Abstract
Methods and systems are disclosed in which the errors caused by thermal expansion in magnetoresistive position transducers are reduced by predicting the physical alterations over temperature between centerline-to-centerline distances of particular magnetoresistive sensors or components within a magnetoresistive array and also between such an array and a magnet being sensed caused by thermal expansion.
