Does anyone have history with measuring linear distances?

[Cobikys]

I have a project am working on, I need advise on sensors applicable to linear measurement

Measuring what over what distance?

You need to state your application, the question is too broad.
e.g. for machine tool use there is linear scales.

Bosch laser distance measurement - used one of these for indoor data logging.

Wow, I posted a link, it puts in the preview. Cool.

Just examples, likely many brands out there.

Or were you after callipers or a micrometer?

I want to measure a strings lenght in real time, like if the strings lenght reduce it senses it and vice versa

You mean - "how long is a piece of string?"

ROFL

So how long is this piece of string!
Are we talking shrinkage? Or is it being reeled in?
Still NEI!

It's been reeled in

Put one turn around a pulley of known diameter and measure the rotation of that pulley.

Yes, I think we have.
