ABSTRACT:
System for providing a digital indication of the load on a scale, utilizing a relative position transducer to produce two output signals which vary between fixed levels in response to incremental displacements of the output indicator of the scale. The two signals are phase encoded in that one of the signals leads the other, depending upon the direction of displacement. The two signals are processed to determine the occurrence and direction of each increment of displacement, and the count in a digital counter is incremented or decremented in response to each increment according to the direction of the displacement.
