so, id like to pick up RPM of a shaft with a prox. 800hz prox, and a normal DC input on a ML1400 can scan at 1kHz (scan time dependent). so with that information, a shaft spinning at say 30rpm, with a trigger wheel attached to it with 60 teeth on it. it would rotate at .5rpm/second. so the prox would be counting 30 teeth in that span. with the 800hz prox, best case scenario it can pulse 800 times/second, the above should work out fine should it not?
now under the same idea but with a higher speed shaft, say 1200rpm. so thats 20rpm/sec, using a trigger wheel with only 30 teeth that would get me 600 teeth per second, still below the 800hz sensor capability no? or would i need to get into using a HSC on ML1400 to actually be able to capture that RPM?
hopefully what i think makes sense and im not completely and totally off base here.
