L\u00e4mmityselementtien laadun arvioimiseksi on olemassa monia standardeja. Miten voimme yksinkertaisesti testata l\u00e4mmityselementin laatua p\u00e4ivitt\u00e4isess\u00e4 ty\u00f6ss\u00e4mme ja el\u00e4m\u00e4ss\u00e4mme? T\u00e4n\u00e4\u00e4n jaan kanssasi, miten yleismittaria k\u00e4ytet\u00e4\u00e4n l\u00e4mmityselementin laadun testaamiseen.<\/p>\n\n\n\n
Aseta yleismittari 1K ohmialueelle ja aseta kaksi anturia l\u00e4mmityslangan molempiin p\u00e4ihin.<\/p>\n\n\n\n
Jos yleismittari n\u00e4ytt\u00e4\u00e4 tietty\u00e4 arvoa, se tarkoittaa, ett\u00e4 l\u00e4mmityslanka toimii normaalisti. Merkitse vastusarvo muistiin. Jos n\u00e4yt\u00f6ss\u00e4 ei n\u00e4y mit\u00e4\u00e4n arvoa, se tarkoittaa, ett\u00e4 l\u00e4mmitysjohdossa on katkos, eik\u00e4 l\u00e4mmityselementti\u00e4 voi k\u00e4ytt\u00e4\u00e4.<\/p>\n\n\n\n
K\u00e4ytt\u00e4m\u00e4ll\u00e4 kaavoja 220250\/vastuksen arvo tai 380<\/em>380 \/ vastusarvo, voit laskea tehon. Jos laskettu teho poikkeaa alle 5% nimellistehosta, l\u00e4mmityselementti on hyv\u00e4.<\/p>\n\n\n\n Jos tehopoikkeama on suuri, se osoittaa, ett\u00e4 valmistusprosessi on puutteellinen. Jos tehoarvo on liian suuri, esimerkiksi yli 10 000, se tarkoittaa, ett\u00e4 l\u00e4mmitysjohdossa on oikosulku, joka voi johtaa tulipaloon tai muihin s\u00e4hk\u00f6isiin toimintah\u00e4iri\u00f6ihin. T\u00e4ss\u00e4 tapauksessa l\u00e4mmityselementti\u00e4 ei saa k\u00e4ytt\u00e4\u00e4.<\/p>\n\n\n\n GlobalQT on erikoistunut korkealaatuisten kvartsil\u00e4mmityselementit<\/a>.
