Kind Code:
A1
Abstract:
The present invention pertains to a vibration monitoring device that monitors vibrations produced in a contact section between a liquid and a machine such as a rotary machine and/or auxiliary equipment of said machine. A vibration monitoring device (30) comprises: a vibration sensor (31) that detects vibrations and outputs said vibrations as vibration data; a transmitter (33) that wirelessly transmits the vibration data; a vibration generator (34) that generates electric power with the vibrations and supplies said electric power to the vibration sensor and the transmitter; and a waterproof unit case (38) that houses the vibration sensor, the transmitter, and the vibration generator. The waterproof unit case (38) is structured so as to prevent a liquid from infiltrating an internal space of the waterproof unit case, and the vibration sensor, the transmitter, the vibration generator, and the waterproof unit case make up a unified vibration detection unit.
