Exact distance (Stroke) measurement

[MitsM83]

We have a machine that has a huge brake and clutch. MX measures the travel of this with a dial indicator every month for a PM. It only moves a few MM. Occasionally the shims need adjusted or pads changed.

I have been dreaming up a way to make the PLC do this every cycle then the PM could be backed up to a quarterly or semi-annual or something just to check the sensors.

Any one have any ideas, LDVT?

Try a MDT rod from Balluff or Temposonic. They have resolutions down to 1 micron. You will need to get a SSI card for you PLC.

I'll check that out. Thanks.
