A Sensitive Technique of Airflow Omnibearing Level Posture

Abstract:

Article Preview

The paper firstly introduced the sensitive mechanism of micromachined airflow omnibearing level posture. There is a non-closure annulus heat source in the airtight space, and around the heat source, there are eight parallel heat resistance wire composed omnibearing level posture sense organ. Signal processing circuit is composed by pre-signal circuit and digital circuit, to obtain voltage, omnibearing signal synthesis and resolution compensation of omnibearing tile angle signal. It is testified that: resolution<0.1°,the scope of azimuth is 360°,the scope of tile angle is 20°. The sensor is not only in small size but also in simply crafting. It is good in sensitive organ’s output consistency, and suitable for mass production.
