E540 Simple and efficient shaft alignment tool

Easy-Laser® E540 is a very powerful shaft alignment system, with the ideal balance between performance and price. Program that guides step-by-step with both icons and text makes the system very easy to use for everyone, regardless of prior knowledge. The E540 system includes measurement programs for horizontal machines, vertical machines and alignment of machine trains with three machines. The measuring units are pre-mounted for rapid machine set-up. Start with the measuring units positioned anywhere through 360 ° around the shaft, then take any three readings down to 20° in-between. Then adjust the machine with the live-values in both horizontal and vertical directions. A PDF report is generated automatically when the measurements are saved. Simple and efficient!

Technology that gives the best performance in demanding industrial environments

The shaft alignment system has a large 5.7", bright colour display that clearly shows all the steps of the measurement. The measuring units have TruePSD-technology, which gives unlimited resolution. Twin laser beams, twin PSDs and twin inclinometers give you superb control of the measurement in all situations. The measuring units are incredibly compact featuring Bluetooth® Wireless technology, an integrated rechargeable battery and large 30 mm TruePSD detectors. This means that they are easy to install on most types of machines, even where there is limited space. The wireless technology gives you full freedom of movement around the machine that is to be aligned. Display unit, measuring units and fixtures are all very robust for the highest accuracy in demanding industrial environments. 

Large expansion possibilities

It is possible to connect two very useful accessories to the system. With Vibrometer E285 it is possible to check the vibration level and bearing condition of the machine. Using E170 BTA you can check and align sheaves and pulleys with digital precision. You can document the measurements for vibration checks and belt alignment in the same way as for the normal shaft alignment programs. There is also a wide range of accessory brackets, such as magnet bases, axial magnet brackets and brackets for non-rotating shafts. The transportation case is equipped with recessed compartments for the accessories, which means that you can carry everything in one case.

With the barcode reader the user can save many key operations where all machine dimensions, tolerances and compensation values are entered in one single operation, and the measurement can be started directly. At the first measurement, save the downloaded machine data and attach the barcode label to the machine. The barcode reader is an accessory.
