Pt1000 yog ib lub platinum thermal resistor uas nws tus nqi tsis kam hloov pauv raws li qhov kub thiab txias. Tus "1000" tom qab "Pt" txhais tau tias nws muaj qhov tsis kam ntawm 1000 ohms ntawm 0 ° C thiab kwv yees li 1758.56 ohms ntawm 200 ° C. Qhov tsis kam ntawm PT1000 nce ntxiv tas li thaum qhov kub nce. Pt100 kuj yog ib lub platinum thermal resistor, nrog rau "100" qhia txog qhov tsis kam ntawm 100 ohms ntawm 0 ° C thiab kwv yees li 175.86 ohms ntawm 200 ° C. Pt500, lwm lub platinum thermal resistor, muaj qhov tsis kam ntawm 500 ohms ntawm 0 ° C thiab kwv yees li 879.30 ohms ntawm 200 ° C.
Tam sim no, Pt1000 siv dav rau kev ntsuas kub hauv cov ntsuas kub. Ua ntej, Pt1000 muaj qhov kawm tiav loj dua, ua rau muaj qhov tseeb dua. Qhov thib ob, nws qhov kev nkag siab siab dua tso cai rau qhov hluav taws xob excitation nce ntxiv, txhim kho qhov rhiab heev. Qhov thib peb, PT1000 zoo tagnrho rau kev ntsuas qhov kub me me (txij li qhov hloov pauv kub ib-degree ua rau muaj kev hloov pauv tsis kam loj, ua rau nws yooj yim dua rau lub voj voog tom ntej kom pom). Hauv kev siv, Pt1000 yooj yim dua rau cov neeg siv. Hauv kev teeb tsa kev lag luam, cov teeb liab tsis kam ntawm Pt100 thiab Pt500 feem ntau hloov mus ua 4-20mA tam sim no teeb liab rau kev ua tiav ntxiv, thaum Pt1000 ncaj qha ntsuas cov teeb liab tsis kam.
