Sig­nal In­puts for Vi­bra­tion Mea­sure­ment

The input mod­ules on the IfTA plat­form cap­ture sen­sor sig­nals quick­ly and with­out in­ter­fer­ence. The AD4 fam­i­ly of input mod­ules offer the high­est sig­nal qual­i­ty through true 24-bit AD con­ver­sion. Vi­bra­tion phe­nom­e­na can be de­tect­ed syn­chronous­ly with up to 102.4 kHz, on up to 32 chan­nels. These can also be sup­ple­ment­ed with input mod­ules for slow ana­log or dig­i­tal sig­nals. For high­ly ac­cu­rate mea­sure­ment of an­gu­lar mo­men­tum, the AT2 High Speed Timer input mod­ule is also avail­able. Its out­stand­ing pre­ci­sion and ver­sa­til­i­ty was award­ed 2nd place at the messtec + sen­sor mas­ters award 2017.

Mea­sure­ment sig­nals from ex­ter­nal pre-am­pli­fiers or sig­nal con­vert­ers can be con­nect­ed to the AD4 ei­ther as volt­age sig­nals or as cur­rent sig­nals. Like­wise, com­mon in­dus­tri­al stan­dard sig­nals can be ap­plied di­rect­ly by a con­trol sys­tem (±10 V, 0-10 V, 4-20 mA, etc.).

Test Bench­es

The AD4 is also suit­able for test bench­es, e.g. if cus­tom-made or ex­ot­ic pre-am­pli­fiers have al­ready been in­stalled for sen­sors, or if the sen­sor is al­ready di­rect­ly sup­ply­ing a volt­age or cur­rent sig­nal.

Sta­tion­ary In­stal­la­tions

The AD4 and AD4IEPE are pri­mar­i­ly used in per­ma­nent­ly in­stalled in­dus­tri­al ma­chin­ery. The AD4IEPE of­fers all the fea­tures of the AD4 for stan­dard sig­nals (±10 V, 0-10 V, 4-20 mA, etc.) with the ad­di­tion of a switch­able IEPE sup­ply on each chan­nel.

Espe­cial­ly when there are large dis­tances be­tween the con­trol room and the mea­sur­ing site, gal­van­ic iso­la­tion is re­quired - not only for the de­sired sig­nal, but also for the volt­age sup­ply of the sen­sor or charge am­pli­fi­er. IEPE tech­nol­o­gy in­cor­po­rates both into a sin­gle 2-wire cable. Espe­cial­ly in ap­pli­ca­tions with large num­bers of mea­sur­ing lo­ca­tions, IEPE enor­mous­ly sim­pli­fies the in­stal­la­tion ef­fort and mea­sure­ment setup.

This stan­dard is ap­plied to sen­sors such as ac­cel­er­a­tion, force and pres­sure sen­sors or mi­cro­phones and dif­fers in its des­ig­na­tion de­pend­ing on the man­u­fac­tur­er. ICP© (in­te­grat­ed cir­cuit piezo­elec­tric), CCLD© (con­stant-cur­rent line-drive), IsoTron©, DeltaTron© or Piezotron© are some ex­am­ples.

Test bench­es

The AD4IEPE is also rec­om­mend­ed for test bench­es, since gal­van­ic iso­la­tion of the power sup­ply from pre-am­pli­fiers or sen­sors is also ad­van­ta­geous for them: With 2-wire ca­bles, the wiring ef­fort per mea­sur­ing site is ex­treme­ly low, mak­ing wiring easy to man­age and there­fore less prone to er­rors.

Sta­tion­ary In­stal­la­tions

The AD4, AD4IEPE and AD4PS mod­ules are used in in­dus­tri­al plants for long-time mon­i­tor­ing and pro­tec­tion sys­tems. The AD4PS of­fers all fea­tures of the AD4 with the ad­di­tion of a switch­able IEPE sup­ply and volt­age source on each chan­nel. Thus, ac­tive sen­sors and other mea­sure­ment chain com­po­nents such as iso­la­tion am­pli­fiers can be run di­rect­ly.

Espe­cial­ly when there are large dis­tances be­tween the con­trol room and the mea­sur­ing site, gal­van­ic iso­la­tion is re­quired. With the AD4PS this gal­van­ic iso­la­tion per chan­nel is al­ready in­te­grat­ed. With the IEPE sup­ply, a 2-wire line is suf­fi­cient for the sup­ply of the sen­sor, since the sup­ply and the sig­nal are led over the same line. Espe­cial­ly in ap­pli­ca­tions with large num­bers of mea­sur­ing sites, IEPE enor­mous­ly sim­pli­fies the in­stal­la­tion ef­fort and mea­sure­ment setup.

