Monitoring of condition of machines by recurring measurements of vibration is one of the most effective and reliable method of early prediction of possible failures/prevention of unexpected breakdowns.

It allows to detect early warning signs and helps to stop unscheduled outages, optimize machine performance, and reduce repair time and maintenance costs. The diagram below shows a typical example of the warning signs.

Vibration of machines


The diagram above shows that vibrations are the first warning sign that a machine is prone to failure. This warning sign can provide 3 months of lead time before the actual failure date. Monitoring and analyses of vibration allow to predict the failure early and schedule proper maintenance. 

The machine condition monitoring by measurements and analyses of vibration is applicable to a very wide range of industrial plant, including machine tools, steel, board and paper mills, chemical plants, hospitals, cement ovens, compressors, diesel engines, air-conditioners, ventilation fans and power stations.
