Easy-Laser® XT770 - Shaft alignment
Easy-Laser® XT770 Shaft is the perfect starting point for most of your alignment jobs on rotating machinery. It’s a versatile and robust shaft alignment system capable of handling complex machinery setups.
The system provides precise alignment for horizontal and vertical/flange-mounted rotating machinery. It supports alignment of machine trains and includes features like base twist and bearing play checks. 2 axis PSD:s allow simultaneous vertical and horizontal adjustments.
By adding accessories, the system can also:

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).
