Combined with the measurement components from PRÜFTECHNIK including a Bluetooth® module, the tab@lign app composes a wireless laser shaft alignment system for tablets and smart phones. The app is dedicated to standard shaft alignment including quick alignment checks on machines such as a motor-pump combination.

Equipped with the PRÜFTECHNIK patented single-laser technology, and offering a high system dependability, tab@lign delivers accurate and repeatable measurement results.

Key features include:

• 3 steps to alignment
Enter dimensions, rotate shafts and display measurement result.

• Bluetooth® communication
The PRÜFTECHNIK measurement equipment provides high-accuracy measurement data to the Apple device through the Bluetooth® module for a convenient data transmission.

• Active Clock measurement
During shaft rotation, measurements are automatically taken at 3 sensor positions. A shaft rotation of only as little as 70° is required. The activated electronic inclinometer eliminates possible user error for intelligent and precise alignment.

• Result and Live Move
Both horizontal and vertical coupling and foot results are automatically calculated and displayed. The graphics show the machine position and the arrows the necessary feet corrections. During Live Move, tab@lign monitors the horizontal changes live on the screen, continuously updating the adjustments.

• Soft foot
Measure, correct and save soft foot results.

• Reporting
Measurement results can be immediately shared via email in a clear single-page graphical report to facilitate and shorten the alignment cycle time.

In Demo mode, the app can simulate measurement scenarios using the mobile device’s position sensor.

PRÜFTECHNIK participates in the “Made For iPhone” (MFi) program and the measurement components together with the Bluetooth® module are certified by Apple Inc.

This app requires the measurement components from PRÜFTECHNIK. They can be purchased separately at:

Ratings and Reviews

Mr tab@lign ,

Great app

Best tablet based alignment tool on the market

Positive input.

Yes, it is lacking certain functions. That doesn't mean it's useless. If you understand Alignments, then you understand the simplicity that this App provides. Any negativity should be discarded. It is simply Better than 'All the rest'.

Targets would be a Valuable Addition to this.

At this price, I can afford to put this in all of my Mechanics hands, regardless of location.

Useless Demo mode

The demo mode is useless. It records 1reading. If you waste 5 minutes fighting it you can get it to record a second point. Unfortunately you need a minimum of 3 points before you can go on to see any of the results screens in order to evaluate the product.
What would be so hard with having demo mode demonstrate taking the readings? I have wasted a full hour try to evaluate the system and have been stymied by a non-functional demo mode. I can only assume that the entire program is just as poorly written
