Yuav Ua Li Cas Tiv Thaiv Kev Ua Phem Hauv Hlau Tube Kev Tshawb Fawb Kev Ncua Kev Sib Nqus Box Hom Platinum Resistance Temperature Detectors

Hlau raj sojntsuam insertion junction box hom platinum kuj kub detectors yog dav siv nyob rau hauv industrial ntsuas kub, thiab lawv stability ncaj qha cuam tshuam rau qhov tseeb ntawm cov txheej txheem tswj. Txhawm rau tiv thaiv kev ua yuam kev zoo, ib qho kev tiv thaiv zoo yuav tsum tau tsim los ntawm plaub qhov loj: xaiv thiab sib txuam, kev teeb tsa tus qauv, kev tiv thaiv ib puag ncig, thiab kev saib xyuas raws sijhawm.

 

I. Kev Xaiv Kev Tshawb Fawb: Ua kom muaj kev sib txuam ntawm Sensor rau kev ua haujlwm

Txhais qhov kub thiab txias chav kawm:** Rau kev lag luam ambient kub (-20℃-500 degree), Pt100 platinum kuj kub detectors yog nyiam. Cov chav kawm raug yuav tsum raug xaiv raws li qhov xav tau: Chav A (± 0.15 degree) lossis Chav B (± 0.3 degree). Rau qhov kub kub ntau tshaj 500 degree, thermocouples yuav tsum tau siv hloov.

Match Protective Tube Khoom thiab Txoj Kev Sib Txuas: Hauv corrosive media, 316L stainless hlau lossis Hastelloy tubing yuav tsum raug xaiv. Txoj kev kho kom pom zoo yog WZP-231 hom tsau threaded hom (M27 × 2) + waterproof hlws ris lub thawv qauv kom ntseeg tau tias kev sib khi ruaj khov.

Match Protective Tube Khoom thiab Txoj Kev Sib Txuas: Hauv corrosive media, 316L stainless hlau lossis Hastelloy tubing yuav tsum raug xaiv.

Optimal Dual-Component Design: Kev teeb tsa ntawm ob lub platinum tiv thaiv tus pas ntsuas kub yog siv los ntsuas cov ntsiab lus tseem ceeb, ua kom yooj yim rau kev txheeb xyuas qhov tsis txaus ntseeg thiab kev sib piv online, thiab ua kom tshawb pom qhov yuam kev raws sijhawm.

 

II. Standard Installation: Tshem tawm tib neeg-Induced Damage and Connection Hazards

Xyuas kom txaus Insertion qhov tob: Qhov kev sojntsuam yuav tsum tau muab tso rau hauv qhov ntsuas nruab nrab mus rau qhov tob Ntau dua lossis sib npaug li 10 npaug ntawm txoj kab uas hla ntawm lub raj tiv thaiv (feem ntau Ntau dua lossis sib npaug li 100mm) kom tsis txhob ntsuas qhov sib txawv vim qhov kub tsis txaus.

Tswj Kev Nyuaj Siab: Tsis txhob yuam kom khoov lub raj hlau thaum lub sijhawm teeb tsa. Lub vojvoog dabtsi yog khoov yuav tsum siab dua lossis sib npaug li 50 hli kom tiv thaiv kev qaug zog ntawm cov hlau hauv platinum. Siv lub torque wrench kom ceev cov xov, tsis txhob muaj zog ntau dhau uas tuaj yeem tawg qhov sealing nto.

Corect Wiring to Prevent Interference: Siv shielded twisted -pair cable nrog ib tug ntoo khaub lig-sectional cheeb tsam Ntau tshaj los yog sib npaug rau 1.5mm². Cov terminals yuav tsum nruj nruj kom tiv thaiv kom tsis txhob muaj kev tiv thaiv ntau ntxiv. Cov txheej thaiv thaiv yuav tsum tau muab tso rau ntawm ib kawg thiab kom deb ntawm qhov chaw muaj zog electromagnetic xws li motors thiab zaus converters.

