Magnetic Markers on Steel Cable
Magnetic Markers on Steel Cable
(OP)
I was wondering if anyone new where I could find some information on a system which I have heard exists, that magnetises sections of a wire-line cable (Steel Cable). For example magnetises a small section on the cable every 10ft. The cable is then winched in and out of a muddy hole in the ground and apparently you can use hall effect sensors to measure the number of 10ft sections that are either going into or out of the borehole (Well).
Any help would be appreciated. If more explanation is required then please do not hesitate to ask.

I had such an overwhelming response for this question.........he he.
Anyway, I have since designed a system that can magnetically mark and un-mark steel geophysical logging cable at various intervals (wireline / oil & gas exploration / Minerals exploration / Borehole logging). I have also designed a circuit to read the magnetic mark on the cable (Very important too
If anyone needs anymore information on it or has a use for it. Let me know.

What I meant was some sort of simple roller or sheave that your cable runs past(follower), which turns, and counts how many feet have gone by in either direction.

We have already sold a few of them in the minerals industry. Although our budget and management never let us continue working on it to make the cable marker Automatic. Although I don't perceive that making this unit mark the cable automatically to be a big job, we just need the go ahead from management to do it.
At the moment to use the system, you have to mark the cable manually. For example, spool 100 meters off the winch and press a button to mark the cable.
Let me know what you think.
