Ua haujlwm ua haujlwm thiab cov yam ntxwv ntawm-thaj chaw zaub mov sib xyaw ua ke

Kev tawg nrawm-pov thawj kub thermistor Nta: Ob-xaim tawm 4-20 ma, muaj zog los tiv thaiv kev cuam tshuam; Txuag tus nqi ntawm cov xov tooj ntawm cov xov tooj thiab hloov chaw kub; Muaj kev nyab xeeb thiab txhim khu kev qha, nrog lub neej kev pabcuam ntev; Txias qhov xaus kev kub ntxhov tsis siv neeg, tsis kho kab kev kho Circuit Court;
Ua hauj lwm cov cai ntawm kev sib xyaw ua ke-ntawv pov thawj thermistor
Qhov hloov pauv hauv thermoelectric peev txheej (tsis kam) ntsuas thaum lub sijhawm ua haujlwm tau ua rau lub cim hluav taws xob tsis sib xws rau cov khoom siv ua haujlwm kom pom cov nqi kub.
Tawg cov ntawv pov thawj thermocouple (resistector) siv cov ntsiab cai ntawm kev sib kis kis tawg-pov thawj. Thaum qhov tawg nyob sab hauv lub chav, nws tuaj yeem tua thiab txias thiab txias los ntawm kev sib txawv, tiv thaiv cov nplaim taws thiab kub tau kis los ntawm kev sib kis, yog li ua rau ntsuas kub. Lub peev xwm thermoelectric (Kuj muaj nuj nqis) tsim los ntawm qhov ntsuas hluav taws xob (resistor) yog ces hloov mus rau qhov ntsuas hluav taws xob tsis sib haum thiab xa mus rau tus neeg ua haujlwm ntsuas. Cov ntsuas ua haujlwm ua haujlwm nrog tus nqi ntsuas kub.

Rwb thaiv tsev tsis kam: lub rwb thaiv tsev tsis kam ntawm cov cuab yeej ntsuas cov zis thiab lub tsev yuav tsum tsis txhob tsawg dua 50
Lub sijhawm teb cua sov:
Thaum muaj ib ruam hloov hauv qhov ntsuas kub, lub sijhawm xav tau rau cov zis tam sim no teeb meem los hloov mus rau 5 {% ntawm cov kev hloov pauv theem yog sawv cev los ntawm t}. 5. Thaum lub sij hawm cov ruam teb stabilization lub sij hawm ntawm qhov ntsuas kub (tsis kam tshaj)}}}}}. Thaum lub Kauj ruam teb tau teb ruaj khov lub sijhawm ntawm cov lus teb kub tsis tshaj lub sijhawm t0.5, lub sij hawm teb thermalple stabille yog siv raws li lub sijhawm ntsuas cua sov ntawm lub ntsuas;
Kev ua yuam kev yooj yim:
Qhov tseem ceeb ntawm cov twj paj nruag yuav tsum tsis pub tshaj qhov ua yuam kev ntawm cov theem pib ntawm thermocouple (resistor) thiab ntsuas kub.
