well, regardless of shaft diameter.

Wireless measuring units (laser/detector) enable you to work more freely. The measurement values can be registered with only 40° rotation of the shafts. You can then align it ”live” using the measuring units in any position around the shaft. The read off unit program is available in several different languages which facilitates use. The programs guide you step-by-step through the measuring procedure for the perfect measuring result.

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

Horizontal machines

Horizontally mounted machines often consist of a pump and a motor, but can also include other types of machines such as gearboxes and compressors. Regardless of the machine type, it is easy to measure and align with Easy-Laser®. The measuring units (M and S) are easily mounted on each side of the coupling and communicate with the display unit wireless. Then follow the step-by-step instructions on screen.

Vertical/flange mounted machines

This program is used for alignment of vertical and flange-mounted machines, e.g. pumps, motors, gear boxes. Shows centre offset, angular error and shim value at each bolt.

Machine train

Regardless of what machines you have and in which order they were assembled, you can build your own machine train with theoretically as many machines as you like. You can pick the reference machine manually, or let the program choose one that will minimize the need for adjustments. 

Cardan/offset mounted machines*

Alignment of cardan/offset mounted machines. (Accessory Cardan fixture, Part No. 12-0615 is required.)

Soft foot check

Alignment work begins with a soft foot check. The soft foot check ensures that the machine is resting evenly on all its feet by indicating which foot/feet should be adjusted. This is an important part of securing a reliable alignment. After the soft foot check is complete, you can go directly to the alignment program with all of the machine’s distance values saved.

Twist measurement

The twist measurement program allows you to check the flatness or twist of the machine foundation using only the measuring units in the system. 

Values - Digital dial indicator

The Values program can be used e.g. when one wants to measure as with dial gauges and to check bearing play or shaft load. With the standard equipment and completely normal set up on the machine!

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. To get even more out of your system, add the D22 swiveling laser.

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.

Parallelism*

For parallelism measurement of rolls, rails, overhead tracks, gantries, metal sheet cutters, production lines, etc. Two methods are available: measurement with Angular prism or with Angle detector E2.

Offset and angle

This program shows centre offset and angular error between two shafts, for example. The values are displayed for both horizontal and vertical direction simultaneously. Can also be used for dynamic measurements.

Spindle direction

For measurement of the pointing direction of machine spindles in machine tools, drilling machines, etc.

Centre-of-circle, Straightness 2-point

Used for straightness measurement of bearing journals when the bore diameter varies. For example, diesel engines, propeller shaft installations, etc. With advanced "best-fit" calculations.

Flange flatness

For flatness measurement of flanges and circular planes, slewing ring bearings and tower flanges for example. Can handle 1 to 5 circles, 3-180 measurement points on each. Three zero points at 120° pitch are computed by the system.

Flange parallelism*

For parallelism measurement of flanges on for example wind tower sections. With advanced "best-fit" calculations.

Half circle, Straightness 3-point

Readings taken in three positions: 9, 6 and 3. Allows varying diameters. To be used together with the turbine system. With advanced "best-fit" calculations.

Straightness, 4-point

Used for straightness measurement of bearing journals. Measures two points in each direction, X and Y. Can handle up to 999 measurement points with two zero points. With advanced "best-fit" calculations.

Straightness, Multipoint

Used for straightness measurement of bearing journals. The number of measurement positions are theoretically unlimited for each measurement point. Can handle up to 999 measurement points with two zero points. With advanced "best-fit" calculations.

Ovality/roundness

For ovality measurements of bore and bearing journals. The number of measurement positions are theoretically unlimited for each bore.

Belt alignment*

Using the system you can align sheaves and pulleys with digital precision. Adjustment of the machines is displayed in real time on the screen, with readings for angle and axial displacement in both the vertical and horizontal axes, as well as an adjustment value for the front or rear foot pair. The result can be documented as normal. (Requires the XT190 BTA accessory.)

Measurement methods

9-12-3
9-12-3

Measurement points are recorded at fixed points 9, 12 and 3 o’clock. This is the classic three-point method which can be used in most cases.

EasyTurn™ function
EasyTurn™ function

The EasyTurn™ function allows you to begin the measurement process from anywhere on the turn. You can turn the shaft to any three positions with as little as 20° between each position to register the measurement values. Voila! Measurement is complete!

Multi point
Multi point

Multi point is basically the same as EasyTurn™, but instead you can record multiple points on the sector rotated. This will provide an optimized calculation basis. Perfect for e.g. turbine and sliding bearing applications.

You can choose the language that you want to appear on screen. English, German, French, Spanish, Portuguese, Swedish, Finnish, Russian, Polish, Dutch, Italian, Japanese, Korean and Chinese are available. 

Upgrading

If you wish to expand functionality in the future, the software in the display unit can be upgraded via the internet or by connecting a USB memory containing the new software. In this way you will also have access to the measurement programmes that we develop for new purposes in the future.

  1. Two Enter buttons, for left and right-handed users
  2. Large, easy to read 5.7” colour display
  3. Proper buttons for clear feedback
  4. Thin profile gives a perfect grip for your hands

Measuring units ES / EM

The measuring units have large 20 mm [0.78” sq] detector surfaces (PSD for the greatest accuracy) which allows the possibility of measuring at a distance of up to 20 metres[66 feet]. The substantial and rigid design of aluminium and stainless steel guarantees stable measurement values and reliable alignment with the greatest precision in even the toughest of environments. The measuring units are also water and dust proof to classes IP66 and IP67. Connect to the display unit via cable or wirelessly. Both cable and wireless units are connected quickly using Push/Pull connections, no screwing required.

Inclinometers in both units

With electronic inclinometers in both measuring units the system knows exactly how they are positioned. This also makes it very easy to align uncoupled shafts.

Electronic targets

Thanks to the two axis detectors you have access to electronic targets, that is you can see on the screen where the laser beams hit.

Flexible mounting options

The thinking behind the rigid and compact design, is that it will simplify positioning and provide varying installation methods. You can measure all types of rotating machine, large and small, equally well, regardless of shaft diameter. The units also have two extra screw holes for additional mounting options.

Two lasers, two PSDs

The so called reversed measurement method with two laser beams and two PSDs makes it possible to also measure very incorrectly set machines. This is particularly good for new installations, where the machines are not yet in the correct position.

  1. The rods have a height of 60–180 mm. If necessary they can be extended "infinitely" with additional rods. Made of stainless steel.
  2. Well protected connectors
  3. PSD (2 axis)
  4. Laser aperture

D22 Laser transmitter

Laser transmitter D22 can be used to measure flatness, straightness, squareness, level and parallelism. The laser beam can sweep 360° with a measurement distance of up to 40 metres [130´] in radius. The laser beam can be angled 90° to the sweep, within 0.01 mm/m [0.01 mils/inch].

The transmitter has many mounting options. Attach it with the three magnetic feet, horizontally or vertically. Attach it with a pin in the spindle. Or put it beside the machine on for example a tripod (optional).
