A Technologic Improvement Of The Piezoelectric Fluidic Gyroscope Based On Detecting Element |
| |
| Abstract: | Analysis of the thermo-sensitive performance of piezoelectric fluidic gyroscope shows that defect deficiency can be reduced by a better structural design to increase the thermosensitive performance of platinum wire resistance. Using the arithmetic amplifier circuit as the detecting circuit, the signal from which is designed to be processed by a single-chip and corrected by software, can effectively reduce the nonlinear error of platinum wire resistance. Therefore the combined accuracy rate of the piezoelectric fluidic gyroscope is greatly improved. |
