Inductive Sensing Technology
A Revolution in Sensing
Inductivesensingisanew,contactless,magnet-freetechnologythat
revolutionizessensingbydeliveringbetterperformance,betterreliability,and
greaterexibilitythanexistingsolutions,atalowersystemcost.TheLDC1000is
theworld’srstinductance-to-digitalconverterthatenablesinductivesensing.
Better Performance and Reliability
TheLDC1000provides16-bitresonanceimpedanceand24-bitinductance
values,enablingsub-micronresolutioninposition-sensingapplications.Inductive
sensingisalsoimmunetonon-conductiveinterferencessuchasdirtanddust
anditsupportsremotesensorplacement,makingitwell-suitedforextremeand
harshenvironments.
