Long-term Meas­ure­ment and St­or­age of Vibra­tions

Vibra­tions in con­tinu­ous op­er­a­tion

The safety of ma­chines that are con­tinu­ously in op­er­a­tion, such as gas-fired power plants, is of the ut­most im­port­ance to the op­er­at­ors. In order to guar­an­tee the ne­ces­sary safety, a mon­it­or­ing and pro­tec­tion sys­tem for vi­bra­tion ana­lys­is and mon­it­or­ing is es­sen­tial. Espe­cially when vi­bra­tions occur sporad­ic­ally, long-term meas­ure­ments can be quite in­form­at­ive. However, dur­ing op­er­a­tion over a long peri­od of time, a large amount of data is gen­er­ated, which leads to the fol­low­ing con­flict.

Per­form­ance versus Pre­ci­sion

The po­ten­tial con­flict with long-term vi­bra­tion data

On the one hand, due to the clar­ity, all data of the vi­bra­tion be­ha­vi­or over the en­tire peri­od should be quickly ana­lyz­able in order to en­sure a high re­act­iv­ity of the sys­tem.  On the other hand, the data set must be avail­able in a high res­ol­u­tion in order to un­der­stand the cor­rel­a­tions of the vi­bra­tion be­ha­vi­or. The un­der­ly­ing con­flict is there­fore to find the right com­prom­ise between data quant­ity and ac­cur­acy when meas­ur­ing vi­bra­tion over a long peri­od of time.

Our solu­tion for Long-term meas­ure­ment and stor­age

A mon­it­or­ing sys­tem with a large stor­age ca­pa­city in con­junc­tion with an ana­lys­is soft­ware with which large amounts of data can be ana­lyzed quickly.

The IfTA sys­tems in com­bin­a­tion with the ana­lys­is soft­ware IfTA TrendView­er en­able a very simple hand­ling of large amounts of data, as they are gen­er­ated for ex­ample in long-term tests of com­pon­ents. The ac­tu­al con­tra­dic­tion between large amounts of data (com­put­ing ef­fort) and fast ana­lys­is is solved in a very el­eg­ant way. Depend­ing on the pur­pose of the ana­lys­is, the data can be viewed in dif­fer­ent modes. In order to cover the en­tire peri­od of time, it is suf­fi­cient to dis­play the data with a lower res­ol­u­tion, whereby if re­quired, it is pos­sible to zoom to cer­tain points with the highest res­ol­u­tion. Thus, very large amounts of data for long-term vi­bra­tion ana­lys­is can be pro­cessed un­com­prom­isingly.
