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.
