Hauv kev ntsuas kub ntawm kev lag luam, lub caij nplooj ntoos hlav-loaded thermocouples thiab txav tau flange-mounted junction box type platinum resistance thermometers yog ob hom kub sensors. Lawv nthuav tawm qhov sib txawv tseem ceeb hauv kev tsim qauv, cov qauv kev ua haujlwm, cov yam ntxwv ntawm kev ua tau zoo, thiab kev siv cov xwm txheej. Cov hauv qab no muab kev sib piv los ntawm ntau qhov ntev los qhia meej lawv qhov sib txawv tseem ceeb.
I. Qhov txawv ntawm cov qauv tsim thiab kev teeb tsa
1. Caij nplooj ntoos hlav-Loaded Thermocouple
Lub ntsiab feature ntawm lub caij nplooj ntoos hlav-loaded thermocouple yog nws lub caij nplooj ntoos hlav-loaded kho qauv. Nws feem ntau yog siv lub caij nplooj ntoos hlav clip kom nruj rau qhov chaw ntawm cov khoom raug ntsuas, ua tiav kev teeb tsa nrawm los ntawm lub zog elastic ntawm lub caij nplooj ntoos hlav. Qhov kev tsim no tso cai rau kev sojntsuam kom hloov kho qhov ntsuas qhov kub thiab txias, haum rau cov xwm txheej uas yuav tsum tau hloov tsis tu ncua lossis zam kev teeb tsa threaded. Piv txwv li, nyob rau hauv lub chaw soj nstuam los yog cov khoom siv me me, lub caij nplooj ntoos hlav -loaded tsim ua kom muaj kev sib raug zoo ntawm kev sojntsuam thiab cov khoom siv saum npoo, txo cov thermal kuj thiab txhim kho kev ntsuas qhov tseeb.
Kev sojntsuam ib feem ntawm cov thermocouple yog nyob rau hauv ib lub raj tiv thaiv hlau (xws li stainless hlau), uas muaj cov ntsiab lus thermoelectric (xws li npib tsib xee-chromium-nickel- silicon alloy). Nws cov qauv tsim qhia txog qhov nruj ntawm lub caij nplooj ntoos hlav tiv tauj thiab cov lus teb ceev. Lub caij nplooj ntoos hlav tsim kom txo tau txoj kev tshav kub, txhim kho cov lus teb ceev, thiab txhim khu kev tiv thaiv rau cov neeg kho tshuab poob siab. Txawm li cas los xij, nws lub zog siv tshuab yog qhov tsis muaj zog, ua rau nws yooj yim rau xoob lossis puas tsuaj hauv vibrating lossis cuam tshuam ib puag ncig. Nws cov sealing kev ua tau zoo kuj yog qhov tsis zoo, thiab nws yuav tsis tiv taus kev kub ntxhov lossis cov xov xwm corrosive heev.
2. Movable Flange-Mounted Junction Box Hom Platinum Resistance Thermometer
Cov yam ntxwv tseem ceeb ntawm lub flange txav tau -mounted junction box hom platinum kuj tus pas ntsuas kub yog nws txoj kev sib txuas ntawm flange thiab cais lub thawv sib txuas. Nws feem ntau siv flange thiab ntsia liaj qhov rooj kho txoj kev, txuas cov kev sojntsuam mus rau cov khoom siv los ntawm kev sib koom ua ke ntawm flange, thaum lub thawv sib txuas yog tus kheej ntsia sab nraum cov khoom siv thiab txuas nrog kev sojntsuam ntawm cov xov hlau. Qhov kev tsim no tso cai rau kev sojntsuam kom hloov kho qhov tob tob, thiab lub thawv sib txuas yog nyob rau hauv thaj chaw nyab xeeb, ua kom yooj yim rau kev sib kis thiab kev saib xyuas. Piv txwv li, nyob rau hauv cov xwm txheej uas yuav tsum tau hloov kho ntawm qhov ntsuas qhov kub thiab txias tsis tu ncua los yog zam lub thawv hlws ris raug cuam tshuam los ntawm ib puag ncig, qhov kev sib cais no muab kev yooj yim dua thiab kev nyab xeeb.
