Qhov sib txawv ntawm thermal resistor thiab thermocouple

Thermal intorses yog feem ntau siv cov detectors nyob rau hauv nruab nrab thiab tsis ruaj khov rau kev ntsuas kub, tab sis kuj tau ua rau cov qauv ntsuas kub {}}

Tsis zoo li cov ntsiab cai ntsuas kub ntawm thermoces resistors kub thiab txias}} Yog li ntawd, muaj ob hom hlau thermal resistors thiab semiconductor bermistors. Cov neeg tiv taus cov khoom lag luam hlau feem ntau, yog, rt}} (t0 .

Hauv cov qauv, RT yog cov tsis kam nqi ntawm qhov kub t; Rt {{{{{0}}}} yog cov tshuaj tiv thaiv tus nqi tiv thaiv ntawm T0 (feem ntau yog0=0 degree); Puas yog cov ntsuas kub sovefficieci. Cov kev sib raug zoo ntawm tus nqi tiv taus thiab kub ntawm semiconductor tus mob kub yog rt {{} AB / t

Hauv cov qauv, RT yog cov tsis kam nqi ntawm qhov kub t; A thiab B yog nyob ntawm tus qauv ntawm cov khoom siv semiconductor {}}}} {{}}} Lawv tau siv dav hauv Kev ntsuas kub thiab txias thiab tswj cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob kom haum rau cov kev ntsuas kom yog qhov ntsuas kub}}} Lawv tau siv dav hauv cov txheej txheem tswj {}}

Thermal Resistor Cov Khoom Siv Thermal Reversor yog feem ntau ua los ntawm cov neeg siv hluav taws xob tsis zoo tshaj plaws rau kev ua haujlwm tam sim no. Despors .

Hom thermal resistors

(1) Armored Thermal Desistors: Cov Cuab Yeej Thermal Thermal yog cov khoom siv hluav taws xob (ua rau muaj cov khoom siv hluav taws xob tsis zoo: Kev sib pauv huab cua sab hauv, kev ntsuas me me hauv thermal inertia; ② Cov khoom siv zoo, kev co ua kom tau, thiab kev tiv taus kev tawm tsam; Pent tuaj yeem khoov thiab yooj yim rau nruab; ④ Kev Pab Cuam Ntev Ntev .

(2) Precision Thermal resistor: Cov yam ntxwv ntawm cov thermal resistor {}}}}}} Yog li ntawd, kev hloov pauv ntawm cov kav hlau ua haujlwm xws li cov kav hlau ua haujlwm ntawm lub thermal resistor yuav cuam tshuam rau lub kev ntsuas kub ntsuas ntsuas . thiaj li yuav tshem cov hlau txhuas, peb-xaim hluav taws xob feem ntau siv .

(3) End lub ntsej muag thermal resistor: lub ntsej muag kawg thermal kub thermal kub thiab yog qhov ntsuas kom haum rau lub ntsej muag kub ntawm cov kabmob thiab lwm qhov.

(4) FlameProof Thermal Thermal Resistor: Kev tawg ntawm cov qauv hluav taws xob uas tawg tau yog siv rau cov chaw sib tw ntawm cov chaw tshwj xeeb hauv Bla ~ B3C theem cheeb tsam .

Feem ntau siv cov hlau thermal resistors hauv kev hloov pauv ntawm cov cuab yeej thermal no cov khoom siv yug dua tshiab, thiab cov nqi tiv thaiv yuav tsum muaj cov nqi nruab nrab muaj nuj nqi nrog kev hloov kub (tawm kev sib raug zoo).

Cov teeb liab kev sib txuas ntawm thermal resistor yog lub teeb tsa qhov ua kom tau hloov mus rau lub computer tswj kev hloov pauv hloov mus rau cov hlau ua hlau {}}

Tam sim no, cov khoom siv thermal feem ntau siv yog Platinum thiab oxidizing media thiab oxidizing tshaj tawm, thiab qhov siab dua qhov ntsuas kub, cov me dua cov nqi tiv thaiv tsis kam; Tooj liab cov neeg muaj nqi ntawm txoj kev sib raug zoo thiab qhov ntsuas kub, yog qhov yooj yim rau cov xov tooj uas tsis yog, thiab yooj yim rau hauv qhov kub thiab txias dua 150.

Kev lag luam thermal yog ntsia ntawm lub vev xaib tsim khoom, thiab muaj qee chav tswj hwm, yog li cov thawj coj ntawm cov ntsuas hluav taws xob yuav muaj kev ntsuas qhov ua rau ntsuas tau ntxiv rau qhov ntsuas tau {}}

Tam sim no, muaj peb txoj kev tseem ceeb los ua rau cov kab hlau ua kom muaj feem xyuam nrog cov hlau uas muaj feem cuam tshuam rau cov khoom siv thiab txoj kev sib txuas no tsuas yog tsim nyog rau qee zaus nrog kev ntsuas qis Kev Raug Mob .} ○ 2 Peb tus ua rau muaj kev cuam tshuam nrog tus choj ntawm kev siv tshuaj tiv thaiv kab mob {} 10}} ○ 3 Plaub-xaim hluav taws xob: Txuas ob lub xov tooj ntawm lub qhov hluav taws xob uas muaj peev xwm ua rau muaj ob qho kev ua haujlwm ntawm lub zog thib ob Nrhiav tau.

