COMPOUND SENSOR FOR MONITORING STATE OF ROTATION DEVICE |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a sensor for monitoring the state of a rotation device to detect the abnormality state. Ž<P>SOLUTION: Concerning a magnet provided with a magnetic field sensor such as an induction coil and a Hall element and a vibration sensor mounted on the magnet, the magnet fixes the vibration sensor on a measured part, and has a role generating a static magnetic field on a rotation part of the rotation device. A compound sensor for monitoring the state achieves vibration signal measurement due to the vibration sensor and measurement detected with the magnetic field sensor providing a dynamic magnetic field on the magnet due to an induction current generated by crossing the inside of the static magnetic field with the rotation part as a single sensor.
