Kev tsom xam ntawm qhov sib txawv ntawm thermocoples thiab RTDs

Thermocouples yog ua los ntawm ob qho kev sib cais uas tau koom nrog qhov kub thiab txias (}) kev sib tw (feem ntau txias txias) muaj nyob ntawm kev sib tshuam txias, lub sij hawm kub ntawm kev sib tw txias los ntawm kev sib txawv ntawm kev sib txawv ntawm kev sib tw txias, yog li ua kom muaj qhov tseeb kub ntawm kub kub {4 {4 4}} Qhov no yog hu ua kev npaj txias .

Tsis zoo li thermocouples, RTDs (Resistance kub cov khoom siv thiab cov xov hlau los ntawm cov hlau lossis cov hlau ua kom tsis kam lees thiab yuav ntxiv qhov yuam kev rau lub kev taw qhia .}} yog cov hlau txhuas tau ntev txaus, qhov yuam kev yuav raug kho kom loj thiab yuav tsum raug kho.

Kev lag luam siv {{}} xaim rTDs {}} ob lub xov hlau muaj cov hmoov txhuas los ntawm tus tswj hwm, lawv muab cov kev tiv thaiv tsuas yog ob qho Ua rau . Qhov ntsuas no yog tom qab ntawd rho tawm ntawm ob qho kev tiv thaiv tsis kam nyeem qhov kub ntawm lub resistor {}.

Daim ntawv thov sib txawv:

Ua raws li cov hom thermocouple siv nyob rau hauv lawv cov khoom lag luam (thermocuser muaj qhov dav dav, thiab retably} rattds muaj kub ntau ntawm {}} rau 1202 degrees Fahrenheit . vim muaj qhov kub tsawg dua, muaj qhov ruaj khov dua li lub sijhawm, thiab yooj yim dua rau calibrate .
