Sig­nal In­puts for Vibra­tion Meas­ure­ment

Suit­able sup­ple­ment­ary com­pon­ents

• IfTA charge amp­li­fi­er
• IEPE power sup­ply with gal­van­ic isol­a­tion

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.
