Hi Guys,
Has anyone looked at the pot on a Young 05103, it is also 10k and looks something similar albeit at a hefty price ($180 approx)
Young Part #05134 POTENTIOMETER 10K, 1/4% LIN, CONDUCTIVE PLASTIC
Clarkey
Texas Electronics is not much better as their
replacement 10K pot is $185.70. Not sure what else would be needed to make it work with other loggers or displays but they also sell a
4-20 mA signal conditioner. I'll probably eventually look into everything required for my purposes and share my findings here in due time.
Clarkey,
I know that the Young potentiometer is a 5 degree dead zone, and I have several in a box out in the shed (-3 right now) which I got new with a bunch of other Young stuff on eBay a few years ago.
I have the little Texas Electronics weather vane potentiometer on a shelf in a little box so it will be 'easy' enough to compare size and get an idea about fit.
I cannot recall how the pots were afixed to the base, if it was just tight nuts on a bracket, or if there were screws, which would present a mounting challenge, but nothing that a small dab of hot glue or the super flexible silicone seal would suffice. It isn't going to the LaGrange point after initial launch. (Which, by the way, I was amazed at the initial jolt that the Ariane booster took when the solids lit and it jumped off the pad).
The potentiometer is panel mounted. I'm sure if worse came to worse you could drill out the mounting hole on the plate within the sensor housing and squeeze it in there. Only problem is figuring out how to couple the pot and vane shaft together. At least with the one I have, there is a coupling that goes onto the pot shaft and allows the bar on the vane shaft to recess within so its not physically attached but "pushed around." I'll attach a drawing of what I mean below because explaining that mechanical situation is not easy.

There's a set screw in the coupling thing too but I believe it is on the opposite side of the cut in.
Again, if you were to put a new pot in there, either a size change or complete redesign of the coupling apparatus would be needed.
Edit: Clarky, the R. M. Young potentiometer might work but you'd have to fenagle a mounting situation because the casing is not panel fixed. I'm not sure what the dimensions of the brass coupling are but depending on shaft thickness it may fit or only require minor resizing. Like Dale said something along the lines of glue would probably suffice because I'd doubt there are major vibrations in that thing if any at all.
