Calibration Principple & Practical Cycle Reference for Industrial Pin-Type Thermocouple
Calibration ua haujlwm tseem ceeb txuas los lav qhov kev ntsuas ntev ntev ntawm tus pin-hom thermocouple. Txawm tias cov khoom lag luam tshiab tawm hauv lub Hoobkas tuav lub sijhawm siv tau-qhov tseeb. Raws li qhov chaw tiag tiag thermal-kev ntxhov siab, tshuaj lom neeg-kev sib kis thiab kev ua haujlwm-kev poob siab, kev ntsuas kev ua tau zoo maj mam ploj mus. Ntau pawg tswj xyuas kev lag luam tsis muaj qhov tseeb calibration-cycle tus qauv, txawm tias ua cov calibration ntau dhau lawm thiab ua rau muaj kev ua haujlwm tsis tu ncua lossis tawm hauv cov sensors uncalibrated rau xyoo thiab pheej hmoo tsis pom kev ntsuas qhov sib txawv. Rational calibration-strategy ntsuas ntsuas-kev cia siab thiab kev saib xyuas-tus nqi.
Ob txoj hauv kev calibration tseem ceeb siv rau tus pin-hom thermocouple: kev sib piv-txoj kev calibration thiab calibration taag-point. Teem-point calibration cia siab rau theem-hloov kub ntawm cov khoom ntshiab-cov khoom, xa cov qib siab tshaj plaws siv-qhov tseeb, uas yog tshwj xeeb rau kev ntsuas ntsuas ntsuas-tus qauv-sensor. Kev sib piv-txoj kev calibration muab tso rau kev sim tus pin-hom thermocouple ua ke nrog traceable reference-standard tus pas ntsuas kub nyob rau hauv ruaj khov-kub calibration rauv. Kev nyeem ntawm ob lub sensors tau muab piv rau hauv ntau qhov kub thiab txias, tau txais cov ntaub ntawv sib txawv ntawm cov ntsuas ntsuas. Kev sib piv-txoj kev haum rau ntawm qhov chaw tshawb xyuas lub sijhawm thiab lub Hoobkas ua haujlwm batch-calibration.
Calibration-point xaiv yuav tsum npog qhov ua hauj lwm-kub qhov ntau ntawm lub hom phiaj sensor. Tsuas yog calibrating ib qho nruab nrab-kub-point tsis tuaj yeem cuam tshuam kev sib txawv ntawm kev ua haujlwm raws li kev ua haujlwm puv ntoob. Feem ntau peb-rau-tsib kub-cov ntsiab lus kis thoob plaws lub sijhawm ua haujlwm tau raug xaiv rau kev sib piv.
Kev txiav txim siab ntawm lub voj voog calibration yuav tsum ua tib zoo xav txog kev ua haujlwm kub, nruab nrab corrosiveness, thermal-cycling zaus thiab qhov tseeb-yuav tsum tau qib. Cov sensors xa mus rau qhov qis-kub me me-qhov xwm txheej tsis tseem ceeb-txheej txheem tuaj yeem siv sijhawm ntev calibration. Rau qhov kub-kub tseem ceeb-tsim-ua haujlwm ntsuas cov ntsiab lus nrog qhov yuav tsum tau ua kom raug nruj, lub voj voog calibration xav tau kom luv luv.
Kev siv-calibration-lub voj voog lub rooj rau tus pin-hom thermocouple nyob rau hauv qib sib txawv ua haujlwm-qhov xwm txheej:
表格
| Qib ua haujlwm | Hom ua haujlwm-kub | Txheej txheem-qhov tseeb | Pom zoo Calibration Cycle |
|---|---|---|---|
| Kev soj ntsuam me me uas tsis tseem ceeb | ＜400 degree | ± 3-5℃kam rau ua | 12-18 lub hlis |
| General-kev lag luam tseem ceeb-txheej txheem | 400-700 degree | ± 1-3℃kam rau ua | 6-12 lub hlis |
| High-temperature heavy-duty txheej txheem | ≥700 degree | ± 1-2℃nruj kam rau ua | 3-6 hli |
| Laboratory-precision-measurement hauj lwm | Full-range high-precuracy thov | Tsawg dua lossis sib npaug rau ± 1℃kam rau ua | 3-6 hli |
Kev kuaj pom qhov pom yuav tsum tau ua ua ntej calibration raug cai. Tshawb xyuas cov ntaub qhwv rau corrosion-qhov, tawg lossis deformation; tshuaj xyuas qhov them nyiaj-cable sab nraud-lub tsho tiv thaiv kev ncaj ncees thiab qhov kev sib txuas ntawm lub davhlau ya nyob twg. Kev puas tsuaj loj sensors yuav raug tshem tawm ncaj qha es tsis txhob nkim cov peev txheej calibration.
Nws tsim nyog tau txais kev ceeb toom tias calibration tsuas yog txheeb xyuas qhov kev ntsuas tam sim no. Yog tias qhov sib txawv dhau qhov kev tso cai, qhov rov ua dua tsis tuaj yeem rov ua haujlwm rau cov sensors raug kev txom nyem los yog kev sib kis sab hauv. Kev hloov pauv yuav tsim nyog rau xws li kev laus-kev puas tsuaj tus pin-hom thermocouple.
Scientific-calibration kev tswj ua ke ua ke ib ntus kev soj ntsuam kev sib piv-calibration thiab tsis tu ncua ntawm-site cross-check tiv thaiv reference-sensor. Custom-application scheme tuaj yeem tsim tshwj xeeb kev tshuaj xyuas-thiab-calibration workflow raws li cov txheej txheem kam rau ua thiab cov khoom siv ua haujlwm tiag tiag.
