Setting the standard for entry level systems

The Easy-Laser® E420 is an 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!

Compact wireless technology

The measuring units are incredibly compact featuring 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. 

Easy to use

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. 

  • Compact, wireless measuring units for use on most machine designs.
  • ​Integrated wireless units and rechargeable battery.
  • TruePSD technology with unlimited resolution.
  • Dual PSD, dual laser beams and dual inclinometers for superior control and accuracy.
  • IP65-rated design that withstands harsh environments.

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!

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.

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.

VALUES - DIGITAL DIAL INDICATOR

The Values program has a clear digital representation of the laser target, and a list view for recorded values. Use it to measure as with dial gauges and to check bearing play or shaft load. Can also be used to perform many types of geometric measurements.

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!

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.

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.

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!

Document your data

Connect to you computer

The display unit is connected to the computer via the USB port. It then appears on the desktop as a USB Mass Storage Device from which you can easily transfer files.
 

EASYLINK™ PC SOFTWARE

With the EasyLink™ database program you can save and organise all your measurements in one place, produce reports with both data and images and export to your maintenance systems. You can customise what your Excel reports should look like and what data should be visible and where it should be positioned. The program has a clear folder structure, where you drag and drop files from the display unit to the database. Create your own structure with folders for manufacturer, department or machine type for example. The database can also be located on a common server and shared with other users. For extra safety you can use EasyLink™ to make backups of what you have saved in the display unit.

MAKE A PRINTOUT

Quickly print all measurement data locally with a thermal printer (accessory).

BARCODE READER

The barcode reader is used to enter the measurement object data automatically before measurement, which can save you time, and minimizes errors. Barcode reader is an accessory.
 

SAVE IN BUILT-IN MEMORY

Save all measurements in the display unit’s internal memory. 
 

SAVE TO USB MEMORY

Save desired measurements on your USB memory. This enables you to take it to your computer to print reports whilst leaving the measurement system in place.
