The apparatus consists of vibration sensor, power unit, one-chip computer, infrared-sensing proximity switch and display. It is easy to use and high in measuring and analyzing exactitude with wide range of application.

It makes it possible to take real-time measurement of vibration of rotary machines caused by imbalance of rotators, discrepancy of axis, abrasion of antifriction and sleeve bearings, etc. and trace faults in them.

And it has one-side or two-sides balancing functions, so as to balance rotators weighing from kilograms to tens of tons on the spot.

The apparatus has been already introduced to Namhung Youth Chemical Complex, Sunchon Cement Complex and other industrial establishments to prove effective in lengthening the serviceable life of machines.
