Vi­bra­tion Mea­sure­ment with High­ly Flex­i­ble In­puts

For ap­pli­ca­tions with chang­ing sen­sors

Nowa­days, very high de­mands are placed on mea­sure­ment tech­nol­o­gy, in par­tic­u­lar vi­bra­tion mea­sure­ment tech­nol­o­gy. The pre­ci­sion and the right tim­ing de­ter­mine the safe­ty of plants and sys­tems. One es­sen­tial com­po­nent of the sys­tems are the sen­sors. In forms of pres­sure, ac­cel­er­a­tion, strain and tem­per­a­ture sen­sors, they pro­vide the en­tire in­for­ma­tion flow for sub­se­quent analy­ses. How­ev­er, most vi­bra­tion mea­sur­ing in­stru­ments cur­rent­ly re­quire a sep­a­rate input mod­ule for each type of sen­sor, as well as suit­able charge am­pli­fiers and power sup­plies. Nor­mal­ly, the mea­sure­ments in­volve dif­fer­ent mea­sured vari­ables under dif­fer­ent am­bi­ent con­di­tions re­quir­ing dif­fer­ent sen­sor types and there­fore many input mod­ules. In ad­di­tion, the man­u­al con­fig­u­ra­tion of all ex­ter­nal com­po­nents and the in­di­vid­u­al mod­ules poses chal­lenges to the op­er­a­tors of the mea­sure­ment sys­tems.
