Dab tsi yog qhov sib txawv ntawm cov lag luam platinum tooj liab thermal ua hauj lwm thiab cua sov thermal kuj kub txog kub?

Txawm hais tias Armored Thermal resistors tau dav siv hauv kev lag luam, lawv daim ntawv thov raug txwv los ntawm lawv qhov ntsuas kub. Qhov ntsuas kub ntsuas ntawm cov thermal resistors yog raws tus yam ntxwv uas cov nqi tiv thaiv ntawm tus neeg saib xyuas lossis cov teeb meem hloov nrog kub. Nws muaj ntau yam zoo, xws li tej thaj chaw deb sib pauv ntawm cov teeb meem hluav taws xob, kev sib txuas lus zoo, tab sis nws yuav tsum tau ntsuas qhov kev hloov pauv kub thiab tsis tuaj yeem ntsuas qhov kub hloov tam sim no. Muaj cov tshuab thermal feem ntau siv PT100, PT10, CU50, CU100. Qhov ntsuas kub ntsuas ntsuas ntawm platinum thermal thermal feem ntau {{}}}} Degree, thiab ntawm tooj liab Degree, thiab ntawm tooj liab Degree, thiab ntawm tooj liab Degree, thiab ntawm tooj liab Degree, thiab ntawm tooj liab Degree, thiab ntawm tooj liab Degree, thiab ntawm tooj liab Degree, thiab cov neeg tooj liab qib, thiab cov ntawv tooj liab tau rho tawm 40 txog 140 degree. Thermal deistors yog cais rau tib hom thermoounles, tab sis lawv tsis tas yuav tsum them nyiaj thiab pheej yig dua li thermocouples. Dab tsi yog qhov sib txawv ntawm cov lag luam platinum-tooj ​​liab thermal ua hauj thiab armored thermal resistors?

Tus tooj liab hluav taws xob tiv thaiv ntawm Industrial Cruction yog qhov ntsuas uas ntsuas kub ntawm cov hlau hloov thaum ntsuas kub. Tooj liab thermal resistors tau muab faib ua ke hom (tshem tawm) thiab hom platinum resistor) raws li cov qauv ntawm lawv cov leeg tiv thaiv. Thermal tsim tau yog tsim thiab tsim tau raws li cov txheej txheem tseem ceeb uas cov nqi tiv thaiv ntawm platinum hlau hloov nrog ntsuas kub. Raws li cov nqi tiv thaiv R (Degree) ntawm 0 degree, thiab 100 ohms (PT10)

Los ntawm cov ntsiab cai kub ntawm cov thermal resistors, nws tuaj yeem pom tau tias qhov kev hloov ntawm ntsuas kub ntsuas tau ntsuas los ntawm kev hloov ntawm lub thermal resistor. Yog li ntawd, kev hloov pauv ntawm ntau cov hlau tsis kam xws li cov hlau txhuas ntawm lub raj kav hlau ua yuav cuam tshuam rau kev ntsuas kub.

Lub tsho tiv thaiv thermal no yog lub cev muaj zog ntawm qhov ntsuas kub (resistor lub cev), ua hlau ua hlau, thiab hlau stainless. Nws sab hauv txoj hlua yog feem ntau φ {{0}}}}}} φ φ0.25mm. Piv nrog dog dig thermal resistors, nws muaj cov txiaj ntsig zoo hauv qab no:

Is loj me me, tsis muaj cua sib txawv sab hauv, thermal inertia, ntsuas me me;

② Cov khoom siv zoo, kev co ua kom tsis txhob, kev cuam tshuam kuj;

Pent Bent Bent, Yooj Yim rau Nruab;

④ Kev Pab Cuam Sijhawm ntev.

Armored Thermal resistor yog ib qho kev siv ntsuas kub feem ntau siv hauv cov twj paj nruag ntsuas. Thaum ob qho xaus ntawm ob qho kev sib tw sib txawv tau txuas rau hauv lub voj, thaum lub qhov kub ntawm ob lub junctions yog txawv, ib lub thermal tam sim no yuav tsim tawm hauv lub voj. Yog tias muaj qhov sib txawv kub ntawm qhov ua haujlwm kawg thiab qhov kawg ntawm thermocouple, cov zaub digital yuav qhia tau cov nqi kub sib xws los ntawm thermocouple.

Armored Thermal resistor yog ib qho kub sensor. Nws muaj ib qho uas cov taub me dua li cov rooj sib sau ua ke thermocouple, thiab haum rau kev teeb tsa hauv qhov chaw uas tsis tuaj yeem ntsia. Cov cuab yeej ua thermocoed tsim los ntawm lub tuam txhab siv cov thermal resistor ntsuas kub ntsuas cov ntsiab lus. Yog li ntawd, nws yog qhov tseeb, rhiab, muaj lub sijhawm ua kom nrawm nrawm, ruaj khov lub neej zoo, thiab lub neej kev pabcuam ntev.
