Ideal Transfer Function

Mathematically, the Ideal Transfer Function is a straight line, independent of temperature, passing through the ideal Offset point with a slope equal to the ideal Full Scale Span over the operating pressure range.

This basic linear function offers end users the advantage of applying a very simple algorithm to interpret the digital output and convert it to something meaningful for their applications. Any deviations in this Ideal Transfer Function, including those occurring over time and exposure to environmental conditions, manifest themselves as sensor errors.

All pressure sensors, no matter how expensive they are, no matter what materials they are made from, or how precisely and accurately they were originally calibrated in the factory, are susceptible to experiencing some level of change in Offset.
