Nigute ushobora kugenzura neza ikosa mugupima thermocouple?

Nigute wagabanya ikosa ryo gupimwa ryatewe no gukoresha thermocouples?Mbere ya byose, kugirango dukemure ikosa, dukeneye kumva icyateye ikosa kugirango dukemure neza ikibazo!Reka turebe impamvu nke zamakosa.

Ubwa mbere, menya neza ko thermocouple yashyizweho neza.Niba idashyizweho neza, hazabaho ikosa.Ibikurikira ningingo enye zo kwishyiriraho.
1. Ubujyakuzimu bwinjizwamo bugomba kuba byibuze inshuro 8 z'umurambararo wa tube irinda;umwanya uri hagati yigitereko gikingira nurukuta rwa thermocouple ntabwo wuzuyemo ibikoresho byiziritse, bizatera ubushyuhe bwinshi mu itanura cyangwa kwinjira mu kirere gikonje, kandi bigakora umuyoboro urinda thermocouple hamwe nu mwobo w’urukuta rw'itanura Icyuho kibujijwe no kubika ibikoresho nka icyondo cyangiritse cyangwa umugozi wipamba kugirango wirinde guhumeka umwuka ushushe nubukonje, bigira ingaruka kumupima wubushyuhe.
2. Impera ikonje ya thermocouple yegereye cyane itanura, kandi ubushyuhe bwigice cyo gupima ni hejuru cyane;
3. Kwishyiriraho thermocouple bigomba kugerageza kwirinda umurima ukomeye wa magnetique hamwe numuriro w'amashanyarazi ukomeye, bityo thermocouple na kabili y'amashanyarazi ntibigomba gushyirwaho kumuyoboro umwe kugirango wirinde amakosa yatewe no kwivanga.
4.Termocouples ntishobora gushyirwaho mubice bipimye gake gake.Iyo ukoresheje thermocouple kugirango upime ubushyuhe bwa gaze muri tube, thermocouple igomba gushyirwaho muburyo bwihuse kandi igahura na gaze.

Icya kabiri, mugihe ukoresheje thermocouple, ihinduka ryimikorere ya thermocouple nayo nimwe mumpamvu zamakosa:
1. Umwanda ukabije n'umunyu mwinshi hagati ya electrode ya thermocouple nurukuta rw'itanura bizatera insulisiyo mbi hagati ya electrode ya thermocouple nurukuta rw'itanura, ibyo ntibizatera gusa gutakaza ingufu z'amashanyarazi, ahubwo binabangamira, kandi rimwe na rimwe ikosa rishobora no kugera ku magana ya dogere selisiyusi.
2. Ikosa ryatewe no kurwanya ubushyuhe bwa thermocouple:
Kuba umukungugu cyangwa ivu ryamakara kumuyoboro urinda thermocouple byongera ubushyuhe bwumuriro kandi bikabuza gutwara ubushyuhe, kandi agaciro kerekana ubushyuhe kari munsi yagaciro nyako k'ubushyuhe bwapimwe.Noneho rero, komeza isuku ya thermocouple.
3. Amakosa yatewe nubusembure bwa thermocouples:
Inertia ya thermocouple ituma agaciro kerekana igikoresho kinyuma inyuma yimihindagurikire yubushyuhe bwapimwe, bityo thermocouples ifite itandukaniro rito cyane ryubushyuhe hamwe na diameter ntoya irinda igomba gukoreshwa bishoboka.Bitewe na hystereze, igipimo cyimihindagurikire yubushyuhe cyagaragajwe na thermocouple ni gito ugereranije n’ubushyuhe bw’itanura.Kubwibyo, kugirango bapime neza ubushyuhe, hagomba gutoranywa ibikoresho bifite ubushyuhe bwiza bwumuriro, kandi hagomba gutoranywa amaboko yo gukingira afite urukuta ruto na diameter ntoya imbere.Mu gupima ubushyuhe buhanitse, hifashishijwe insinga zambaye ubusa zidafite amaboko yo gukingira.

Muri make, ikosa ryo gupimwa rya thermocouple rishobora kugabanuka mubice bine: intambwe imwe nukugenzura niba thermocouple yashyizweho neza, intambwe ya kabiri nukugenzura niba insulation ya thermocouple yahinduwe, intambwe ya gatatu nukugenzura niba umuyoboro wa thermocouple urinda isuku, kandi intambwe ya kane ni Ikosa rya thermoelectric Ikosa ryatewe na inertia!
