I am trying to choose a wire encoder for my project. So far, I found this wire encoder (see link). Assuming the measurement range of my cylinder is 1 m. Then, with a 10 bit ADC converter of my Arduino Mega2560, I would have a resolution of 0.09cm (= 100cm/1024). But, lets say some cylinder only have a measurement range of 0.5m. Then the resolution would be 0.048 (=50cm/1024).

I can see that I am missing something here, because the resolution of the later case should be worse than the case with the full measurement range 1m. I would be appreciate for any tipps.

Edit:

  • Cylinder's movement range 0~1m enter image description here
  • Wire encoder's measurement range 0~1.25m enter image description here
  • Wire encoder's analog output 0~10v
  • ADC resolution 10 bit