 

III. Environmental Control: Txo qhov kev pheej hmoo ntawm kev puas tsuaj sab nraud

Cov dej noo thiab dej tsis kam yog qhov tseem ceeb: Cov thawv sib txuas yuav tsum muaj IP65 lossis siab dua kev tiv thaiv. Sealing rings yuav tsum tau kuaj xyuas thiab hloov tsis tu ncua. Rau kev siv sab nraum zoov, yuav tsum tau nruab ib lub hau los nag los tiv thaiv kev ya raws uas tuaj yeem ua rau luv luv lossis oxidation.

Tiv Thaiv Electromagnetic Interference: Hauv cov chaw soj nstuam lossis siab -ib puag ncig cuam tshuam, qhov kev yuav khoom yuav tsum muaj opto- cais tawm ntawm cov channel thiab tuav qhov deb ntawm Ntau dua lossis sib npaug li 1m los ntawm cov khoom siv xws li centrifuges thiab spectrometers.

Tsis txhob overheating: Lub sijhawm ntev - lub sijhawm ua haujlwm kub yuav tsum tsis pub tshaj qhov ntsuas kub tsis kam ntawm cov khoom siv tiv thaiv thiab cov khoom thaiv (piv txwv li, PTFE insulated hlau Tsawg dua lossis sib npaug li 250 degree) los tiv thaiv cov khoom laus thiab tsis ua haujlwm.

 

IV. Kev tshuaj xyuas thiab tu tsis tu ncua: Kev ceeb toom ntxov ntawm kev ua txhaum

Lub rooj tshuaj ntsuam xyuas	Lub voj voog	Txoj kev thiab Standard
Kev ntsuas ntsuas	Txhua hli	Multimeter los xyuas seb qhov tsis kam ntawm Pt100 ntawm chav tsev kub ua tau raws li qhov nominal nkhaus.
Rwb thaiv tsev Resistance Test	Txhua 6 lub hlis	Megohmmeter (500V DC) los ntsuas qhov rwb thaiv tsev ntawm cov hlau lead thiab cov casing; Ntau dua los yog sib npaug rau 100MΩ yog ​​txais.
Kev tshuaj xyuas kab mob	Peb lub hlis twg	Qhib lub hlws ris lub thawv, tshem tawm cov plua plav thiab hlau shavings, thiab xyuas seb puas los yog oxidized terminals.
System Calibration	Txhua 6-12 lub hlis	Ua qhov system calibration siv tus qauv ntsuas kub tas li kom ntseeg tau tias qhov ntsuas tsis raug nyob rau hauv qhov kev txwv.

Tswv yim: Tsim ib qho khoom siv cav, sau txhua cov ntaub ntawv soj ntsuam, thiab txheeb xyuas cov cim kev puas tsuaj thaum ntxov los ntawm kev tsom xam.

 

V. Summary of Fault Prevention Key Points

Ua ntej siv lub ntsuas ntsuas tshiab, siv lub ntsuas ntsuas ntawm R × 1 ntau rau kev sim thawj zaug. Yog tias nws qhia "∞", lub Circuit Court qhib thiab nws yuav tsum tsis txhob siv.

Thaum lub sij hawm kaw, tu kom huv si txhua qhov seem (xws li tshuaj lom neeg, cov roj stains) los ntawm qhov chaw sojntsuam, so kom qhuav, thiab khaws cia kom tsis txhob xeb.

Cov cuab yeej yuav tsum raug xa mus rau kev tshuaj xyuas nruj me ntsis raws li lub voj voog metrological; cov cuab yeej uas tsis tau ntsuas los yog tau dhau hnub tas sij hawm yuav tsum tsis txhob muab tso rau hauv.

Lub hauv paus ntawm kev tiv thaiv yog nyob rau hauv "kev tshawb nrhiav thaum ntxov, ceev ceev, thiab kev tiv thaiv hnyav." Ntau qhov txhaum tsis muaj cov tsos mob pom tseeb hauv lawv cov theem pib; Tsuas yog los ntawm kev tshuaj xyuas cov txheej txheem peb tuaj yeem hloov pauv los ntawm kev saib xyuas rov qab mus rau kev saib xyuas zoo.
