Electronic Tilt Compensation for Diaphragm Based Pressure Sensors

摘要

System, apparatus and method for providing corrective sensor outputs, particularly when a sensor is subject to gravitational or acceleration effects. A sensor and accelerometer may be operatively coupled to a processor, wherein the processor receives inputs from both. The processor receives the sensor signals and determines the gravitational or acceleration effects on the sensor from the accelerometer signals. Based on these, the processor determines a correction factor that is applied to the sensor signals to provide improved and more accurate sensor outputs.

1. A circuit-based method for producing a corrected sensor signal, storable in a tangible medium, comprising the steps of:
receiving at least one sensor signal, said sensor signal representing an environmental characteristic; receiving one or more accelerometer signals, said accelerometer signals correlating to different orientations of a sensor producing the sensor signal; and producing the corrected sensor signal, wherein said corrected sensor signal is based at least in part on processing the at least one sensor signal and the one or more accelerometer signals.
