I-Pt1000 yi-resistor ye-thermal yeplatinum, kwaye ixabiso layo lokuxhathisa liya kutshintsha ngokutshintsha kobushushu. Inani eli-1000 emva kwe-“Pt” libonisa ukuba ixabiso layo lokuxhathisa yi-1000 ohms kwi-0°C, kwaye ixabiso layo lokuxhathisa limalunga ne-1758.56 ohms kwi-200°C. Ixabiso lokuxhathisa le-PT1000 liyanda ngokufanayo njengoko ubushushu bunyuka. I-Pt100 ikwayi-resistor ye-thermal yeplatinum. Inani eli-100 emva kwe-“Pt” libonisa ukuba ixabiso layo lokuxhathisa yi-100 ohms kwi-0°C, kwaye ixabiso layo lokuxhathisa limalunga ne-175.86 ohms kwi-200°C. I-Pt500 ikwayi-resistor ye-thermal yeplatinum. Inani eli-500 emva kwe-“Pt” libonisa ukuba ixabiso layo lokuxhathisa yi-500 ohms kwi-0°C, kwaye ixabiso layo lokuxhathisa limalunga ne-879.30 ohms kwi-200°C.
Kule mihla, i-Pt1000 isetyenziswa kakhulu ekulinganiseni ubushushu kwiimitha zobushushu okanye iikhalorimitha. Okokuqala, inani lokugqiba le-Pt1000 likhulu, nto leyo ebangela ukuchaneka okuphezulu. Okwesibini, i-input impedance ye-Pt1000 iphezulu, kwaye i-excitation voltage inokwandiswa, ngaloo ndlela iphucula uvakalelo. Okwesithathu, i-PT1000 ifanelekile ekulinganiseni utshintsho lobushushu oluncinci (isizathu kukuba xa ubushushu butshintsha ngedigri enye, utshintsho kwixabiso lokumelana lukhulu, kwaye isekethe elandelayo inokuyibona ngokulula). Ngokuphathelele ukusetyenziswa, i-Pt1000 ikwalula ngakumbi. Kwizicelo zentsimi yemizi-mveliso, ngokubanzi, imiqondiso yokumelana ye-Pt100 kunye ne-Pt500 iguqulwa ibe yimiqondiso yangoku ye-4-20mA, kwaye emva koko imiqondiso iyacutshungulwa. Nangona kunjalo, i-Pt1000 ilinganisa ngokuthe ngqo isignali yokumelana.
