Pt1000 ndi chotsutsa kutentha cha platinamu chomwe mtengo wake umasiyana malinga ndi kutentha. "1000″ pambuyo pa "Pt" zikutanthauza kuti chili ndi kukana kwa 1000 ohms pa 0°C ndi pafupifupi 1758.56 ohms pa 200°C. Kukana kwa PT1000 kumawonjezeka pang'onopang'ono pamene kutentha kukukwera. Pt100 ndi chotsutsa kutentha cha platinamu, ndipo "100" imasonyeza kukana kwa 100 ohms pa 0°C ndi pafupifupi 175.86 ohms pa 200°C. Pt500, chotsutsa china cha kutentha cha platinamu, chili ndi kukana kwa 500 ohms pa 0°C ndi pafupifupi 879.30 ohms pa 200°C.
Pakadali pano, Pt1000 imagwiritsidwa ntchito kwambiri poyesa kutentha mu zoyezera kutentha. Choyamba, Pt1000 ili ndi kutsiriza kwakukulu, zomwe zimathandiza kulondola kwambiri. Kachiwiri, kuletsa kwake kwakukulu kolowera kumalola mphamvu yowonjezera yotulutsa mpweya, zomwe zimawonjezera kukhudzika. Kachitatu, PT1000 ndi yabwino poyesa kusintha pang'ono kwa kutentha (popeza kusintha kwa kutentha kwa digiri imodzi kumabweretsa kusintha kwakukulu kwa kukana, zomwe zimapangitsa kuti dera lotsatira lizindikirike mosavuta). Ponena za kugwiritsa ntchito, Pt1000 ndi yosavuta kugwiritsa ntchito. M'malo opangira mafakitale, zizindikiro zotsutsa za Pt100 ndi Pt500 nthawi zambiri zimasinthidwa kukhala zizindikiro zamphamvu za 4-20mA kuti zigwiritsidwe ntchito, pomwe Pt1000 imayesa mwachindunji chizindikiro chotsutsa.
