Pt1000 ndi chotsutsa kutentha cha platinamu, ndipo mtengo wake wotsutsa udzasintha ndi kusintha kwa kutentha. Nambala 1000 pambuyo pa "Pt" imasonyeza kuti mtengo wake wotsutsa ndi 1000 ohms pa 0°C, ndipo mtengo wake wotsutsa ndi pafupifupi 1758.56 ohms pa 200°C. Mtengo wa PT1000 umawonjezeka mofanana pamene kutentha kukukwera. Pt100 nayonso ndi chotsutsa kutentha cha platinamu. Nambala 100 pambuyo pa "Pt" imasonyeza kuti mtengo wake wotsutsa ndi 100 ohms pa 0°C, ndipo mtengo wake wotsutsa ndi pafupifupi 175.86 ohms pa 200°C. Pt500 nayonso ndi chotsutsa kutentha cha platinamu. Nambala 500 pambuyo pa "Pt" imasonyeza kuti mtengo wake wotsutsa ndi 500 ohms pa 0°C, ndipo mtengo wake wotsutsa ndi pafupifupi 879.30 ohms pa 200°C.
Masiku ano, Pt1000 imagwiritsidwa ntchito kwambiri poyesa kutentha mu ma heat meters kapena ma calorimeter. Choyamba, nambala yomaliza ya Pt1000 ndi yayikulu, zomwe zimapangitsa kuti pakhale kulondola kwambiri. Kachiwiri, kuletsa kwa Pt1000 kolowera ndi kwakukulu, ndipo mphamvu yamagetsi yotulutsa imatha kuwonjezeka, zomwe zimapangitsa kuti mphamvuyo ikhale yowonjezereka. Kachitatu, PT1000 ndiyoyenera kuyeza kusintha kwa kutentha kwapakati (chifukwa chake kutentha kukasintha ndi digiri imodzi, kusintha kwa mtengo wotsutsa kumakhala kwakukulu, ndipo dera lotsatira limatha kuzindikira mosavuta). Ponena za kagwiritsidwe ntchito, Pt1000 ndiyonso yosavuta. Mu ntchito zamafakitale, nthawi zambiri, zizindikiro zotsutsa za Pt100 ndi Pt500 zimasinthidwa kukhala zizindikiro za 4-20mA, kenako zizindikirozo zimakonzedwa. Komabe, Pt1000 imayesa mwachindunji chizindikiro chotsutsa.
