Dab tsi yog qhov txawv ntawm Grounded thiab Ungrounded Kub Khiav Thermocouples

Ob hom txheej txheem txheej txheem ntawm cov kub khiav thermocouples yog hom kev sib tshuam hauv av thiab tsis muaj kev sib tshuam, uas txawv ntawm kev tsim kho sab hauv, kub teb ceev, tiv thaiv- kev ua haujlwm corrosion, thiab kev ua haujlwm tsim nyog. Ntau tus neeg siv pom tias nws nyuaj rau kev pom ntawm ob hom, uas ua rau kev xaiv tsis raug, cov lus teb rau qhov kub thiab txias, yooj yim teeb liab cuam tshuam, thiab lub neej ua haujlwm luv.

Qhov kub kawg alloy kev twb kev txuas ntawm grounded thermocouples yog ncaj qha welded rau cov hlau sheath. Vim hais tias ntawm lub luv luv tshav kub conduction channel thiab incredibly ceev kub sensing teb ceev, tus kub khiav qhov kub hloov tam sim ntawd yuav ceev ceev. Lawv tsim nyog rau cov kab ke ntawm lub rooj vag valve uas xav tau kev tawm tswv yim kub, siab - voj voog, siab - nrawm molding pwm, thiab nozzle qhov rooj ntsuas kub ntsuas. Txawm li cas los xij, lub teeb liab kev ruaj ntseg yog me ntsis tsis zoo nyob rau hauv complex electromagnetic ib puag ncig vim hais tias ntawm ncaj qha conduction ntawm cov hlau sheath thiab alloy hlws ris, uas ua rau nws raug rau sab nraud electromagnetic cuam tshuam thiab generates stray tam sim no.

Ungrounded thermocouples muaj cov qauv sib cais, nrog rau siab - purity rwb thaiv tsev muab tub lim tag nrho sealing thiab sib cais cov hlau kub kub kawg ntawm txheej hlau sheath. Nws tuaj yeem ua tiav cov suab nrov ntawm electromagnetic thiab stray tam sim no, muaj zog tiv thaiv - muaj peev xwm cuam tshuam thiab kev ua haujlwm siab rwb thaiv tsev, thiab xa cov teeb liab kub tsis tu ncua thiab tsis muaj bouncing. Nws yog qhov zoo tagnrho rau kev kho mob siab -cov pwm precision uas xav tau cov ntaub ntawv ntsuas kub tsis txaus ntseeg, kev cob qhia ntse nrog kev cuam tshuam loj heev, thiab ntau- kab noj hniav ntom ntom pwm pwm. Nws cov drawbacks muaj xws li ib tug me ntsis ntev tshav kub conduction txoj kev thiab ib tug qeeb qeeb kub teb lub sij hawm tshaj lub grounded hom.

Nyob rau hauv cov nqe lus ntawm corrosion kuj thiab kev pab cuam lub neej, ib tug ungrounded tag nrho insulated kaw qauv muaj ib tug ntev kev pab cuam lub neej, yog ntau nyuaj ua rau sab hauv oxidation thiab luv luv Circuit Court tsis ua hauj lwm, thiab yuav zoo dua cais qhov yaig ntawm corrosive volatile gas thiab damp roj pos huab. Hom hauv av yog zoo dua rau cov txheej txheem kev khiav hauj lwm nrog ncaj nraim ib puag ncig thiab xav tau lub sij hawm teb. Kev xaiv kom raug thiab kev siv tag nrho ntawm qhov kub khiav qhov system tswj qhov kub thiab txias tuaj yeem ua tiav los ntawm kev ua kom raug qhov sib txawv ntawm cov qauv thiab cov xwm txheej ntawm cov khoom siv hauv av thiab cov thermocouples.333
