An embodiment of the invention generally pertains to a method of
compensating for temperature variations in an eddy current sensor signal.
The method may include the steps of receiving an initial signal from an
eddy current sensor (ECS) in response to a conductive element passing the
ECS and sensing an ECS temperature and an ECS board temperature. The
method may also include determining a subset of correction coefficients
based on the ECS temperature and the ECS board temperature and
determining a temperature correction factor from the subset of correction
coefficients. The method may then compute a temperature corrected signal
from the initial signal and the temperature correction factor.
