Description

A20230 Trasmettitore di resistenza | Corpo salvaspazio con larghezza di 6 mm

Trasmettitore per potenziometri per il rilevamento della posizione, la misurazione del percorso o l'impostazione del valore nominale in un corpo da 6 mm.

  • Impiego universale
    con potenziometri, sensori di resistenza, teletrasmettitori di resistenza e sensori simili
  • Configurazione intuitiva
    dei parametri di base – semplice, senza strumenti ausiliari, mediante 4 selettori rotativi e 8 interruttori DIP
  • Commutazione del campo calibrata
    Non è più necessaria una complessa regolazione
  • Comoda regolazione
    Punto iniziale e finale regolabili in modo diretto con la funzione di apprendimento premendo semplicemente un tasto
  • Isolamento sicuro
    in conformità alla norma EN 61140 – protezione del personale addetto alla manutenzione e dei dispositivi a valle contro le tensioni elevate non ammesse fino a 300 V AC/DC
  • Elevata precisione
    grazie all'innovativo concetto di circuito
  • Ingombro minimo
    nell'armadio elettrico – armadio modulare con uno spessore di soli 6 mm – maggior numero di trasmettitori per ogni metro di guida di montaggio
  • Montaggio conveniente
    Installazione rapida, comodo collegamento dell'alimentazione elettrica mediante connettori bus per guide di montaggio
  • Garanzia di 5 anni

Compito
In molti settori industriali è necessario rilevare con precisione le posizioni, ad es. di attuatori e trasmettitori del valore di riferimento. In molti casi, sono utilizzate come grandezze di ingresso per controlli, monitoraggi, spegnimenti di sicurezza e simili compiti critici. Di norma, quindi, i requisiti di funzionalità, precisione, flessibilità e sicurezza elettrica sono elevati.

I movimenti rotatori possono essere rilevati con potenziometri come sensori angolari, mentre i movimenti traslatori con potenziometri lineari come sensori di distanza.
Questi e altri sensori forniscono un segnale non elaborato che viene preparato per l'ulteriore elaborazione con l'ausilio di un trasmettitore di resistenza e convertito in scala
in un segnale standard.

Problema
I sensori di posizione comunemente disponibili in commercio hanno valori caratteristici individuali che l'utilizzatore finora doveva utilizzare per l'impostazione lunga e complicata del proprio trasmettitore di resistenza mediante potenziometro.

Inoltre, finora i trasmettitori di resistenza nell'armadio modulare erano molto larghi e occupavano quindi molto spazio nell'armadio elettrico. Per consentire l'utilizzo in tutto il mondo, spesso sono state messe a disposizione più varianti con diverse tensioni di alimentazione.

Soluzione
I trasmettitori di resistenza universali A20230 offrono possibilità di collegamento per tutti i comuni potenziometri per il rilevamento di posizione, percorso e angolo fino a 50 kOhm. Tramite i selettori di codifica e gli interruttori DIP o attraverso una "funzione di apprendimento" possono essere adattati in maniera flessibile dall'utilizzatore al rispettivo compito di misura. L'isolamento a 3 porte con isolamento sicuro secondo la norma EN 61140 fino a 300 V AC/DC garantisce la protezione di persone e impianti e una trasmissione non distorta dei segnali di misurazione. A20230 offre quindi le massime prestazioni nel minor spazio possibile.

L'adattamento del valore iniziale e finale del singolo sensore di posizione è possibile con particolare praticità grazie alla "funzione di apprendimento", semplicemente premendo il tasto sulla parte anteriore del corpo. Per i sensori con valori caratteristici noti all'utilizzatore, la calibrazione può essere eseguita molto facilmente tramite quattro selettori di codifica e otto interruttori DIP.

I compiti di misura speciali possono essere svolti con dispositivi configurati da Knick in base alle specifiche del singolo cliente. Se, ad esempio, si deve escludere una manipolazione o uno scambio, è possibile utilizzare dispositivi impostati senza interruttori.
