Easy-Laser® E420

Entry level Shaft to Shaft Laser Alignment - Redefined!

The Easy-Laser® E420 sets a new standard in entry level laser systems for shaft alignment. Wireless measuring units, a large 5.7” colour display and an IP65-rated design that withstands harsh environments. These are the features you would normally only find in more expensive systems! The measuring units are incredibly compact featuring Bluetooth® Wireless technology, an integrated rechargeable battery and large 20 mm TruePSD detectors. This means that they are easy to install on most types of machines, even where there is limited space. The wireless technology gives you full freedom of movement around the machine that is to be aligned. Programs for alignment of both horizontal and vertical machines are included. Added to that are functions for soft foot control, thermal growth compensation and tolerance control. 

E530 Shaft Alignment System

 

The measurement system is very easy to use. Pre-mounted units make it easy to install on the machine and the programs guide you step-by-step through the process. Start with the measuring units positioned anywhere on the shaft, recording three readings with as little as 20° of rotation between readings. Then adjust the machine with the live values, and save the measurements in the display unit memory. You can also transfer the results to the database EasyLink™ program (included) for PC. Easy-Laser® E420 has everything an entry level system should have, and more. Simply put, Easy-Laser® sets a new standard for measuring solutions. Take the next step into wireless freedom!

Easy-Laser® E420 Programs

Horizontal Machines - The measuring units (S and M) are mounted on each side of the coupling with cable or wireless communication to the display unit. Horizontally coupled machines often consist of a pump and motor, but there can also be other types of machine such as a gearboxes and compressors.
 

Vertical/Flange-Mounted Machines - Alignment of vertical and flange-mounted machines. Shows centre offset, angular error and shim value at each bolt.
 

Values - The Values program can be used e.g. when one wants to measure with dial gauges and to check bearing play. Can be used wIth the standard equipment and completely normal set up on the machine!
 

Softfoot Check - Start the alignment work by performing a soft foot check to ensure the machine is resting evenly on all its feet. This is necessary for a reliable alignment. The program shows which foot (feet) should be corrected. After the soft foot check you can go directly to the alignment program with all of the machine’s distances saved.
 

EasyTurn™ Function - 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 and your measurement is complete!
 

Thermal Growth Compensation - The Thermal Growth Compensation function allows the measurement system to calculate the correct shims and adjustment values when the machines (for example a pump and motor) expand considerably from a cold to a hot state (operating temperature).
 

Tolerance Check - Checks the offset and angle values towards a selected tolerance. Shows graphically when the alignment is within tolerance.
 

Measurement Value Filter - Advanced electronic filter function for accurate measurement results, even in bad measuring conditions like air turbulence and vibration.
 

Live-Any-Angle 360° - Allows adjustment of the machines live with the measuring units positioned anywhere around the shaft. Good for when machine parts prevent normal adjuster positioning.
 

Three Pairs of Feet / Pair of Feet in Front - The software can handle machine design of all types: two pairs of feet, three pairs of feet, pair of feet before the coupling, etc.

Easy-Laser® E420 Accessories

Easy-Laser® measurement systems are already extremely flexible in their standard form. By using clever accessories, you can adapt the systems for your own needs, now and in the future as your measurement requirements change. It is cost-effective. We have standardised measurements between the mounting holes in the different parts, and often there are mounting holes on several sides to facilitate mounting on the machine. Experience tells us that this is very much appreciated. A further advantage is that you can use one of the measuring units separately as a detector with, for example, our geometric laser D22. This expands the areas of application of the measurement system. Easy-Laser® is a system that is complete in its full meaning!