Kev sojntsuam ib feem ntawm lub platinum tiv thaiv tus pas ntsuas kub yog nyob rau hauv ib lub raj tiv thaiv hlau, uas muaj cov platinum tsis kam (xws li Pt100). Lub thawv hlws ris feem ntau yog nyob sab nraum cov khoom siv thiab txuas nrog rau kev sojntsuam ntawm cov xov hlau. Nws cov qauv tsim qhia txog qhov yooj yim ntawm flange kev sib txuas thiab kev ywj pheej ntawm lub thawv sib txuas. Kev tsim flange txav tau tso cai rau kev nplua - kho qhov kev sojntsuam tom qab kev teeb tsa kom haum rau kev ntsuas sib txawv. Txawm li cas los xij, nws lub zog siv tshuab yog qhov tsis muaj zog, ua rau nws yooj yim rau xoob lossis puas tsuaj hauv vibrating lossis cuam tshuam ib puag ncig. Nws cov sealing kev ua tau zoo kuj yog qhov tsis zoo, thiab nws yuav tsis tiv taus kev kub ntxhov lossis cov xov xwm corrosive heev.
II. Qhov txawv ntawm Cov Cai Ua Haujlwm
1. Txoj Cai Ua Haujlwm ntawm Caij Nplooj Hlav -Loaded Thermocouple
Lub thermocouple yog raws li cov nyhuv Seebeck, qhov twg ob qhov sib txawv hlau conductors tsim kom muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias. Thaum ob lub hlau conductors txuas nrog rau tsim ib lub voj voog kaw, thiab ob qhov kev sib txuas muaj qhov sib txawv ntawm qhov kub thiab txias, ib qho hluav taws xob hluav taws xob tsim tawm hauv Circuit Court. Nws qhov loj me yog cuam tshuam nrog cov khoom siv thiab qhov kub ntawm qhov sib txawv ntawm cov junctions. Los ntawm kev ntsuas lub zog electromotive, qhov ntsuas kub tuaj yeem suav tsis ncaj. Thermocouples muaj siab rhiab heev; 1℃qhov kub thiab txias hloov ua rau muaj peev xwm hloov pauv ntawm kwv yees li 5-40 microvolts. Nws cov qauv yog qhov yooj yim, tsis muaj qhov txav txav, ua rau nws haum rau siab - kub, siab-siab, thiab corrosive ib puag ncig.
2. Txoj Cai Ua Haujlwm ntawm Movable Flange Mounted Junction Box Hom Platinum Resistance Thermometer
Lub platinum tiv thaiv tus pas ntsuas kub yog ua raws li cov yam ntxwv uas cov hlau tsis kam hloov nrog qhov kub thiab txias. Nws tus nqi tsis kam muaj qhov tsis yog-txoj kev sib raug zoo nrog kub thiab yuav tsum tau txiav txim siab los ntawm kev sab laj lub rooj lossis siv cov qauv (xws li R=R₀[1+At+Bt²+C(t-100)³]). Platinum kuj thermometers muaj siab rhiab heev; Kev hloov pauv kub ntawm 1℃ua rau muaj kev hloov pauv tseem ceeb hauv cov nqi tiv thaiv (piv txwv li, Pt100 muaj qhov tsis kam ntawm 100Ω ntawm 0 degree, thiab tus nqi kuj nce linearly nrog nce kub). Nws cov qauv yog qhov yooj yim, tsis muaj qhov txav mus los, ua rau nws haum rau kev ntsuas qhov nruab nrab thiab qis qis (-200℃txog 600 degree), tab sis muaj zog sib nqus teb los yog cov neeg kho tshuab vibrations yuav tsum tau zam kom tsis txhob cuam tshuam kev ntsuas qhov tseeb.
