Couldn't you just integrate the speed of the cable to get its length?

I've used the "integrate Line Speed" method a few times in web handling applications. I found that it's as accurate as any capstan/encoder method due to the vagaries of stretch/shrinkage and slip. I suppose that it really depends on how accurate you need to be?

It's surprising that's your experience as I've been doing web handling for many years and I have exactly the opposite experience....With web handling, you get all the slippage, as your source of speed integration is typically from large diameter rolls that are driven by a drive.
Allscot, I realize its now several months after the fact, but yesterday I saw a peperl-fuchs sensor that uses the same basic technology an optical mouse uses. It senses material moving past it and outputs 1 pulse per millimeter.

I could not find anything googling for what Alaric mentioned either. It must be a brand new development, perhaps in a trade rag?
