Thermocouples zifite ubushyuhe bwinshi
Ibisobanuro by'igicuruzwa
Ibyuma bipima ubushyuhe (bizwi kandi nka thermocouples zishyushya amabuye y'agaciro) ni ibikoresho bipima ubushyuhe mu nganda bikoreshwa mu buryo buhambaye.Ubwoko bw'ingenzi burimo K, N, E, J, T, na S, ishobora gupima ubushyuhe kuva kuri -200°C kugeza kuri 1300°C ku binyabutabire, umwuka, imyuka, n'ubuso bukomeye.
Imashini zikoresha thermocouples zikoreshwa cyane mu nganda nka peteroli, imiti, ingufu, ikoranabuhanga mu byuma, n'indege.
Thermocouple ifite sheath ni sensor y'ubushyuhe ikorwa binyuze mu buryo bwo gufungana, ihuza insinga za thermocouple, ibikoresho bikingira ubushyuhe, n'icyuma gikingira. Ifite ubushobozi bwo koroha, irwanya ubushyuhe bwinshi, kandi ihangana n'umuvuduko mwinshi. Ugereranyije na thermocouple zisanzwe, ubwoko bwa sheath bufite umurambararo muto kandi bushobora kunyeganyega cyane, bigatuma ikwiriye gupimwa ubushyuhe ahantu hato kandi hagoye kuhagera, mu gihe inatanga igisubizo cyihuse.
Ihame ry'imikorere ya Thermocouples zifunze
Ihame ryo gupima ubushyuhe bwa thermocouple ifite sheath ni rimwe n’iry’iyo thermocouple isanzwe, hashingiwe ku ngaruka za Seebeck. Iyo hari itandukaniro ry’ubushyuhe hagati y’aho gupimira (impera ishyushye) n’aho ihuriro ry’aho rihurira (impera ikonje/impera yo guhuza), imbaraga za electromotive thermal (EMF) zikorwa mu ruziga rwakozwe n’ibyuma bibiri bitandukanye. Mu gupima iyi EMF y’ubushyuhe, ubushyuhe ku ihuriro ry’aho gupimira bushobora kumenyekana.
Ibiranga thermocouples za sheathed
• Igihe cyo gusubiza ubushyuhe vuba n'ikosa rito rijyanye n'ikirere
• Ingufu nyinshi za mekanike, zirwanya igitutu, impanuka, no gutigita
• Gushyiraho byoroshye bitewe no guhindagurika kw'imashini
• Irwanya ubushyuhe bwinshi n'ingufu
Imikoreshereze ya Thermocouples zo mu bwoko bwa Sheathed
• Igenzura ry'imikorere y'inganda:Gukurikirana no kugenzura ubushyuhe mu miyoboro, imashini zitanga ingufu, n'ibindi bikoresho mu nganda zikora peteroli, imiti n'ingufu.
• Ikoreshwa mu bushyuhe bwinshi no mu byuma:Gupima ubushyuhe mu bikoresho bishyuha cyane nk'amatanura n'amatanura yo guturika mu nganda z'ibyuma na sima.
• Ibidukikije byihariye:Gupima ubushyuhe bwihuse cyangwa ahantu hafunganye mu igerageza rya moteri z'indege n'ubushakashatsi bwa siyansi.
• Ibisabwa ku buryo busaba imbaraga:Ahantu hagoye ho gukorera harimo guhindagura, umuvuduko mwinshi, ibisabwa kugira ngo hashyirweho ibintu bipfukamye, cyangwa gukenera igisubizo cyihuse.
Ubwoko bw'Uburyo bwo Gupima Thermocouple
Ubwoko bw'ubutaka:Aho gupimisha hasuzumirwa ku gikoresho, bigatanga igisubizo cyihuse. Ariko, ntabwo bikwiriye gukoreshwa mu byuma bitwara amazi cyangwa byangiza.
Ubwoko budafite umuyoboro:Aho gupimisha hashyirwa amashanyarazi aturutse mu gipangu. Hatanga igisubizo gito ariko gifite ubudahangarwa bukomeye, ni bwo bwoko bukoreshwa cyane, kandi bumara igihe kirekire.
Ubwoko bwagaragajwe:Aho gupimisha hagaragara hanze y'icyuma, bigatanga igisubizo cyihuse cyane. Ariko, insinga zishobora kwangirika, bigatuma zikoreshwa mu byuma byumye kandi bitangiza.
Ubwoko bwa Thermocouples
| Ubwoko bwa Thermocouple | Ingano yo gupima | Icyiciro cya I cy'Uburinganire | Icyiciro cya II cy'Ubuziranenge |
| K | Ubushyuhe -40 kugeza 1200℃ | ± 1.5℃ | ± 2.5℃ |
| N | Ubushyuhe -40 kugeza 1200℃ | ± 1.5℃ | ± 2.5℃ |
| E | -40 kugeza 900℃ | ± 1.5℃ | ± 2.5℃ |
| J | -40 kugeza kuri 750℃ | ± 1.5℃ | ± 2.5℃ |
| T | -40 kugeza 1000℃ | ± 0.5℃ | ± 1.0℃ |
| S | Ubushyuhe buri hagati ya 0 na 1600℃ | ± 1.0℃ | ± 1.5℃ |
