| Abstract: | The structure and signal processing that make use of the natural convection gas in a hermetic chamber pendulum characteristic to sense level posture were researched. The platinum resistance wire was used as heat source, and the natural convection of the gas was produced in a hermetic chamber. The carrier posture signal was getted and disposed by hardware circuit and software compensate technique. The gas pendulum level posture sensor is developed successfully.And its measurement range is ±45°, the non-linearity is less than 1%FS and the resolution less than 0.01°. |
