Nyob rau hauv lub tshav pob ntawm kev ntsuas kub, raug cov thermocouples thiab movable threaded kev twb kev txuas lub thawv hom platinum kuj thermometers yog ob hom kub sensors. Lawv muaj qhov sib txawv tseem ceeb hauv kev tsim qauv, cov qauv kev ua haujlwm, cov yam ntxwv ntawm kev ua haujlwm, thiab cov xwm txheej ntawm daim ntawv thov. 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. Tshem tawm Thermocouple
Lub ntsiab feature ntawm qhov raug thermocouple yog tias nws ntsuas qhov kawg yog ncaj qha mus rau qhov ntsuas nruab nrab, tsis tas yuav tsum muaj kev tiv thaiv ntxiv. Nws feem ntau yog ua los ntawm ob lub xov hlau sib txawv (xws li npib tsib xee-chromium thiab npib tsib xee-silicon) welded ua ke los tsim qhov ntsuas kawg, uas yog ncaj qha tso rau hauv qhov ntsuas nruab nrab. Nws txoj kev tsim qauv qhia txog kev sib cuag ncaj qha thiab teb sai. Qhov tsim tawm ntawm qhov ntsuas qhov kawg tso cai rau nws nkag siab qhov hloov pauv ntawm qhov nruab nrab qhov kub thiab txias, ua rau lub sijhawm teb ceev heev, ua rau nws tsim nyog rau cov xwm txheej uas yuav tsum tau ntsuas qhov ntsuas kub tam sim. Piv txwv li, hauv kev ua zaub mov lossis kev lag luam tshuaj, cov khoom siv thermocouples tuaj yeem saib xyuas qhov kub thiab txias hloov hauv cov kua lossis roj, ua kom muaj kev nyab xeeb ntawm cov txheej txheem ntau lawm. Txawm li cas los xij, nws cov txheej txheem kev teeb tsa yuav tsum ua kom ntseeg tau tias qhov ntsuas qhov kawg yog tag nrho rau hauv qhov ntsuas nruab nrab, uas ua rau kom qhov nyuaj ntawm kev teeb tsa. Tsis tas li ntawd, cov hlau hlau yuav oxidize los yog corrode nyob rau hauv siab - kub los yog corrosive ib puag ncig, cuam tshuam rau ntev - lub sij hawm stability.
2. Movable Threaded Connection Box Hom Platinum Resistance Thermometer
Lub ntsiab feature ntawm lub movable threaded kev twb kev txuas lub thawv hom platinum kuj tus pas ntsuas kub yog nws txav threaded kev twb kev txuas thiab platinum hlau winding qauv. Nws feem ntau yog siv cov xov uas txav tau (xws li M18 × 1.5) kom ua tiav kev teeb tsa ruaj ntseg los ntawm kev ntsuas nws mus rau saum npoo ntawm cov khoom ntsuas. Sab hauv, platinum hlau yog qhov txhab ntawm lub ceramic los yog mica thav duab los ua qhov kub thiab txias -sensing caij, uas yog ces txuas mus rau sab nraud Circuit Court los ntawm lub thawv txuas. Kev sib txuas lub thawv tsim ua kom yooj yim rau kev xa cov teeb liab thiab kev saib xyuas, thaum tseem muab kev tiv thaiv tsis muaj dej thiab plua plav. Piv txwv li, nyob rau hauv cov khoom noj khoom haus los yog kev lag luam industries, lub movable threaded tsim kom muaj kev sib raug zoo ntawm cov sojntsuam thiab cov khoom nto, txo tshav kub thaum lub sij hawm tshav kub conduction txheej txheem. Nws cov qauv tsim qhia qhov yooj yim ntawm kev sib txuas ntawm threaded thiab stability ntawm platinum hlau. Cov qauv tsim txav tau txo qis qhov cuam tshuam ntawm ib puag ncig ntawm kev ntsuas qhov tseeb thiab txhim khu kev tiv thaiv rau cov neeg kho tshuab kev co thiab kev poob siab. Txawm li cas los xij, nws cov txheej txheem kev teeb tsa yuav tsum tau ua kom ntseeg tau tias cov xov muaj kev sib cuag nrog lub ntsej muag ntawm cov khoom raug ntsuas, uas ua rau muaj qhov nyuaj ntawm kev teeb tsa. Tsis tas li ntawd, lub thawv sib txuas yuav raug txo qis kev ua tau zoo thaum lub sij hawm vim yog ib puag ncig.
II. Qhov txawv ntawm Cov Cai Ua Haujlwm
1. Txoj Cai Ua Haujlwm ntawm Kev Tiv Thaiv Thermocouple
Thermocouples yog raws li cov nyhuv Seebeck, qhov twg ob lub hlau conductors sib txawv ua 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. Qhov loj ntawm lub zog no muaj feem xyuam rau cov khoom siv thiab qhov kub thiab txias 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. Lawv cov qauv yog qhov yooj yim, tsis muaj qhov txav txav, ua rau lawv haum rau siab -kub, siab-siab, thiab corrosive ib puag ncig. Cov qauv tsim tawm tso cai rau cov lus teb nrawm dua, tab sis kev saib xyuas yuav tsum tau them rau oxidation thiab corrosion ntawm cov hlau hlau.
2. Txoj Cai Ua Haujlwm ntawm Movable Threaded Mounting Junction Box Hom Platinum Resistance Thermometer
Platinum resistance thermometers yog raws li cov yam ntxwv uas cov hlau tsis kam hloov nrog qhov kub thiab txias. Lawv cov nqi tsis kam muaj qhov tsis zoo -txoj kev sib raug zoo nrog kub thiab yuav tsum tau suav nrog cov ntxhuav lossis cov qauv (piv txwv li, Pt100 muaj qhov tsis kam ntawm 100Ω ntawm 0 degree, thiab tus nqi kuj nce linearly nrog nce kub) los txiav txim qhov ntsuas kub. Platinum kuj thermometers muaj siab rhiab heev; 1℃qhov kub thiab txias hloov ua rau muaj kev hloov pauv tseem ceeb hauv cov nqi tiv thaiv. Lawv cov qauv yog qhov yooj yim, tsis muaj qhov txav txav, ua rau lawv haum rau kev ntsuas qhov tseeb hauv nruab nrab thiab qis kub (-200℃txog 600 degree), tab sis muaj zog sib nqus teb los yog cov neeg kho tshuab kev co yuav tsum zam kom tsis txhob cuam tshuam qhov ntsuas qhov tseeb. Cov qauv tsim qauv txav tau tso cai rau kev ntsuas kev ua haujlwm ruaj khov txawm tias nyob hauv qhov chaw kub kub.
