Cov ntaub ntawv pov thawj thiab cov hau kev rau Platinum Rhodium throdoco thermoco thermoco thermocoure:
Tus lej, qhov loj me, thiab saum npoo ntawm thermocouples yuav tsum tau txheeb xyuas nrog cov kab xev hlau yuav tsum tau ntsuas, thiab pom kev pom tseeb los ua kom tau raws li cov cai.
Newly txhim kho thermocouples uas tau dhau txoj kev ntsuam xyuas saum npoo yuav tsum tau qhia txog qhov kub tshaj plaws rau 2 teev ua ntej ntsuas ntshav siab, thiab tom qab ntawd txias rau hauv qhov cub rau qis dua 250 degree. Thermocouples hauv kev siv yuav tsum tsis txhob muaj kev qhia.
Qhov ntsuas kub rau kev txheeb xyuas qhov tseeb ntawm thermocouples yog txiav txim siab los ntawm cov tuab ntawm cov xaim hluav taws xob thiab hluav taws xob lub cheeb, raws li qhia hauv Table 3.
Kev ntsuas hluav taws xob ntawm cov ntsiab lus hauv qab 3 {{0 0 degree hloov pauv hauv cov roj da dej thaum ntsuas hluav taws xob tsis dhau ± 0.1 Qib.
Npog ob electrodes ntawm thermocouple nrog siab aluminium insulated ceramic tshij, thiab xov ntsuab nyob rau hauv tus Tsov tus tw kawg los txuas nrog cov ntaub ntawv terminal txhuas.
Cov hlau thermocouple yuav tsum tau ua los ntawm tib cov khoom siv raws li lub tooj hlau tooj liab nres qhov txuas. Qhov tsis kam ntawm lub tooj liab hlau ntawm 2 {{{}} degree yuav tsum tsawg dua 0.01724 μ ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω ω a.
Tso lub khob saib xyuas ntawm kev ntsuas ntsuas qhov ntsuas ntawm lub thermocouple, rub nws tawm ntawm cov roj tas li yog tsis pub tsawg tshaj 300 hli. Npog lub khob raj raj qhov ncauj ib ncig ntawm lub thermocouple nrog degreeh paj rwb.
Pull the reference end of the thermocouple out of the glass or plastic tube containing transformer oil or alcohol, and then evacuate and pull it out of the freezing point thermostat. Lub qhov tob yuav tsum tsis txhob tsawg dua 150 hli.
Qhov saum toj no yog cov khoom ntsuas hluav taws xob thiab cov hau kev rau platinum rhodium thermocolo thermocouples. Peb cia siab tias txhua tus neeg tuaj yeem nkag siab.
