Ua haujlwm ua haujlwm ntawm kub sensor

1.}} txoj ntsiab cai ntawm kev siv ntawm kub sensor thermocouple

Kub Sensor Thermocouple yog ib qho kev siv ntsuas kub feem ntau tau tshawb nrhiav hauv kev lag luam {}} nws zoo yog:

① Kev ntsuas siab yog qhov tseeb.}} Vim tias qhov ntsuas kub tau ntsuas, nws tsis cuam tshuam los ntawm cov khoom nruab nrab {}}

② Kev ntsuas kev ntsuas kub .}}}}}} +2800℃(xws li tungsten-rhenium) .

Cov qauv yooj yim thiab siv tau yooj yim {. cov xov hlau thuv, thiab tsis muaj qhov sib txawv ntawm ob lub tes tsho sib txawv, thiab yog qhov yooj yim heev rau siv .

1. Cov txheej txheem kub ntawm kub sensor thermocouple kub ntsuas

Weld ob tug neeg coj thiab semiconductors a thiab b ntawm cov ntsiab lus sib txawv ntawm ob qho, yog li ua ib qho kev sib txawv ntawm ob qho tib si txuas nrog lub voj voog thermocouples siv cov nyhuv no mus ua haujlwm .

{{02.} hom thiab qauv sib xyaw ntawm cov ntsuas kub kub sensor thermoco

(1) Hom ntsuas kub sensor thermoco

Cov ntsuas kub thiab txias rau cov qauv ntsuas kub thiab txias thiab txias rau cov qauv kub thiab txias. Kev Xaiv . Cov Khoom Kub No Tsis Zoo Li Cas Los Ntawm Lub Ib Hlis 1, 1988, kuv muaj qhov sib txawv ntawm lub Ib Hlis 1, thiab qee qhov kub thiab txias. IC cov qauv, thiab xya hom kev hloov kho cov qauv kub sensor thermocouples si sensor kub thermocouples nyob rau hauv kuv lub teb chaws.

(2) cov qauv ntawm cov ntsuas kub kub sensor thermocouple

Txhawm rau kom ntseeg tau tias qhov ntsuas kub ntsuas hluav taws xob thermocouple ua hauj lwm dawb paug thiab stably, nws cov qauv yuav tsum muaj raws li nram no:

① vuam ntawm ob thermocouples uas yog qhov ntsuas kub ntsuas hluav taws xob thermocouple yuav tsum yog khov kho;

Yog ob thermocouples yuav tsum muaj insulated zoo los ntawm ib leeg los tiv thaiv cov tsheb luv luv;

Kev sib txuas ntawm cov xaim xaim ntxiv thiab qhov kawg ntawm qhov ntsuas kub ntawm qhov ntsuas kub thermocouple yuav tsum yooj yim thiab ntseeg tau;

④ Tes Tsho Tiv Thaiv yuav tsum muaj peev xwm ua kom ntseeg tau tias qhov thermocouple yog tag nrho los ntawm kev phom sij .

{{03. kub ntawm kev them nyiaj ntawm qhov txias txias ntawm qhov kub sensor thermocouple

Vim tias cov ntaub ntawv ntawm qhov ntsuas kub ntawm qhov ntsuas kub yog feem ntau yog siv cov khoom siv ntsuas kub thiab txo qhov ntsuas kub thiab txias rau cov ntsuas kub terminal{{0}} It must be pointed out that the role of the temperature sensor thermocouple compensation wire is only to extend the hot electrode, so that the cold end of the temperature sensor thermocouple moves to the instrument terminal in the control room. It itself cannot eliminate the influence of the cold end temperature change on the temperature measurement, and it does not play a compensatory lub chroole . Yog li no, lwm yam kev hloov kho kev hloov kho yuav tsum tau them rau qhov cuam tshuam ntawm qhov txias txias kub ≠} .

Thaum siv cov ntsuas kub ntsuas hluav taws xob thermocouple them, thiab ntsuas kub tsis tuaj yeem txuas nrog cov hlau uas yuav tsis tshaj 100 degree.

{{0 {}} Lub hauv paus ntsiab lus ntawm kev siv ntsuas kub sensor thermal

Kub sensor thermal ua hauj lwm yog feem ntau siv cov detectors yog qhov ntsuas kub siab tshaj plaws hauv lawv, tab sis kuj tau ua rau cov qauv ntsuas kub {}}

1. Lub hauv paus ntsiab lus thiab cov ntaub ntawv ntawm cov ntsuas kub scermal thermal ntsuas kub ntsuas kub

Kub sensor thermal kub ua ntsuas yog raws li cov khoom siv ntshiab ntawm cov neeg hlau, thiab cov neeg siv npib uas tam sim no, Manganese thiab rhodium tau pib siv rau ua kom kub sensor tawm tsam {{} Piv txwv, Omega's PT100 Sensor suav nrog qhov kev sim kub {}}

2. cov qauv ntawm kub sensor thermal resistor

(1) los ntawm hom-hom kub sensor thermal thermal lub hauv paus kev ntsuas kub yog ntsuas qhov ntsuas kub ntawm qhov ntsuas kub yog li ntawd, kev hloov pauv ntawm ntau cov txhuas xaim ntawm qhov kub sensor resistor yuav cuam tshuam rau qhov ntsuas kub ntawm cov hmoov txhuas kev ntsuas lossis plaub-xaim hluav taws xob feem ntau tau saws .

(2) Armored Kub Sensor Thermal Resist Qhov Ntsuas Kub (Resistion Cov Khaub Ncaws Kub (Resulating Cov Khoom Siv Hluav Taws Xob

Piv nrog cov ntsuas kub uas yog ntsuas hluav taws xob thermal, nws muaj qhov loj me me: ① me me, tsis muaj huab cua sib txawv, thermal inertia, kev ntsuas me me; ② Qhov kev ua tau zoo heev, kev co ua kom tau, thiab poob siab tsis kam; ③ Yuav bent, yooj yim rau nruab ib lub neej ntev .

(3) Qhov kawg sensor thermal resistor Qhov kawg ntsuas kub siab, nws tuaj yeem tsim nyog rau ntsuas qhov kawg ntawm cov kabmob thiab lwm qhov.

(4) Kub FlasPoof Kub Sensor resistor Lub thawv hlaus sov thermal siv cov kab ke sib xyaw ua ke ntawm cov tshuab ntau lawm, thiab cua sov} rau kev ntsuas kub hauv kev tawg-cov chaw muaj kev phom sij hauv Bla ~ B3C theem ntau {}}

3.} muaj pes tsawg leeg ntawm kub sensor thermal ntsuas ntsuas kub

Qhov ntsuas kub sensor thermal kub resistor kub ntsuas ntsuas feem ntau muaj ntsuas kub distor, txuas cov xov hlau thiab cov ntsuas xov tooj cua thiab saib cov ntsiab lus hauv qab no:

② Lub thermal tsis kam ntawm cov ntsuas kub yog yuav tsum muaj raws li tus naj npawb kawm tiav ntawm cov khoom siv ntsuas

② Txhawm rau tshem tawm cov cawv ntawm kev hloov pauv ntawm cov hlau sib txuas, peb-kev sib txuas hlau yuav tsum tau saws .
