Monitoraggio dell'elevata corrente CC nel settore manifatturiero e nell'industria pesante

In molti settori industriali, i processi produttivi e di produzione di base richiedono l'uso di correnti CC elevate. Esempi tipici includono processi di elettrolisi per l'estrazione di metalli o produzione chimica, processi di rivestimento di metalli o tecnologia di saldatura ad arco. Inoltre, i motori CC sono ancora preferiti in molte applicazioni industriali per la loro facilità di controllo e la coppia costante nell'intero intervallo di velocità.

Perché Knick?
Quando si tratta di misurare in sicurezza tensioni e correnti CC elevate in condizioni difficili, i trasduttori ad alto isolamento di Knick sono la prima scelta. Tensioni fino a 4500 V DC o correnti fino a 20.000 A (tramite shunt) vengono misurate dai trasduttori ad alta tensione con un errore di guadagno inferiore allo 0,3% del valore misurato ed emesse come segnali standard 4...20 mA. A causa dell'isolamento standard a 3 porte e del comportamento stabile di modo comune dei trasduttori shunt, lunghe distanze di trasmissione, elevate differenze di potenziale tra stazioni di misurazione e controllo e forti influenze EMC non rappresentano fonti di interferenza per la trasmissione del segnale.
