Easy-Laser® XT770 - Shaft alignment
With Easy-Laser® XT770 Shaft you can solve measurement and alignment problems of all kinds on most machine types. With this system you can carry out the following:
With Easy-Laser XT770 Shaft you can perform shaft alignment of horizontally and vertically/flange mounted machines, and align machine trains with an unlimited number of machines. You can also measure twist of foundation, soft foot, bearing clearance, and more.
2 axis PSDs (position-sensitive detectors) permits adjustment of your machine both vertically and horizontally at the same time, with measuring units in any position. We call it 360° Live adjustment.
With the XT770 you have a choice of several different shaft alignment measurement methods, e.g. continuous sweep and multipoint. This gives you the flexibility you need to achieve the perfect measurement result. Read more about the different measurement methods under the Features tab.
The EasyTrend program allows you to keep track of machine movement over time, during operation. This is useful when checking for thermal expansion and pipe strain issues for example. This type of measurement requires special DM brackets which can be ordered separately. Read more about dynamic measurement.
The Bore center program is used together with the Bore bracket kit (accessory) and its D75 laser transmitter. Either you use the XT70-M unit as detector, included with the XT770 system, or upgrade with the XT9 detector (accessory) to be able to measure smaller diameters. Different brackets can be used depending on the type of job.
As all other XT systems, the XT770 can be used with the display unit of your choice. The XT Alignment app can be run on virtually any iOS or Android device*, or the Easy-Laser XT display unit. Click here for list of compatible devices.
The XT display unit has a 13MP camera, and you can also get the it with a built-in IR camera as an option. This means you can add a thermal image of the machine before and after alignment. In the app you can easily create and share a PDF report containing all measurement data and images.

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. The preferred method for situations where the machine to be aligned is mounted on a moving object, and it is not possible to use the inclinometers (e.g., on ships, cranes, wind turbines etc.).
Ideal method for coupled machines where you manually rotate the shafts to any position. 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. An easier-to-use version of the three-point method (see 9–12–3).
Automatic recording of measurement values during continuous sweeping of the shaft. The easiest and quickest way to obtain the alignment status on coupled machines. Hundreds of points are registered. Start recording, rotate, and stop at any angle and you get the results instantly. Quality check of measurement is provided (see example down left).
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.
Used when the machines are uncoupled and when the rotation can be difficult to control. Rotate one shaft/unit at a time to pass with the beam over the other (stationary). Repeat alternately until enough measurement points are recorded. You can start and stop anywhere on the turn. Use it for big heavy machinery like gas turbines, wind turbines or gear boxes which can be difficult to rotate to a specific position.
The XT70 measuring units utilize dot-type laser and 2-axis square PSD surfaces. A state-of-the-art OLED display shows the angle of the unit, making it easier to position it on the shaft.
The diagonally positioned fastening screws set the unit in a grid-lock on the rods. Rigid aluminium housing for maximum stability. IP66 and 67, dust- water- and shockproof. Heavy-duty battery for very long operating times. Built-in wireless technology.
Rugged, robust, industrial grade tablet with wear resistant rubberized protective coating. IP66 and 67, dust- water- and shockproof. As standard a 13 MP camera for documentation is built-in, but you can also choose a model with IR camera added.
A large 8", glove-enabled touch-screen makes the information clear and the app easy to use. You can check battery status also when the unit is turned off .
Heavy-duty rechargeable battery for very long operatong times; up to 16 hours. Fastening points for shoulder strap (accessory).
