Vi­bra­tion Mea­sure­ment with Argus Eyes

Ar­gusOMDS: Mon­i­tor­ing and Pro­tec­tion Sys­tem for your Ap­pli­ca­tion

If mea­sured vari­ables such as tem­per­a­ture, pres­sure, speed, etc. can no longer cap­ture the cur­rent state of a com­bus­tion or a ro­tat­ing sys­tem with suf­fi­cient ac­cu­ra­cy, then the only way is to lit­er­al­ly take a look through "X-ray glass­es" - in other words, to iden­ti­fy high­ly com­plex vi­bra­tion pat­terns.

This is the fastest way to iden­ti­fy sub­op­ti­mal sys­tem man­age­ment or ma­chine uti­liza­tion. You can­not pro­tect your tech­nol­o­gy even more ef­fi­cient­ly against over­load/un­der­load and harm­ful events. The Argus Os­cil­la­tion Mon­i­tor­ing Di­ag­nos­tic Sys­tem (Ar­gusOMDS) is a gener­ic so­lu­tion for dy­nam­ic vi­bra­tion phe­nom­e­na. This means: Si­mul­ta­ne­ous ac­qui­si­tion and eval­u­a­tion of vi­bra­tion and op­er­at­ing data.

  • Mea­sure­ment
  • Anal­y­sis
  • Mon­i­tor­ing
  • Pro­tec­tion
  • Sim­ple in­te­gra­tion into ex­ist­ing con­trol sys­tems (field­bus, ana­log, dig­i­tal)
  • Crit­i­cal op­er­at­ing states are avoid­ed and im­por­tant pa­ram­e­ters are sig­nalled to the con­trol room
  • On­line vi­su­al­iza­tion on mul­ti­ple client PCs
  • Real-time ca­pa­ble pro­tec­tion and con­trol func­tions
  • Univer­sal ap­pli­ca­tions: Sta­tion­ary gas tur­bines, com­bus­tion cham­bers, turbo sets, test bench­es, com­pres­sors, blades, gears, bear­ings, mo­tors
  • Com­mon ap­pli­ca­tions: Com­bus­tion vi­bra­tions, tor­sion­al, struc­tural, rotor & shaft vi­bra­tions
  • Op­tion­al­ly with ther­moa­cous­tic early warn­ing sys­tem IFTA PreCur­sor

What makes Ar­gusOMDS unique?

Ad­van­tages of the mon­i­tor­ing and pro­tec­tion sys­tem

  • Proven pro­tec­tion con­cept for max­i­mum sys­tem safe­ty
  • 24/7 for sev­er­al years record­ing of mea­sure­ment and op­er­at­ing data through in­tel­li­gent ag­gre­ga­tion (glos­sary) and stor­age of com­pressed data
  • In­te­grat­ed anal­y­sis soft­ware IFTA TrendView­er for real-time vi­su­al­iza­tion of mea­sure­ment re­sults and si­mul­ta­ne­ous anal­y­sis (live anal­y­sis dur­ing mea­sure­ment)
  • In­for­ma­tive il­lus­tra­tion of fre­quen­cy spec­tra of long-term mea­sure­ments as spec­tro­gram - from a bird's eye view
  • Flex­i­ble trig­ger man­age­ment (in­ter­nal/ex­ter­nal source) to store spe­cif­ic mea­sure­ment points
  • Early warn­ing sys­tem for com­bus­tion dy­nam­ics avail­able
  • Ef­fi­cient iden­ti­fi­ca­tion of ir­reg­u­lar long-term phe­nom­e­na through so­phis­ti­cat­ed long-term data stor­age con­cepts
  • Au­tonomous long-term mon­i­tor­ing: In the event of power fail­ure, the sys­tem restarts au­to­mat­i­cal­ly and con­tin­ues to record data re­li­ably
  • Risk min­i­miza­tion through fast reg­u­la­tion and in­ter­ven­tion be­fore dam­age oc­curs
  • High­ly flex­i­ble input mod­ules, such as AD4pro
  • The pro­tec­tion in the IFTA Ar­gusOMDS sys­tem is based on an PC-in­de­pen­dent dig­i­tal sig­nal pro­ces­sor (DSP) and thus en­sures 24/7 undis­turbed op­er­a­tion - pre­con­di­tion for real-time ca­pa­ble pro­tec­tion sys­tems

The Gener­ic So­lu­tion for Dy­nam­ic Phenom­e­na

The IFTA Ar­gusOMDS has been de­vel­oped es­pe­cial­ly for the mon­i­tor­ing and vi­bra­tion anal­y­sis of the fol­low­ing com­po­nents:


  • Com­bus­tion cham­bers
  • Ro­tors
  • Com­pres­sors
  • Blades
  • Gear­box­es/Bear­ings
  • Engines

It is pre­des­tined for small and large sta­tion­ary gas tur­bines, steam tur­bine gen­er­a­tor sets and other com­po­nents used in the in­dus­try and in power plants. Thanks to the op­ti­mal co­or­di­na­tion of hard­ware and soft­ware, the IFTA Ar­gusOMDS is easy to op­er­ate. Dy­nam­ic data and op­er­at­ing data are record­ed si­mul­ta­ne­ous­ly. This as­sures an un­com­pli­cat­ed as­sign­ment of the vi­bra­tion to the ap­pro­pri­ate op­er­at­ing points. Con­se­quent­ly, the cause can be eas­i­ly clar­i­fied in con­text. Con­tin­u­ous and ef­fi­cient data record­ing en­ables un­fore­seen events to be eval­u­at­ed at a later point in time: A fur­ther ad­van­tage when iden­ti­fy­ing caus­es and find­ing so­lu­tions. The IFTA Ar­gusOMDS also of­fers si­mul­ta­ne­ous on­line vi­su­al­iza­tion of all data on sev­er­al client PCs.

