Easy-Laser® XT770 - Shaft alignment and geo applications
Easy-Laser® XT770 Shaft is the most powerful of our Generation XT laser alignment systems. The 360° Live feature gives you even more possibilities to perform advanced adjustments. With XT770 you can carry out the following:
With Easy-Laser XT770 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 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, part of the XT Alignment app, allows you to keep track of machine movement over time. 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.
With XT770 GEO you will be able to take flatness and straightness measurements according to established standards like ISO and ANSI. The kit includes the versatile laser transmitter XT20 plus a magnet base with rotatable head for geo measurements.
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.
The featured programs below are the most common used with this system. Please click here for a complete overview of possibilities.
The user interface is intuitive and guide 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.
For measurement and alignment of vertically and flange mounted machines.
Build your own machine train with theoretically as many machines as you like. You can pick the reference machine manually, or let the program choose one that will minimize the need for adjustments.
For alignment of cardan/offset mounted machinery. (Requires additional Cardan bracket kit.)
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.
Makes it possible to keep track of machine movement over time. Thus you can check for e.g. thermal expansion and pipe strain issues.
With this program you can check the flatness of foundations and frames, using two rows of points, 2 to 8 points per row. Separate laser transmitter required. (Requires Geo Kit).
Program to measure flatness/twist of, for example, machine foundation, machine tables, etc.
With our program for measuring straightness, you can easily measure long shafts, rolls, bearing journals, bases, overhead rails, machine structures etc. You will be able to get the result for both the horizontal and vertical alignment, graphically as well as digitally. The program automatically calculates different Best-fit results. (Requires Geo Kit)
Use the M and S measuring units included to measure as with digital dial gauges, but with laser precision and the possibility to document the measurement result. Another application is to check shaft radial play (bearing play).
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.)
Diagnose vibration level, unbalance, misalignment and looseness. (Requires the XT280 accessory.)
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.
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!
The result table shows how well your readings repeat and lets you save comments for each one.
The software can adjust to machine designs of all types such as those with two pairs of feet, three pairs of feet, and feet in front of the coupling, etc.
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.
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.
The swap view function allows you to adjust the position of the motor on screen to correspond with the position of the machine in front of you, making it easier to understand adjustment directions.
Adjust both vertically and horizontally at the same time with measuring units in any position.
Adjust with live values also when measuring units are positioned up to 44° from absolute V and H position.
The adjustment guide helps you decide optimum adjustment by simulating shimming and move. For programs Horizontal and Machine train.
Choose from different 3D machines to portray your machinery on either side of the coupling.
The mirror view function allows you to adjust the position of the motor on screen to correspond with the position of the machine in front of you, making it easier to understand adjustment directions.
Assign a specific code to a specific machine, then use the built-in camera of your device to open assigned file and settings. (Note: camera resolution requirements applicable.)
Save measurement files as templates, with machine data and settings, to quickly start measurements.
Lock any pair of feet on the machine. Used when aligning base-bound or bolt-bound machines.
Choose method depending on coupling type: short flex or spacer shaft.
Your latest measurement is always available, automatically saved.
Sign-on screen to verify your job. The signature is saved with the PDF file.
The app includes a searchable Users Manual which opens the right chapter depending where in the process you are. This makes it quick and easy to find the answer to your user questions.
