Il existe de nombreuses normes pour \u00e9valuer la qualit\u00e9 des \u00e9l\u00e9ments chauffants. Comment pouvons-nous simplement tester la qualit\u00e9 d'un \u00e9l\u00e9ment chauffant dans notre travail et notre vie de tous les jours ? Aujourd'hui, je vais vous expliquer comment utiliser un multim\u00e8tre pour tester la qualit\u00e9 d'un \u00e9l\u00e9ment chauffant.<\/p>\n\n\n\n
R\u00e9glez le multim\u00e8tre sur la plage de 1K ohm et placez les deux sondes sur les deux extr\u00e9mit\u00e9s du c\u00e2ble chauffant.<\/p>\n\n\n\n
Si le multim\u00e8tre affiche une certaine valeur, cela signifie que le fil chauffant fonctionne normalement. Notez la valeur de la r\u00e9sistance. Si aucune valeur n'est affich\u00e9e, cela signifie que le fil chauffant est cass\u00e9 et que l'\u00e9l\u00e9ment chauffant ne peut pas \u00eatre utilis\u00e9.<\/p>\n\n\n\n
En utilisant les formules 220250\/valeur de la r\u00e9sistance ou 380<\/em>380\/valeur de la r\u00e9sistance, vous pouvez calculer la puissance. Si la puissance calcul\u00e9e s'\u00e9carte de moins de 5% de la puissance nominale, l'\u00e9l\u00e9ment chauffant est bon.<\/p>\n\n\n\n Si l'\u00e9cart de puissance est important, cela indique que le processus de fabrication n'est pas conforme aux normes. Si la valeur de la puissance est excessivement \u00e9lev\u00e9e, par exemple sup\u00e9rieure \u00e0 10 000, cela signifie qu'il y a un court-circuit dans le c\u00e2ble chauffant, ce qui peut provoquer un incendie ou d'autres dysfonctionnements \u00e9lectriques. Dans ce cas, l'\u00e9l\u00e9ment chauffant ne doit pas \u00eatre utilis\u00e9.<\/p>\n\n\n\n GlobalQT est sp\u00e9cialis\u00e9 dans la fabrication de \u00e9l\u00e9ments chauffants \u00e0 quartz<\/a>.
