Abstract:
1. An apparatus for receiving a wireless signal and driving a conventional tachometer, said apparatus comprising: a receiver responsive to the wireless signal, said wireless signal including a series of pulses corresponding to a rotational speed of a device, said receiver having a receiver output with a receiver output level corresponding to a signal level of said wireless signal, said receiver output level limited to an alternating current peak-to-peak voltage of one half of an operating voltage of said receiver; and a signal conditioner connected to said output of said receiver, said signal conditioner having a conditioned output with a conditioned output level substantially equal to said operating voltage of said receiver wherein said conditioned output is sufficient to drive a tachometer, said signal conditioner including one of an amplifier or a transformer wherein said amplifier has a gain sufficient to drive said conditioned output of said amplifier to an output level substantially equal to said operating voltage of said receiver, said transformer has a turns ratio sufficient to produce a conditioned output level substantially equal to said operating voltage of said receiver, and said transformer is connected as a step up transformer.
