Resonant flow sensor and uses and production methods for the same
Abstract:
The invention relates to a flow state sensor (10) for detecting a flow state at a body (16) that may be impinged on by a flow (12). A flow state sensor (10) that is of a simple construction and that is simple to evaluate is characterized in accordance with the invention by at least one frequency detecting device (20) for detecting at least one predefined frequency characteristic of the flow state. The frequency detecting device (20) has at least one oscillation element (22; 22a, 22b, 22c) excitable to resonant oscillatory movement (30) by a flow (12) and having a resonant frequency or natural frequency adapted to the predefined frequency characteristic, especially corresponding to the predefined frequency characteristic. Uses of the flow state sensor (10) in a flow measuring device (62) and in a flow measuring method, and an advantageous production method for the flow state sensor (10) are also proposed.
Abstract(Chinese):

本发明涉及一种用于检测可能被流动（12）撞击的主体（16）处的流动状态的流量状态传感器（10）。 根据本发明，具有简单结构且简单评估的流状态传感器（10）由至少一个用于检测流动状态的至少一个预定频率特性的频率检测装置（20）来表征。 频率检测装置（20）具有至少一个振荡元件（22; 22a，22b，22c），该振荡元件（22; 22a，22b，22c）可通过流动（12）激励到谐振振荡运动（30），并具有适应预定频率特性的谐振频率或固有频率 ，特别是对应于预定义的频率特性。 还提出了流量测量装置（62）中的流量状态传感器（10）和流量测量方法的使用以及用于流动状态传感器（10）的有利的生产方法。
