Dab tsi yog qhov tsis ua tiav tsis ua hauj lwm ntawm thenomena?

Qhov tsis ua hauj lwm tsis ua hauj lwm tshwm sim ntawm thermocouples feem ntau yog cov hauv qab no:
Qhov ntsuas qhov tsis raug
Qhov kub ntxhov: Muaj ib qho kev sib txawv loj ntawm ntsuas kub thiab ntsuas kub thiab txias} qhov no yuav tsis haum rau kev ntsuas kub nyob rau hauv ib puag ncig cua sov; lossis cov teeb tsa kev teeb tsa ntawm cov thermocouple yog tsis tsim nyog, thiab lub hom phiaj kub tsis yog ntsuas, ua rau muaj huab cua tsis ruaj khov, ua rau muaj kev hloov pauv loj hauv kev ntsuas ntsuas.
Kev tsis pom tseeb: Tom qab siv ntev, qhov tseeb ntawm Thermocouple yog vim tias cov khoom siv ntawm thermocouple tej zaum yuav corroded, ua rau muaj kev ntsuas yuam kev .
Cov paib tsis ruaj khov
Teeb liab convedumized: lub logoelectric muaj peev xwm tso zis tawm los ntawm thermocouple terminals, uas ua rau kev sib chstable tsis ruaj, uas ua rau muaj kev sib cuag teeb meem; lossis cov hlau them nyiaj puas lawm, tsim cov paib tsis ruaj khov nyob rau hauv sab nraud cuam tshuam rau.
Signal jump: The output signal suddenly jumps by a large amplitude. There may be a local short circuit or open circuit inside the thermocouple, such as damage to the insulation layer of the thermocouple, resulting in a short circuit between the electrodes, or the electrode is broken, resulting in an open circuit, which will cause abnormal signal jumps.
Teb lub sijhawm yog ntev dhau lawm
Thermal inertia yog loj: Thermocouple cov lus teb rau qhov kub thiab txias kev hloov pauv ntawm lub sijhawm tuab lossis siv sijhawm tsis zoo; los yog thermocouple yog qhov raug ntsia tsis zoo, xws li tsis muaj qhov ntsuas tsis txaus, uas ua rau nws tsis muaj peev xwm hloov qhov ntsuas kub ntawm kev ntsuas ntsuas kub.
Txawv txav thermoelectric muaj peev xwm tawm
Tsis muaj cov khoom siv hluav taws xob thermoelle muaj tsis muaj qhov tso zis thermoelectric muaj qhov kub thiab txias rau qhov kub thiab txias. los yog thermocouple tau raug puas ntsoog, xws li electrode hlawv tawm, sab hauv circh breaking, thiab lwm yam.
Thermoelectric muaj peev xwm thim rov qab: cov zis thermoelectric muaj peev xwm sib txuas lus nyob rau hauv kev ntsuas hluav taws xob, los yog ua rau lub teeb liab reversal.
Cov tsos puas tsuaj
Kev puas tsuaj rau Lub Tes Tsho Tiv Thaiv: Lub Tsho Tiv Thaiv ntawm Thermocouple yog nthuav tawm cov khoom siv sab nraud, uas yog kev cuam tshuam rau kev ntsuas qhov tseeb thiab kev pabcuam lub neej .
Cov Khoom Siv Hluav Taws Xob lossis deformation: Qhov saum npoo ntawm Thermocroup electrode cov chaw ua haujlwm ntawm cov khoom siv hluav taws xob, lossis deformation ntawm cov khoom siv hluav taws xob ntau ntxiv, uas yuav cuam tshuam rau kev ua haujlwm sab nraud ntawm lub zog ntawm lub thermocouple.
