DIAL INDICATOR MADE WITH OLD MANOMETER!

[machining 4 all]

After a few measurements, the results follow. I inserted five eccentric displacements at three different pressures. It can be concluded from the graph that, under less pressure, the pointer has a linear displacement. As pressure increases, displacements become more unstable and not proportional. Probably at higher pressures the pointer was more sensitive to surface roughness, and at lower pressures it was not as accurate. However, the ecentricity points inserted were identified by the manometer and it was possible to center the surface. Thus, it can be said that this assembly fulfills its qualitative function and is a low cost option when there is no dial indicator for any reason.
