I'm looking at several in Travers catalog and I can't tell how they measure the distance traveled except that I don't see that stupid 'tire' so I'm guessing they use some kind of linear gradient to measure with...
Even the 2-axis DRO's are expensive...  |
You must have looked at something pretty old, the modern ones work just like digital calipers, with a magnetic strip and a reading unit. I took a chance and bought some cheap ones (here's the 12" model:
