Peb feem ntau pom nyias zaj duab xis platinum resistors ua ib hom ntawm fission ntawm ntau yam ntsuas kub. Tus editor ntseeg hais tias txawm hais tias muaj coob tus neeg tau pom nyias-film platinum resistors, lawv kuj yuav tau saib sai sai thiab yuav tsis xyuam xim ntau npaum li cas nyias-film platinum resistors yog. Vim li cas nyias zaj duab xis platinum resistors siv hauv cov ntsuas kub? Niaj hnub no, tus editor yuav piav qhia rau koj tias nyias zaj duab xis platinum resistors yog dab tsi.
Nyias zaj duab xis platinum tsis kam, tseem hu ua nyias zaj duab xis platinum thermistor, yog qhov ntsuas kub ntawm qhov ntsuas kub uas hloov nws cov nqi tsis kam nrog qhov kub thiab txias, yog li saib xyuas qhov ntsuas kub ntawm lub sijhawm. Kev tsim cov thev naus laus zis ntawm nyias zaj duab xis platinum thermistor yog cov txheej txheem tsim khoom tshiab uas hloov cov coils nrog cov thev naus laus zis. Nws yog tsim los ntawm platinum zaj duab xis nrog micrometer thickness thiab nws txuas nrog substrate, thiab qhov ntsuas kub tuaj yeem ncav cuag -50-600 degree .
Cov yam ntxwv ntawm nyias zaj duab xis platinum kuj
Tus nqi siab tsis kam: Tus nqi kuj yog 100 ohms ntawm 0 degree C rau pt100 platinum kuj, thiab 1000 ohms rau pt1000 platinum kuj. Txawm li cas los xij, tus nqi tsis kam ntawm nyias zaj duab xis platinum kuj maj mam txo qis nrog qhov nce ntawm qhov kub thiab txias, ua rau nws haum raws li cov ntsiab lus tseem ceeb ntawm cov ntsuas kub.
Siab rhiab heev: Lub nyias zaj duab xis platinum resistor tuaj yeem teb sai sai rau kev hloov pauv ntawm qhov kub thiab txias, nrog lub sijhawm sib xws ntawm tsuas yog 0.15 vib nas this hauv dej maj mam ntws.
Me me: Sab nraud qhov ntev ntawm nyias zaj duab xis platinum resistors yog me me, nyob rau hauv qhov kev txiav txim ntawm millimeters, ua rau lawv tshwj xeeb tshaj yog haum rau installation nyob rau hauv nqaim qhov chaw, xws li kub ntsuas. Cov ntsuas kub ntawm lawv tus kheej tsis loj heev, yog li nyias zaj duab xis platinum resistors yog qhov tsim nyog.
Kev ruaj ntseg zoo: Raws li cov ntaub ntawv txheeb cais, qhov kev tiv thaiv ntawm nyias zaj duab xis platinum resistor hloov tsawg dua 0.02% tom qab ua haujlwm tas li rau ntau tshaj 1000 teev nyob rau hauv qhov kub thiab txias ntawm 600 degree.
Tsawg tus nqi noj: Nyob rau hauv cov ntaub ntawv ntawm loj-scale automated ntau lawm, nyias-film platinum resistors muaj tsawg tus nqi, uas yog 50% -60% qis dua zoo xws li hlau qhov txhab resistors.
