PCT No. PCT/CN95/00062 Sec. 371 Date Apr. 25, 1997 Sec. 102(e) Date Apr. 25, 1997 PCT Filed Jul. 28, 1995 PCT Pub. No. WO96/04531 PCT Pub. Date Feb. 15, 1996An absolute amplitude sensor device for measuring absolute vibrations comprising a non-contact displacement sensor, in particular, an eddy-current sensor and a vibrator. Said vibrator is comprised of a number of inertial mass pieces, springs, a damper and a housing. The inertial mass piece is levitated in said housing by means of said springs and damper. The output signal of said device is directly proportional to the amplitude of the object to be measured. The number of said inertial mass pieces is N. It is a single-vibrator when N equals 1 and a multi-vibrator when N equals 2 to 20. |
