Dab tsi yog qhov sib txawv ntawm cov ntsiab cai ua haujlwm ntawm thermocouples thiab bimetallic kub?

Qhov sib txawv hauv cov qauv ua haujlwm ntawm thermocouples thiab bimetallic kub

Muaj ob hom sib txawv, ib qho yog tib cov hlau thiab lwm yam yog ob qho sib txawv.

Thermocouples yog cov khoom siv hluav taws xob ua tau siv cov nyhuv thermoelectric, thaum lub sij hawm bimetallic thermometers siv cov nqi sib txawv nrog cov nqi sib txawv
Tus txheej txheem yooj yim ntawm thermocouple kub ntsuas yog tias ob tug cwj pwm uas muaj sib txawv ua daim ntawv sib txawv ntawm Circuit Court. Thaum muaj qhov ntsuas kub ntawm ob qho kawg, tam sim no yuav ntws los ntawm Circuit Court, thiab yuav muaj ib lub zog hluav taws xob - nruab nrab ntawm ob xaus, uas yog hu ua cov nyhuv pom. Ob homogeneous tus cwj pwm nrog cov sib txawv yog thermoelectric siv hluav taws xob, nrog rau qhov kub siab kawg li kev ua haujlwm kawg thiab qhov chaw pub dawb, uas feem ntau yog nyob ntawm qhov kub tsis tu ncua. Tsim cov lus ntsuas hluav taws xob thermocouple raws li kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub; Lub rooj ntsuas hluav taws xob yog tau nyob hauv qhov xwm txheej ntawm qhov xaus pub dawb ntawm 0 thermocouces muaj cov rooj ntsuas hluav taws sib txawv.

Cov pas ntsuas bimetallic siv hlau thiab tooj liab, ob co me ntawm cov qauv sib txawv ntawm kev nthuav dav, los ntawm cov khoom siv hluav taws xob sib txawv thiab kev cog lus ntawm cov hlau. Thaum qhov kub nce, lub pob tw bimetallic yuav khoov thiab tsim kev nyeem!

Tus pas ntsuas hluav taws xob bimetallic siv ob co cofficients nrog cov kab sib txawv ntawm cov linear nthuav, nrog ib qho kawg tsau. Thaum qhov kub hloov pauv, lub thermal expansion ntawm ob cov hlau sib txawv, uas tsav tus pointer kom qhia qhov kub. Qhov no yog tus pas ntsuas kub bimetallic, raws li qhia hauv daim duab ntawm nplooj ntawv dhau los. Qhov ntsuas kub yog {-80 ~ 600C, uas haum rau kev ntsuas kub hauv kev lag luam nrog cov kev xav tau tsawg. Bimetallic txheeb xyuas, raws li qhov kub siab pom kev, tseem siv tau rau kev tswj kom kub kub.

Qhov kev sojntsuam siv nyob rau hauv kev xaiv ntawm bimetallic thermometers hais txog ntsuas ntsuas qhov ntev ntsuas qhov ntev.
Rigation qws hais txog qhov ntev ntawm cov xov txuas los yog flange rau hauv qab qhov kev sojntsuam, tseem hu ua qhov tob tob.
Kev tsis muaj feem cuam tshuam txog kev sojntsuam:
1. Kev sojntsuam inch (tuab)
2. Kev nkag siab tob (ntev)
3. Kev sojntsuam qws khoom siv
