GIVE YOUR MACHINES CORRECT CONDITIONS FROM THE START

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 and check vibration levels. No other system on the market can offer this flexibility! Large, clear colour screen, wireless measuring units, long operating life and robust design give a measurement system that is both reliable and easy to use.

Easy to use = fast and efficient

Easy-Laser® E720 laser alignment system

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 machine, 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; English, Spanish, German, French, Portuguese, Chinese, Japanese, Korean, Italian, Dutch, Russian, Polish, Finnish and Swedish. The programs guide you step-by-step through the measuring procedure for the perfect measuring result.

PROGRAMS AND FUNCTIONS

The key to a quick and reliable measurement are programs that guide you through the measurement process. The Easy-Laser® systems support you with smart functions and a clear user interface. Still, it is not our products that do the job, but you as a professional technician!

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.

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!

CARDAN/OFFSET MOUNTED MACHINES

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

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 E180 BTA accessory.)

VIBRATION MEASUREMENT

The Vibration Measurement program allows you to measure vibration levels (mm/s, inch/s) and bearing condition (g-value). The program guides the user through the vertical, horizontal and axial points to measure on the machine. The result can be documented as usual. (Requires the E285 Vibrometer probe accessory.)

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 com- plete, you can go directly to the alignment program with all of the machine’s distance values saved.

EASYTURN™ AND MULTIPOINT

With the EasyTurn™ function you can start measurement anywhere on the turn. Turn the shafts with the measuring units to three positions in any direction with as little as 20° between to register the measurement value. Measurement is complete! For advanced applications, such as turbines, there is a Multipoint function where any number of measuring points around the whole or part of the rotation can be registered.

THERMAL GROWTH COMPENSATION

Oftentimes, machines expand considerably when moving from a cold to hot operating temperature. The Thermal Growth Compensation function allows the measurement system to calculate the appropriate shims and values needed to make adjustments in such cases. Compensation values for the machines are normally supplied by the manufacturers.

Result table

The result table shows how well your readings repeat and lets you save comments for each one.

TOLERANCE CHECK

Measurement results can be checked against pre-defined tolerance tables or values you determine yourself. This allows you to immediately see if the alignment is within the approved parameters, thereby considerably reducing the amount of time spent on alignment.

REFERENCE FOOT LOCKING

This function allows you to lock any pair of feet on the machine, giving you more freedom when aligning,base-bound or bolt-bound machines.

MEASUREMENT VALUE FILTER

An advanced electronic filter function can be used to achieve reliable results even under poor measuring conditions. Air turbulence and vibrations from adjacent machines are no match for the Easy-Laser® filter function!

LIVE-ANY-ANGLE 360°

This function allows you to adjust machines in real time with the measuring units positioned anywhere on the shaft. It is ideal for situations in which outside objects interfere with normal positioning.

MULTIPLE SETS OF FEET

The software can adjust to machine designs of all types such as those with two pairs of feet, three pairs of feet, and feet in front of the coupling, etc.

SWAP VIEW FUNCTION

The swap view function allows you to adjust the position of the motor on screen to correspond with the position of the machine in front of you, making it easier to understand adjustment directions.

CHECKING BEARING PLAY

All our measurement systems come with the extremely useful Values program. The program can be used e.g. when one wants to measure as with dial gauges and to check bearing play. 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.

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. 

FLATNESS MEASUREMENT

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

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.

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.

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.

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.

LEVEL

The Level program for display unit E51* is used together with the E290 Digital Precision Level. A digital level is perfect for installation, setting up and maintenance of precision machines, leveling of machine tables, rolls, etc – basically anything you can think of!
*E51 is included with the E710 and E9xx systems.

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 PSD The so called reversed measurement method with two laser beams and two PSD 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.
