Easy-Laser® XT770 Shaft+GEO - Shaft alignment and geo applications
The XT770 Shaft+GEO system has all the programs and functions you need to install and keep your machines up and running. Compared to the standard XT770 Shaft it also comes with a separate laser transmitter. With XT770 Shaft+GEO you can carry out the following:
With XT770 Shaft+GEO 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 straightness, flatness and 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.
You have a choice of five 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 system includes laser transmitter XT20 or XT22, which allow you to take flatness and straightness measurements with the highest reliability and precision.

The Bore center program is used together with the Bore bracket kit (accessory) and its XT24 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 Shaft+GEO 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 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).
Laser transmitter XT20 can be used to measure flatness and straightness. The laser beam can sweep 360° with a measurement distance of up to 20 metres [65´] in radius. The laser head is super stable, but still easy to turn. No need for locking/unlocking screw. The laser head fine turning knob makes it very easy to point the beam at the detector also on long distances (gear ratio 1:132).
We have installed electronic precision vials in the XT transmitters. This gives the advantage of faster feedback when levelling and less risk of errors during calibration, because all users see the same angular value (compared with reading spirit levels).
The XT transmitters have wireless connection to our XT Alignment App. This means that you get warning messages during measurement about events that can affect the result negatively, for example if the transmitter position might have been affected, or temperature changes inside the unit. We can also let the app guide you step-by-step when calibrating the levels before measuring.
The transmitter has many mounting options. The three super magnets can be mounted at many different positions on the transmitter, making it possible to also place the transmitter on a small surface, when needed.
The Multi-bracket (included) provides a lot of extra, versatile mounting possibilities, for example mounting on tripod, magnet bases, or rods to elevate the transmitter.

Laser transmitter XT22 can be used to measure flatness, straightness, squareness, level and parallelism. The laser beam can sweep 360° with a measurement distance of up to 40 metres [130´] in radius. The laser head is super stable, but still easy to turn. No need for locking/unlocking screw.
We have installed electronic precision vials in the XT transmitters. This gives the advantage of faster feedback when levelling and less risk of errors during calibration, because all users see the same angular value (compared with reading spirit levels).
The laser beam can be pointed perpendicular to the flatness plane, within 0.01 mm/m [0.01 mils/inch]. XT22 has a fine turning mechanism for the laser head with a gear ratio of 1:1320, which makes it super easy to point the beam at the detector also on very long distances.
The fiber-coupled laser creates an extremely smooth laser beam profile, free from reflections and irregularities. This means that the laser beam will have very good optical properties in terms of straightness (± 0.003 mm [± 0.12 mils]).
