I need to measure multiple elevators and I need to measure the thickness of the cables within the shaft. What's the best way to check for the thickness of the cables?
the device will be moving since it will be measuring the thickness of the entire cable, and I want to automate it as much as possible.
What sensors are best meant for this use case?
More details required!
Is this something that will be permanently installed, to monitor continuously?
Or something for periodic manual inspections?
Or what?
For periodic manual inspections, how about:
How does your question connects with arduino ?
I need something dynamic, it won't be in a single place at all time. its for measuring out an elevator shaft which will be moving up and down.
When you say "elevator" - is that what the British call a "lift" ?
Or some other sort of "elevator"?
Is this a standard requirement in elevators? If so, what do others use?
What are your specifications for cable size, measurement accuracy, speed of movement, etc, etc, ... ?
Doesn't the shaft usually remain stationary...?
If you are responsible for cable thickness (elevator safety), why did you not get proper instructions/education/equipment???
I thought cables should be replaced as soon as some (one) of the small wires inside are broken...
How thick are these alleged cables, and to what to.seance do you need to measure the thickness?
Who or what is moving the device? Doesn't the cable move?

What causes the cables to become thinner?
They probably don't move fast enough to get thinner just because they are moving.

Surely the cables move up and down . If you go in the plant room you can see the cables moving past at a fixed point onto the motor drive you need to study how a lift works . .
I’m guessing this is a school/Uni type project as such a system would probably never be allowed or be able to detect all cable faults .
If the cable has gone “thin” it should have been replaced !!
If it is a school project, I am willing to help... if it is for real life I quit...
i would use a laser and a ldr to measure the thickness of the wire on a wheel
stretching?
Lack of lubrication will cause the strands to move against each other and shed steel molecules. Over time you get thinner cables. Time being many years. So, if the required annual inspection does not measure the cables then eventually there will be problems.
Cable sandwiched between two pulley wheels held together with springs.
Measure the distance between the wheels using a dial gauge with a serial output.
Please be more forthcoming with the project. A cable just above the cabin will ALWAYS be as round as it was when the cable was new. It will never be subject to wear as it NEVER gets to the pulleys nor to the capstan winding the cable.
The cable part that gets wound will never be round because to flattens by the capstan. How then will you measure it's thickness?
Are your cables stretching and getting thinner because of poor quality steel?
What type of elevator are we talking about. I know of several that have cables. Post a picture. Is this used to convey person or persons? What are your tolerances? What is the size of the cable? What is the cable made of?
Team C will win unless teams A and B and D etc. get better advice. Is this a school project?
Any system such as this that I have ever seen is strictly monitored by periodic visual and electrical inspections.
They do not rely on any "automated inspection" system.
And that very reason is why all elevators that may carry people are licensed by some government agency.
