A Sensitive Technique of Airflow Omnibearing Level Posture

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
