Easy-Laser® XT660 is the second member of our Generation XT alignment systems, built upon our new cross-platform technology. That means you will be able to display data on a multitude of different handheld devices, including our XT11. With XT660, you can carry out the following:

  • Align the machine.
  • ​Check base twist.
  • Check bearing play.
  • Check soft foot.
  • Document and share the results.

The XT660 measuring units utilize dot laser technology. This makes it possible to measure larger machines and longer spans than line laser systems. It also provides higher accuracy when backlash in the coupling is present. In addition, dot laser allows you to check more things when installing a machine, e.g. twist of foundation and bearing clearance.

With the XT660 you have a choice of several different measurement methods, e.g. continuous sweep and multipoint. This gives you the flexibility you need to achieve the perfect measurement result.

The XT products are rugged, rated both IP66 and IP67 water and dustproof. Along with long operating times, this guarantees you will be able to take on and finish even the tougher jobs.

User-friendly

Use the rugged Easy-Laser XT11 display unit, or install the free XT Alignment app on your iOS or Android device*. The intuitive user interface guides you through the measurement process.

Unique documentation possibilities 

The XT11 display unit has a 13MP camera. You can also get the XT11 display unit with a built-in IR camera**. This means you can add a thermal image of the machine before and after alignment. You can easily create and share a PDF report containing all measurement data and images.

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

The user interface is intuitive and guides you through the measurement process. It is animated and zooms into the most important things for each step. You can save the measurements of a machine for 'As found' and 'As left 'in the same file.

Vertical/flange-mounted machines

For measurement and alignment of vertically and flange-mounted machines.

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 indicators

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.

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.)

Vibration analysis*

Diagnose vibration level, unbalance, misalignment, and looseness. (Requires the XT280 accessory.)

Machine train (3 machines)

For alignment of machine trains with three machines. You can pick the reference machine manually, or let the program choose one that will minimize the need for adjustments.

Twist measurement

Program to measure flatness/twist of, for example, machine foundation, machine tables, etc.

Measurement methods

9-12-3

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

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 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.

Continuous sweep

Automatic recording of measurement values during continuous sweeping of the shaft. Hundreds of points are registered. You can start anywhere on the turn. Quality check of measurement is provided.
