    • A system includes a housing disposed within a fluid having a fluid flow. A first member is located substantially external to the housing and is directly exposed to the fluid flow and lengthwise positioned transverse to the direction of the fluid flow. The first member is configured to vibrate independently of the housing responsive to direct exposure to the fluid flow. A coil is coupled to one end of the first member. The coil is disposed within the housing and shielded from direct fluid flow. A magnet is disposed within the housing separate from and adjacent to the coil. The magnet is shielded from direct fluid flow. Magnetic flux from the magnet induces an electric current through the coil responsive to relative motion between the magnet and the coil caused by vibration of the first member.
    • 一种系统包括设置在具有流体流动的流体内的壳体。 第一构件基本上位于壳体外部,并且直接暴露于流体流动并且横向于流体流动方向纵向定位。 第一构件被配置为响应于直接暴露于流体流动而独立于壳体振动。 线圈耦合到第一构件的一端。 线圈设置在壳体内并且不受直接流体流动的屏蔽。 磁体设置在与线圈分离并且与线圈相邻的壳体内。 磁体屏蔽了直接的流体流动。 响应于由第一构件的振动引起的磁体和线圈之间的相对运动,来自磁体的磁通量通过线圈引起电流。
