Esistono molti standard per valutare la qualit\u00e0 degli elementi riscaldanti. Come possiamo verificare semplicemente la qualit\u00e0 di un elemento riscaldante nel nostro lavoro e nella nostra vita quotidiana? Oggi vi spiegher\u00f2 come utilizzare un multimetro per testare la qualit\u00e0 di un elemento riscaldante.<\/p>\n\n\n\n
Impostare il multimetro sulla gamma di 1K ohm e posizionare le due sonde su entrambe le estremit\u00e0 del filo riscaldante.<\/p>\n\n\n\n
Se il multimetro visualizza un determinato valore, significa che il filo riscaldante funziona normalmente. Prendere nota del valore della resistenza. Se non viene visualizzato alcun valore, significa che il filo di riscaldamento \u00e8 interrotto e che l'elemento riscaldante non pu\u00f2 essere utilizzato.<\/p>\n\n\n\n
Utilizzando le formule 220250\/valore di resistenza o 380<\/em>380\/valore della resistenza, \u00e8 possibile calcolare la potenza. Se la potenza calcolata si discosta di meno di 5% dalla potenza nominale, l'elemento riscaldante \u00e8 buono.<\/p>\n\n\n\n Se la deviazione di potenza \u00e8 elevata, indica che il processo di produzione \u00e8 inferiore agli standard. Se il valore di potenza \u00e8 eccessivamente alto, ad esempio superiore a 10.000, significa che c'\u00e8 un cortocircuito nel cavo di riscaldamento, che potrebbe causare un incendio o altri malfunzionamenti elettrici. In questo caso, l'elemento riscaldante non deve essere utilizzato.<\/p>\n\n\n\n GlobalQT \u00e8 specializzata nella produzione di prodotti di alta qualit\u00e0 elementi riscaldanti al quarzo<\/a>.
