Akagwiritsidwa ntchito poyang'anira mafakitale, masensa amatha kujambula momwe zinthu zilili. Zisonyezo za masensa zimagwiritsidwa ntchito mkati mwanjirayo kuti azitsatira mosalekeza kusintha komwe kumayang'aniridwa. Zizindikiro zonse za digito ndi analogi zimatha kuchitika.
Nthawi zambiri mphamvu yamagetsi yamagetsi kapena mtengo wapano umapangidwa womwe umagwirizana molingana ndi zosintha zomwe zikuyang'aniridwa.
Kusintha kwa siginecha ya analogue kumafunika ngati njira zodzichitira zokha zimayenera kusungitsa nthawi zonse kapena kukwaniritsa zomwe zafotokozedwa. Izi ndizofunikira kwambiri pakugwiritsa ntchito ma process automation. Zizindikiro zamagetsi zokhazikika zimagwiritsidwa ntchito popanga uinjiniya. Analogi yokhazikika mafunde / voteji 0(4)...20 mA/ 0...10 V adzikhazikitsa okha monga muyeso wakuthupi ndi zowongolera zosintha.
