MULTIDIGIT COUNTING WHEEL MECHANISM FOR A VOLUME-MEASURING INSTRUMENT

摘要

Absolute encoder for measuring instrument with mechanical counting whee l mechanism consisting of five sensors (20), which are mounted in one plane perpendicularly to the counting mechanism axle (15), for each counting wheel (12) and a code (21), which produces a digital rotary angle signal with a resolution of 12.degree., on the counting wheel (12). The counting wheel mechanism can be read off visually in conventional manner and the encoder does not increase the torque required for the drive of the counting mechanism.
