Linearity Compensation of Air Level Posture Sensor

Abstract:

In order to improve linearity of output signal of air level posture sensor, this article do the research about linearity to output signal based in the operation function of single chip of MSC1214, uses the ORIGIN software to process experiment data to get the linearity curve. The result indicates that misalignment of sensor drops to ≤1% in full scale scope, linearity between output voltage and the input angle has the enormous improvement, depressing the influence caused by angle approximation and improving the measurement accuracy of air level posture sensor.
