Fisher model 3582 D-ring control valve positioner (manual demonstration)

Here, we see a demonstration of the Fisher model 3582 valve positioner, disconnected from the valve. This way, it is a bit easier to see the interaction of the input and feedback mechanisms, specifically how each affects the baffle/nozzle gap.

Really good explination on the principles of operation. Your videos are great teaching tools, Thanks again.

@BuilderRoss You are very welcome. It's really hard to find any kind of explanatory tutorial -- video or otherwise -- for free on the internet. I decided about a year ago to start posting short videos to YouTube for my students, and so far the response from people all over the world has been really positive.

Seems so simple, until your teacher unbalances the beam, and messes with the zero and span :@

Agreed. This is a very clear and succinct explanation.

These are great videos to knock loose the cobwebs for working instrument mechanics. Thank you so much for continuing to post them.
