<p>A process device for coupling to an industrial process for use in monitoring or controlling the process includes a device housing (16) configured to physically couple to the industrial process. A coil of wire (100) is mounted to the housing and a magnet (104) is configured to move through the coil of wire. The relative movement of the magnet is responsive to vibrations (72) in the industrial process. Such relative movement induces an electrical current in the coil of wire. Electrical circuitry in the housing includes an input to receive the electrical current from the coil of wire.</p> |
