Puas yog PT100 ib thermocouple lossis ib tug thermal resistor? Yog cu50 ib tug thermocouple lossis ib tug thermal resistor? Dab tsi yog qhov sib txawv ntawm txhua lwm?

Puas yog PT100 ib thermocouple lossis ib tug thermal resistor? Yog cu50 ib tug thermocouple lossis ib tug thermal resistor? Dab tsi yog qhov sib txawv ntawm txhua lwm?

PT1 {0 0: PT txhais tau tias platinum tsis kam, tom kawg 100 txhais tau tias nws muaj 100 ohms ntawm 0 degree.

PT100 tsis yog thermocouple, ib chav kawm loj yog ib thermal resistor

CU50 tsis yog thermocouple, ib chav kawm loj yog ib thermal resistor

Cov lus ib txwm yog PT100 thermal kuj, Cu50 thermal kuj

Thermocouples thiab thermal instorsors yog hu rau ntsuas kub ntawm cov khoom, txawm hais tias lawv cov ntsiab lus thiab cov yam ntxwv tsis yog tib yam.

Ua ntej, qhia cov thermocouple {}} cov ntsiab lus siv kub tshaj plaws hauv {}} kev ntsuas kub thiab txias Thermocoidles yog raws li lub thermoelectric effect {} Tus lej sib txawv, tseem hu ua ob lub zog sib txawv, tseem hu ua cov nyhuv pom kev, tseem hu ua cov nyhuv pom? muaj peev xwm tsim nyob rau hauv lub voj kaw muaj ntawm ob lub peev xwm: Qhov kub ntawm qhov sib txawv ntawm ob qho kev sib txawv, yog li cov npe tau sib txawv, yog hais txog kev sib cuag ntawm ob qho sib txawv {{11 . Vim yog lawv cov khoom sib txawv ntawm cov khoom siv hluav taws xob,

Tam sim no, cov thoob ntiaj teb muaj cov qauv kev qhia tshwj xeeb {{} Ntsuas Celster, uas yog B, R, S, R, R yog rau Platinum Series ntawm thermocouples {{4 4}} vim platinum yog feem ntau yog cov khoom siv hlau hluav taws xob, ib txwm muaj cov hluav taws xob yooj yim, insulating cov hlab, cov tes tsho, tiv thaiv thiab Lub thawv hlws ris, thaum muaj cuab yeej thermocoed los ntawm kev sib xyaw ua ke xaim hluav taws xob {}} ncu rau cov khoom siv thermocouple { Cov xov hlau . Lawv txoj haujlwm tseem ceeb yog muab faib ua ob hom: Kev siv tshuaj ntxiv los ntawm kev siv hlau txuas ntxiv yog tib yam li cov nyiaj them tuaj Thermocouple {{}} Txawm li cas los xij, qhov txuas ntxiv ntawm cov xov hluav taws xob nrog cov khoom siv hluav taws xob nrog rau cov thermocouple yog txuas nrog liab kab ntawm cov xaim hluav taws xob, thiab cov khoom tsis zoo electrode txuas nrog cov khoom lag luam uas tseem tshuav rau cov xov tooj liab-tsib xee.

Thib ob, peb qhia cov thermal tiv thaiv. Cov cim ntsuas kub ntawm lub qhov kub thiab txias}}} nws muaj ntau yam zoo, thiab nws kuj tseem tuaj yeem ua tau Xa cov hluav taws xob hluav taws xob remotely. Nws muaj kev ntsuas kub thiab txias, tab sis nws yuav tsum tau ntsuas kub ntawm platinum thermal yog feem ntau200-800 degrees Celsius, tooj liab ua hauj lwm yog rho 40 mus rau 140 degrees Celsient, tab sis nws tsis tas yuav muaj cov xaim nqi thiab pheej yig dua li qhov kub kub {}}
