Platinum tsis kam, tseem hu ua Platinum thermal kuj, nws tus nqi tiv taus yuav hloov nrog qhov kub. Thiab cov neeg tsis kam lees ntawm Platinum tsis kam yuav nce tsis tu ncua nrog qhov ntsuas kub.
Platinum tsis kam tuaj yeem muab faib ua PT100 thiab PT1000 series khoom, pt100 txhais tau tias nws tsis kam hais txog 0 ℃ yog 1000 ohms.
Platinum tsis kam muaj qhov zoo ntawm kev co kev cai tiv thaiv, zoo ruaj khov, kev ntsuas kub, kev tiv thaiv qhov kub thiab lwm yam siab ntsuas kub.
PT100 lossis PT1000 Tawv Kub Sensors yog cov sensors ntau heev hauv kev lag luam txheej txheem. Txij li thaum lawv yog ob qho RTD sensors, cov tsiaj ntawv luv RTD sawv rau "kev ntes kub". Yog li ntawd, nws yog qhov ntsuas kub thiab txias qhov twg tsis kam nyob ntawm qhov ntsuas kub; Thaum qhov kub hloov pauv, qhov tsis kam ntawm lub sensor tseem yuav hloov pauv. Yog li ntawd, los ntsuas ntsuas qhov tsis kam ntawm RTD sensor, koj tuaj yeem siv RTD sensor los ntsuas qhov kub.
RTD Sensors feem ntau yog ua los ntawm platinum, tooj liab, alloys alloys lossis ntau tus hlau oxides, thiab pt100 yog ib qho ntawm cov sensors feem ntau. Platinum yog cov khoom siv feem ntau rau RTD sensors. Platinum muaj ib tug ntseeg tau, rov ua dua thiab linear kub tiv thaiv kev sib raug zoo. RTD sensors ua los ntawm platinum yog hu ua prts, lossis "platinum ua hluav taws xob." Feem ntau feem ntau siv prt sensor hauv kev lag luam txheej txheem yog PT100 Sensor. Tus lej "100" nyob rau hauv lub npe qhia tau ib qho kev tiv taus ntawm 100 ohms ntawm 0 ° C (32 ° F). Ntau ntxiv tom qab. Thaum PT100 yog cov platinum feem ntau RTD / PRT sensor, muaj ob peb lwm tus, xws li PT25, PT50, PT500, thiab PT1000. Lub ntsiab sib txawv ntawm cov sensors yooj yim tau 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 me me me vim tias nws cuam tshuam txog kev tawm tsam ntawm lwm qhov kub. Yog tias nws yog PT1000 (385), qhov no txhais tau tias nws muaj qhov kub faib ntawm 0.00385 ° C. Thoob ntiaj teb, feem ntau cov ntawv yog 385. Yog tias cov coefficient tsis tau hais, nws yog feem ntau 385.
Qhov sib txawv ntawm PT1000 thiab PT100 tsim nyog muaj raws li hauv qab no:
1. Qhov tseeb yog txawv: Cov tshuaj tiv thaiv rhiab ntawm PT1000 yog siab tshaj qhov ntawm PT100. Qhov ntsuas kub ntawm PT1000 hloov los ntawm ib qib, thiab cov nqi tiv taus nce lossis txo qis txog 3.8 ohms. Qhov ntsuas kub ntawm PT100 hloov pauv los ntawm ib qib, thiab cov nqi tsis kam lees paub txog 0.38 Ohms tau yooj yim rau 0.38 Ohms tau yooj yim rau kev ntsuas kom yog, yog li qhov raug yog tseem siab dua.
2. Qhov ntsuas kub muaj ntau yam sib txawv.
PT1000 yog haum rau cov ntsuas me me; PT100 yog tsim nyog rau ntsuas ntau cov ntsuas kub ntau.
3. Tus nqi sib txawv. Tus nqi ntawm PT1000 yog siab tshaj qhov ntawm PT100.
