VIBRATION AMPLIFIER, AND VIBRATION AMPLIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To detect fine vibration in a broad band using an existing vibration sensor.SOLUTION: A vibration amplifier 200 is disposed between a detector 100 for detecting the acceleration and a detection object (pipe 500) so that the vibration of the detection object can be propagated to the detector 100. The vibration amplifier 200 has a plurality of resonance frequencies.SELECTED DRAWING: Figure 1
