    The number of pulses per revolution will give you the number.

    What is the output of the tachometer, digital (pulses) or analog?

    Can you provide a part number for the tach? Maybe we can find a datasheet for it.

    How many peaks on the sine wave per rotation? Turn the shaft by hand and use a meter.
