Digital rod position indication system and method

A rod position indication system, comprising:

• a first set of coils and a second set of coils disposed in an alternating arrangement;
• a first data encoder unit connected to each of the first set of coils, wherein the first data encoder unit is configured to generate a first reference signal and first position data;
• a second data encoder unit connected to the each of the second set of coils, wherein the second data encoder unit is configured to generate a second reference signal and second position data;
• and
• a processing circuit in signal communication with the first and second data encoder units, where the processing circuit is configured to:
• generate a logic comparison of the first and second reference signals;
• generate a logic signal based on the first position data and the second position data;
• and
• perform a logic operation on the logic signal and a result of the logic comparison.