Thanks to the flex­i­ble push-in con­nec­tors, in­stal­la­tion ca­bles can be laid di­rect­ly with­out the need for time-con­sum­ing con­nec­tor as­sem­bly.

Test bench­es and mo­bile mea­sure­ments

The AD4PS is also rec­om­mend­ed for test bench­es and mo­bile mea­sure­ments, since gal­van­ic iso­la­tion is of ad­van­tage here, too. Ad­di­tion­al­ly, de­pend­ing on the mea­sure­ment task, the ap­pro­pri­ate sup­ply of sen­sors and other com­po­nents can be ac­ti­vat­ed and no fur­ther ex­ter­nal com­po­nents are re­quired for this. The mea­sure­ment chains re­main lean and man­age­able and thus less prone to er­rors.

Ser­vice

Ser­vice en­gi­neers are con­front­ed with mea­sur­ing tasks that change on a daily basis. With the AD4Pro you are pre­pared for any type of sen­sor, with­out hav­ing to carry ad­di­tion­al ex­ter­nal am­pli­fiers. In­te­grat­ed am­pli­fiers make sen­sor changes easy.

Re­search

Thanks to the in­te­grat­ed am­pli­fi­er, the sig­nal qual­i­ty is un­beat­able. That is why the Chair of Turbo-ma­chin­ery and Flight Propul­sion at the Tech­ni­cal Univer­si­ty of Mu­nich re­lies on the AD4Pro for its com­pres­sor test bench.

Sig­nal ac­qui­si­tion: Tem­per­a­tures by Means of Ther­mo Ele­ments / Re­sis­tance Ther­mome­ters

TI4

  • Overview
  • Tech­ni­cal spec­i­fi­ca­tions
  • Ex­am­ples of ap­pli­ca­tion

High­lights

  • Mo­d­ule with 4 ana­log tem­per­a­ture mea­sure­ment chan­nels
  • In­di­vid­u­al­ly gal­van­i­cal­ly iso­lat­ed in­puts
  • Pre­cise and low noise tem­per­a­ture mea­sure­ment with a wide se­lec­tion of sen­sors:
    • Ther­mo cou­ples (type B, E, J, K, N, S, R, T) with pre­cise cold junc­tion com­pen­sa­tion per chan­nel
    • Re­sis­tance ther­mome­ters (RTDs) in 2-, 3-, or 4-wire mea­sure­ments
    • Ther­mis­tors
  • In­te­grat­ed sup­pres­sion of mains hum (50 and 60 Hz)

Ad­van­tages of the tem­per­a­ture input card

  • Easy mea­sure­ment of dif­fer­ent tem­per­a­ture sen­sors with only one mea­sure­ment card
  • The in­te­grat­ed cold junc­tion com­pen­sa­tion al­lows an easy and pre­cise mea­sure­ment with ther­mo cou­ples
  • Thanks to the 3- or 4-wire mea­sure­ment in com­bi­na­tion with the built-in com­pen­sa­tion, the TI4 en­sures re­li­able mea­sure­ments also when mea­sur­ing with re­sis­tance ther­mome­ters over long lines

Sig­nal ac­qui­si­tion: Oper­at­ing data with gal­van­ic iso­la­tion

AD16

  • Overview
  • Tech­ni­cal spec­i­fi­ca­tions
  • Ex­am­ples of ap­pli­ca­tion

High­lights

  • Mo­d­ule with 16 ana­log in­puts
  • Four gal­van­i­cal­ly iso­lat­ed zones (zone 1: chan­nel 1-4, zone 2: chan­nel 5-8, ...)
  • Sam­pling rate of 5 Hz @ 24-bit res­o­lu­tion
  • Mea­sure­ment of op­er­at­ing data, e.g. power, flow, ro­ta­tion speed, sup­ply volt­age, etc.
  • Each chan­nel can be con­fig­ured via soft­ware. The mea­sure­ment sig­nals are con­nect­ed on the front via a ter­mi­nal block with push-in (spring) con­nec­tors
  • Each chan­nel pro­vides:
    • 85 dB sup­pres­sion of 50 Hz and 60 Hz

Ap­pli­ca­tion Ex­am­ples

Ideal for record­ing and mon­i­tor­ing op­er­at­ing data and other slow­ly chang­ing sig­nals such as:

  • Power
  • Flow rates
  • Ro­ta­tion­al speeds
  • Sup­ply volt­ages

The IfTA sys­tem can react to mea­sured val­ues at these in­puts in the same way as to val­ues from other mod­ules, e.g. with au­to­mat­ic trig­ger­ing or mes­sages via out­put mod­ules.
