A METHOD AND SYSTEM FOR COMPENSATING A ROD POSITIOA METHOD AND SYSTEM FOR COMPENSATING A ROD POSITION INDICATION SYSTEM FOR NON-LINEARITY N INDICATION SYSTEM FOR NON-LINEARITY

摘要

A method for compensating a rod position indication system for non-linearity comprises the steps of applying an excitation current to a primary of a sensor for inducing a generally linear voltage that is representative of the position of a control rod on a secondary of the sensor. The excitation current includes a first frequency which is sufficient to provide the generally linear output for the sensor. The excitation current is then modified to include a second frequency which is sufficient for providing the generally linear output when the first frequency is insufficient to provide the generally linear output.
