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.

sta­tion­ary in­stall­a­tions

The eco­nom­ic­al AD4 is primar­ily used in sta­tion­ary in­stalled in­dus­tri­al ma­chinery. 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.).

Ser­vice

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

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.

Ser­­vice

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

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.

Test­ing

The Siemens Clean En­ergy Center for burn­er tests in gas tur­bines in Ber­lin is using the AD4Pro to sig­ni­fic­antly re­duce com­plex­ity in their meas­ure­ment chain, thereby mak­ing fast and error-free con­fig­ur­a­tion changes easy.

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.

    • Thermo ele­ments (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 thermal ele­ments
  • 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

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 4-8, ...)
  • Samp­ling rate of up 20 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
    • Voltage input ±10 V dif­fer­en­tial
    • Cur­rent input 0...20 mA single-ended

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.
