Counter/tachometer circuit?

[Spehro Pefhany]

Yes, I frequently download user guides while researching a product.

But my question was more about whether I correctly understand the definition
of and need for "scaling" as applied to my case?

Thanks,

First you have to be sure you've got the number you want and not the
reciprocal of the number you want, then you can worry about scaling.
Only studying the manual or talking to a sales rep will help with
that.

OK. Thanks!

I have a Shimpo DT-5TG-0 programmable panel mounted tachometer that
will do exactly what you want. Its new/old/stock (never used) $150.
Includes instructions.

Printing equipment such as sheet-fed presses refer to speed in
impressions-per-hour. I want to build a circuit that will display
this number on 5 LED digits.

The sensor will be a simple hall-effect or other sensor that is
triggered up to 4 times a second (maybe less than one, probably not
more than 5).
It's a simple thing to start and stop a timer to calculate the period
of the print cycle, but how to convert that to a meaningful IPH
figure? Is a look-up table or maths done by microcontroller the only
way? Or can some other means be used?
I prefer the non-microcontroller solution, as I haven't yet broached
the PIC [used as generic term] world...
Thanks,
