New Video From VibrAlign Explains 3 Dial Indicator Shaft Alignment Concepts

Share Article

The video, available on VibrAlign’s YouTube channel, explains three dial indicator concepts: Total Indicator Value, the Validity Rule and True Position Sensing.

zero the indicator...roll it 180’ll then be reading true position

Digital laser shaft alignment systems evolved from earlier analog methods which employed dial indicators. The concepts that are applied to perform alignments with dials form the basis for the way digital laser systems work. It is important, therefore, for practitioners of alignment, whether they use dials or lasers, to have a good understanding of dial indicator concepts.

The new video walks the viewer through 3 concepts:

  •     Total Indicator Value or TIR
  •     The Validity Rule
  •     True Position Sensing or TPS

While TIR and the Validity Rule have been known for quite some time, VibrAlign has taken these concepts a step further and created what the company calls “True Position Sensing.” In the video Patrick Lawrence, VibrAlign Trainer, demonstrates TPS and explains that “you can zero the indicator at any position, roll it 180 degrees, halve the value and you’ll then be reading true position”.

VibrAlign’s discovery of True Position Sensing led to the development of a whole new process for performing shaft alignments, which VibrAlign calls the “Verti-Zontal Compound Move”. This new way to perform alignments can result in precision shaft alignments being completed in record time.

VibrAlign started in 1983 as a vibration and alignment service organization and later became a distributor of equipment which, appropriately, equipped our team to better serve. VibrAlign is America’s exclusive distributor of Fixturlaser® – the manufacturer of the only touch screen tool available with 3D animation and sensor safeguard against sunlight. For thirty years, VibrAlign has been growing across the country. Today we proudly operate out of local offices in every major region.
