I have come to the conclusion that in my training efforts I cannot rely on just one motor alone and will have to have several. I would like to sense and display RPM to class. Display has to be visible from 10' away. I am not too concerned with tolerance 5% should be OK. Mostly what I will be showing is change in speed - possibly very quick which elimiates digital readout.
The tach readout I have is 14 Volt and 98 mA. I have tach generator which will require me to make up a voltage divider.
I would like to see if a prox type pickup could be used as a sensor. In theory this would be adaptible to any motor and driven load setup.
I like Lovejoy couplings and think they will give me a lot of versatility. These are matched 3 jaw units so in theory I have 6 gaps to measure with. The question comes up with the spider (plastic) will it "add" more gaps ie give me a total of 12??
Will my idea of sensing off lovejoy work?
