Abstract
An absolute position sensor having a detector with a plurality of Wiegand wire sensors that each have a pair of Hall sensors bracketing or straddling the Wiegand wire used by a processor in interpolating relative ratios of signals from the bracketing Hall sensors in not only providing increased fine position determination between magnets but also providing coarse position count increment or decrement verification. Such an absolute position sensor provides increased fine position determination accuracy while also enhancing increment and/or decrement error prevention and/or correction during position sensor operation.
