Title:
VIBRATION MEASURING INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2007/088764
Kind Code:
A1
Abstract:
[PROBLEMS] To enhance output and S/N ratio by regulating the relative movement of a magnet and a coil to within an optimal range and to enhance precision and reliability of a vibration measuring instrument. [MEANS FOR SOLVING PROBLEMS] Amplitude of vibration of a magnet (26) is regulated by stoppers (14, 22) and the lower end face of the magnet (26) does not move beyond the center and the upper end face of a coil (13). The magnet (26) vibrates such that the lower end face thereof reciprocates between the center and the upper end face of the coil (13) at all times, and an accurate cosine wave is outputted from the coil (13) at all times.
