Platinum kuj, tseem hu ua platinum thermal kuj, nws tus nqi kuj yuav hloov nrog kub. Thiab tus nqi tsis kam ntawm platinum kuj yuav nce tsis tu ncua nrog qhov nce ntawm qhov kub thiab txias.
Platinum kuj tuaj yeem muab faib ua PT100 thiab PT1000 series cov khoom, PT100 txhais tau hais tias nws qhov kev tiv thaiv ntawm 0 ℃ yog 100 ohms, PT1000 txhais tau tias nws qhov tsis kam ntawm 0 ℃ yog 1000 ohms.
Platinum kuj muaj qhov zoo ntawm kev vibration tsis kam, zoo stability, siab raug, siab siab kuj, thiab lwm yam. Nws yog dav siv nyob rau hauv kev kho mob, lub cev muaj zog, kev lag luam, kub xam, satellite, huab cua, kuj xam thiab lwm yam high precision kub khoom.
PT100 los yog PT1000 kub sensors yog heev sensors nyob rau hauv cov txheej txheem kev lag luam. Txij li thaum lawv yog ob qho tib si RTD sensors, cov ntawv luv RTD sawv cev rau "tsis kam ntsuas kub ntsuas". Yog li ntawd, nws yog qhov ntsuas kub uas qhov kev tiv thaiv nyob ntawm qhov kub thiab txias; Thaum qhov kub hloov pauv, qhov tsis kam ntawm lub sensor kuj yuav hloov. Yog li, los ntawm kev ntsuas qhov tsis kam ntawm RTD sensor, koj tuaj yeem siv RTD sensor los ntsuas qhov ntsuas kub.
RTD sensors feem ntau yog ua los ntawm platinum, tooj liab, npib tsib xee alloys lossis ntau yam hlau oxides, thiab PT100 yog ib qho ntawm cov khoom siv ntau tshaj plaws. Platinum yog cov khoom siv tshaj plaws rau RTD sensors. Platinum muaj qhov txhim khu kev qha, rov ua dua thiab cov kab hluav taws xob tiv thaiv kev sib raug zoo. RTD sensors ua los ntawm platinum hu ua PRTS, los yog "platinum resistance thermometers." Qhov feem ntau siv PRT sensor nyob rau hauv cov txheej txheem kev lag luam yog PT100 sensor. Tus lej "100" nyob rau hauv lub npe qhia txog qhov tsis kam ntawm 100 ohms ntawm 0 ° C (32 ° F). Ntxiv rau qhov ntawd tom qab. Thaum PT100 yog platinum RTD / PRT sensor ntau tshaj plaws, muaj ob peb lwm tus, xws li PT25, PT50, PT200, PT500, thiab PT1000. Qhov sib txawv tseem ceeb ntawm cov sensors no yooj yim twv: qhov no yog qhov tsis kam ntawm lub sensor ntawm 0 ° C, uas tau hais hauv lub npe. Piv txwv li, PT1000 sensor muaj qhov tsis kam ntawm 1000 ohms ntawm 0 ° C. Nws tseem yog ib qho tseem ceeb kom nkag siab txog qhov kub thiab txias coefficient vim tias nws cuam tshuam qhov tsis kam ntawm lwm qhov kub. Yog tias nws yog PT1000 (385), qhov no txhais tau tias nws muaj qhov kub thiab txias ntawm 0.00385 ° C. Thoob ntiaj teb, feem ntau version yog 385. Yog hais tias tus coefficient tsis tau hais, nws feem ntau yog 385.
Qhov txawv ntawm PT1000 thiab PT100 Resistors yog raws li nram no:
1. Qhov tseeb yog qhov sib txawv: Cov tshuaj tiv thaiv rhiab heev ntawm PT1000 yog siab dua li ntawm PT100. Qhov kub ntawm PT1000 hloov los ntawm ib tug degree, thiab tus nqi kuj nce los yog txo los ntawm 3.8 ohms. Qhov kub ntawm PT100 hloov los ntawm ib tug degree, thiab tus nqi kuj nce los yog txo los ntawm 0.38 ohms, obviously 3.8 ohms yog yooj yim dua los ntsuas qhov tseeb, yog li qhov tseeb kuj yog siab dua.
2. Qhov ntsuas kub ntau yam txawv.
PT1000 yog haum rau me me ntsuas kub ntsuas; PT100 yog qhov tsim nyog rau kev ntsuas qhov ntsuas kub ntau.
3. Tus nqi sib txawv. Tus nqi ntawm PT1000 yog siab dua li ntawm PT100.
