This is quite simple. A schmidt trigger chip will work, as long
as the signals are swinging across 2.5 V above ground. But, the
reason they use sine wave output is to allow interpolation of
the scale. So, this scale may have a very coarse basic resolution,
which is all you will get with the direct conversion.
