Abstract
A tachometer assembly for monitoring the rotation of an output shaft for measuring the rotational velocity and position of rotating shafts, and more specifically, to a magneto-resistive tachometer assembly which incorporates a dual purpose cover which, during normal use, fits over the tachometer drum and electronic sensor package to give physical protection to the unit. In a shipping mode, however, the cover is reversed and performs the function of an alignment tool in that a radial gap between the magnetic drum and magneto-resistive sensor may be preset at the factory during assembly of the unit. Reversal of the cover to its normal in use position is done in such a way that the preset radial gap is undisturbed.
