Applications

Distance-measuring, inductive sensors offer many application possibilities. A basic distinction is made between direct distance measurements/position feedback and indirect, specific measurements.


Tecnologia

I sensori induttivi di distanza (AlphaProx) si basano sullo stesso principio di funzionamento degli interruttori di prossimità induttivi. I sensori di questo tipo generano un campo elettromagnetico ad alta frequenza in prossimità della loro stessa superficie. Se in quest’area viene a trovarsi un oggetto di metallo, il campo elettromagnetico varia in funzione della distanza del materiale e delle dimensioni dell’oggetto. Questa variazione viene rilevata dal sensore e trasformata in un segnale di uscita. Nei sensori AlphaProx standard questa conversione è solo analogica. In questo modo i sensori possono raggiungere elevate velocità di misurazione, un’eccellente ripetibilità e un’alta risoluzione con un basso disturbo del segnale.
