Description

Resistenze di shunt | Elevata capacità di sovraccarico | Immuni ai campi esterni

Misurazione affidabile di correnti continue fino ai kA con elevata precisione.

  • Misurazione accurata e stabile a lungo termine della corrente continua
    attraverso resistenze di shunt/resistenze in derivazione

  • Per correnti fino a 15 kA
    Programma standard fino a 8 kA

  • Bassa tensione di shunt / possibilità di realizzare tipi di custodia di dimensioni ridotte
    grazie a speciali isolatori di shunt

  • Precisione dello shunt:
    classe 0,5 a scelta classe 0,2

  • Isolatore di shunt / trasmettitore con errore di guadagno 0,1 %

  • Elevata resistenza al sovraccarico
    senza errore di misura residuo

  • Nessuna interferenza dai cavi vicini
    grazie al principio di misura

  • Isolamento galvanico tra unità di potenza e controllo
    fino a 3,6 kV di tensione di lavoro / 15 kV di tensione di prova

  • Conversione in segnali standard
    ±20 mA, ±10 V, da 4 a 20 mA

  • MTBF di 96 anni
    per l’intero sistema di misurazione della corrente

  • Garanzia di 5 anni

Le resistenze di shunt Maconic si basano su un'esperienza pluriennale nella progettazione e produzione di questo tipo di resistenze. Sono realizzate con cura e con materiali di alta qualità. Le barre di resistenza sono realizzate in manganina, una speciale lega di manganese-rame-nichel, che consente di ottenere un coefficiente di temperatura estremamente basso. Il dimensionamento e la struttura meccanica sono stati scelti per garantire un riscaldamento moderato fino al raggiungimento della corrente nominale.

Le resistenze di shunt e i relativi amplificatori di isolamento shunt raggiungono un’ottima stabilità a lungo termine, in modo da garantire l’accuratezza specificata per periodi di applicazione abituali di molti anni. I picchi di corrente non generano un offset o una deriva. I dispositivi di protezione basati sulla misurazione della corrente beneficiano proprio dell’affidabilità e della stabilità a lungo termine della misurazione, raggiungendo in tal modo un comportamento particolarmente sicuro.