Prod­ucts in use: Ar­gusOMDS Sys­tem, DA8 out­put mod­ule, anal­y­sis soft­ware TrendView­er

Siemens En­er­gy op­er­ates an ultra-mod­ern test cen­ter, the Clean En­er­gy Cen­ter (CEC) near Ber­lin. There, gas-tur­bine com­bus­tors are run­ning under re­al­is­tic con­di­tions. In order to learn from these test mea­sure­ments the IFTA Ar­gusOMDS sys­tem is in place:

  • Flex­i­bil­i­ty and ef­fi­cien­cy on the test-bench
  • Con­sol­i­da­tion of all data streams from dif­fer­ent sources allow the anal­y­sis of
    com­plex re­la­tion­ships
  • Up to 10 test en­gi­neers can mon­i­tor on­line data streams at the same time

Prac­ti­cal Ap­pli­ca­tion IFTA Ar­gusOMDS

 Mon­i­tor­ing of com­bus­tion dy­nam­ics

Per­fect­ly Matched Com­po­nents in the Ar­gusOMDS Sys­tem


Flex­i­ble in­puts/out­puts

  • Flex­i­ble com­bi­na­tion of dif­fer­ent IFTA input and out­put mod­ules, ana­log or dig­i­tal
  • Dy­nam­ic sig­nals can be record­ed with the AD4 fam­i­ly input mod­ules
  • For the mea­sure­ment of op­er­at­ing data such as power, flow, ro­ta­tion speed, sup­ply volt­age the input mod­ule AD16 is avail­able
  • For tor­sion­al vi­bra­tions the input mod­ule AT2 is avail­able
  • For tem­per­a­ture mea­sure­ments the input mod­ule TI4 is avail­able
  • Input mod­ules can be up­grad­ed at any time and thus en­able ac­qui­si­tion of a wide va­ri­ety of data
  • Pro­tec­tion tasks can be han­dled with our out­put mod­ules RelOut16 and DA8. The DA8 out­put mod­ule can pro­vide sen­sor sig­nals as buffered out­puts for other sys­tems

Sim­pli­fied in­te­gra­tion

  • The IFTA Ar­gusOMDS sys­tem is based upon a mod­u­lar hard- and soft­ware ar­chi­tec­ture. Such flex­i­bil­i­ty al­lows to adapt mea­sure­ment, anal­y­sis and mon­i­tor­ing to vary­ing ma­chine types and cus­tomer spe­cif­ic ap­pli­ca­tions
  • Sim­ple com­mu­ni­ca­tion with con­trol sys­tems, whether ana­log or dig­i­tal. By trans­mit­ting all mon­i­tored pa­ram­e­ters, the con­trol sys­tem of the ma­chine pre­vents crit­i­cal op­er­at­ing states
  • With the mod­ules Profibus and Profinet, the IFTA Ar­gusOMDS sys­tem can be eas­i­ly in­te­grat­ed into field­bus en­vi­ron­ments. Two re­dun­dant bus in­ter­faces en­sure high re­li­a­bil­i­ty
  • Cur­rent sta­tus and mon­i­tor­ing vari­ables for con­trol rooms and other sys­tems are pro­vid­ed via OPC

Real-time Pro­tec­tion

  • The heart of the IFTA Ar­gusOMDS sys­tem is the DSP (dig­i­tal sig­nal pro­ces­sor) pro­vid­ing a real-time sig­nal anal­y­sis and re­sponse. In con­trast to Win­dows-based so­lu­tions, this en­ables the pro­cess­ing of al­go­rithms/anal­y­sis/cal­cu­la­tions and sig­nal­ing, which is re­quired in in­dus­tri­al en­vi­ron­ments for real-time pro­tec­tion sys­tems
  • Op­ti­mized al­go­rithms en­sure short anal­y­sis times and live vi­su­al­iza­tion with the in­te­grat­ed anal­y­sis soft­ware IFTA TrendView­er
  • If you do not re­quire a real-time pro­tec­tion func­tion, we rec­om­mend the mea­sure­ment sys­tem IFTA Dy­naMaster

In­te­grat­ed data anal­y­sis

  • The anal­y­sis soft­ware IFTA TrendView­er is an in­te­gral part of the IFTA Ar­gusOMDS sys­tem
  • On- and off­line anal­y­sis in one pro­gram
  • In­tu­itive op­er­a­tion
  • Pow­er­ful vi­su­al­iza­tion
  • High-per­for­mance large scale data pro­cess­ing
  • The ad­van­tage of using IFTA Ar­gusOMDS sys­tem and IFTA TrendView­er in com­bi­na­tion is a va­ri­ety of pre-cal­cu­lat­ed data: Most im­por­tant ex­am­ple is the fre­quen­cy spec­tra cal­cu­lat­ed live per chan­nel with up to 6400 lines