Lub thermal resepts ib peb-xaim txuas kev sib txuas yog feem ntau ntawm cov xaim hluav taws xob yog feem ntau ntawm cov xov tooj cua tsis sib xws) Kuj tsis kam lees qhov kev tawm tsam ntawm tus choj?

Hauv kev lag luam, peb-hlau txuas kev sib txuas yog feem ntau siv. cov teeb meem. muaj pes tsawg leeg ntawm cov cua sov resistor kub ntsuas

(1) Kev ntsuas cua sov uas ntsuas tau feem ntau muaj cov ntaub lag luam thermal, txuas cov xov hlau thiab cov khoom siv ntawm ob qho tib si hauv qab no yuav tsum tau sau tseg:
① Lub thermal resistor thiab cov twj tso tawm yuav tsum muaj tib tus lej kawm tiav
② Txhawm rau tshem tawm cov cawv ntawm kev hloov pauv ntawm txoj kev txuas nrog cov hlau sib txuas, thov mus rau cov tshooj 3 ntawm cov kab ntawv no {}}

(2) Armored Thermal Resistor Lub Tsho Tiv Thaiv Thermal yog feem ntau ua rau lub cev muaj zog, thiab qhov tsis txaus ntseeg tau 8m} Nws muaj cov hlau hluav taws xob, thiab cov hlau ua kom zoo nkauj nrog cov txiaj ntsig zoo tib yam:
Qhov loj me me, tsis muaj cua sib txawv sab hauv, kev ntsuas me me hauv cov thermal inertia;
② Cov khoom siv zoo, kev co ua kom tau, thiab kev tiv taus kev tawm tsam; ③ Yuav Bent kom yooj yim installation ④ service lub neej .

(3) Kawg lub ntsej muag thermal resistor xaus lub ntsej muag thermal kub lub ntsej muag thiab maj mam kho qhov ntsuas kub ntawm qhov kub thiab txias ntawm cov kabmob thiab lwm qhov.

(4) FlameProof thermal thermal resistors siv cov roj sib xyaw ua ke ntawm lub plhaub los yog ua rau muaj tus nqi pheej yig ib .} Yog siv vuam siv, nws yuav tsum ntsuas tom qab nws tuaj yeem siv {{4}

Qhov sib txawv ntawm thermocouples thiab thermal resesors
Ob qho kev ntsuas kub thiab cov thermal tiv thaiv kub ntawm ntsuas ntsuas ntsuas kub ntawm kev ntsuas qhov ntsuas kub ntawm qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas, txawm hais tias lawv cov yam ntxwv thiab cov yam ntxwv sib txawv yog txawv.

Ua ntej, cia peb qhia cov thermocouples {{0} qauv hluav taws xob ntau, thiab muaj peev xwm siv hluav taws xob dav dav, thiab kev ntsuas dav dav}}} Ntsuas cov cai thermouvles yog raws li lub thermoelectric effect {}} Qhov kev tshwm sim ntawm ob qho tib si sib txawv, tseem hu ua cov nyhuv ntawm cov nyhuv pom. tus Thermoelectric peev xwm tsim nyob rau hauv lub voj kaw muaj ob qho kev sib txawv los ntawm ob qho tib si muaj peev xwm sib txawv, yog li lub npe sib txawv tsim thaum ob tus neeg sib txawv muaj kev sib cuag vim tias lawv cov khoom siv hluav taws xob sib txawv yog tsim kom muaj kev sib txawv ntawm cov khoom siv hluav taws xob, uas cov stipulates uas thermocouples muab faib ua yim yam Kev faib tawm, uas yog B, R, S, K, n, E, J thiab Sucees} Nws muaj cov khoom siv platinum yog ib qho zoo tshaj plaws ntawm cov hlau, lawv kuj tau hu ua cov hlau zoo nkauj thermocouples, thiab cov seem uas yog hu ua pheej yig hlau thermoco thermocouples.

Muaj ob txoj kev teeb tsa ntawm cov thermouples, hom dog dig thiab ncab {{}} Txawm li cas los xij, hluav taws xob kev sib sau ua ke ntawm qhov laj kab hluav taws xob yuav tsum muaj hlau tshwj xeeb los xa, uas peb hu rau cov thermocouple {2} Qhov kawg ntawm lub zog sib txawv, yog li qhov ntsuas kub ntawm qhov kawg yog ruaj khov {}

Cov xov cov xov hlau tau muab faib ua cov hlau uas mob cermocouple yog qhov tib yam li lub tshuab hluav taws xob tsis sib xws li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob zoo ib yam li cov xaim hluav taws xob nrog cov hlau sib txuas ntawm cov xaim xaim thiab cov Thermocouple feem ntau heev meej {{3 tus ncej zoo ntawm cov khoom them nyiaj liab, thiab cov hlau tsis zoo yog ua los ntawm tooj liab-npib yog ua los ntawm tooj liab-tsib xee.

Thib ob, cia peb qhia cov thermal resistor . Qhov kev ntsuas kub uas muaj ntau yam khoom siv kub, xws li kev sib pauv hluav taws xob ntawm hluav taws xob Cov cim, siab ruaj khov, muaj zog ruaj khov, kev ntsuas kub, tab sis nws yuav tsum tau ntsuas qhov kub thiab txias} rho 40 txog 140 degrees Celsius {... 11}} Thermal tsim tau yog faib rau tib lub thermoounles thiab yog cov khoom siv nyiaj thermal ntau dua li thermal khub niam txiv.
