Thermostat ni iki?
Ibikoresho bigenzura ubushyuhe bifite amazina atandukanye, nko guhindura ubushyuhe, ibirinda ubushyuhe n'ibigenzura ubushyuhe. Dukurikije ihame ry'imikorere, bishobora kugabanywamo thermostat yo mu bwoko bwa jump type, thermostat yo mu bwoko bwa liquid type, thermostat yo mu bwoko bwa pressure na thermostat yo mu bwoko bwa electronic. Mu bikoresho bigezweho byo kugenzura inganda, thermostat yo mu bwoko bwa digital ni yo ikoreshwa cyane. Dukurikije imiterere, thermostat yo mu bwoko bwa tableau ishobora kugabanywamo thermostat yo mu bwoko bwa "integrated temperature controller" n'iya "modular temperature controller".
Ibipimo by'ingufu (thermometers) ni ibihe?
Igipimo cy'ubushyuhe ni igice gihindura ikimenyetso cy'ubushyuhe mo ikimenyetso cy'amashanyarazi, kandi gikunze gushyirwa mu gice cyo gutahura ikintu gigenzurwa kugira ngo gikurikirane agaciro k'ubushyuhe bwacyo. Mu rwego rwo kugenzura imikorere y'inganda, ibipimo bikunze gukoreshwa birimo ibipimo bya thermocouples, ibipimo by'ubushyuhe, ibipimo by'ubushyuhe n'ibipimo bitanyuranaho. Muri byo, bitatu bya mbere ni ibipimo by'ubushyuhe.
1. Thermocouple
Ihame ryo gupima ubushyuhe bwa thermocouples rishingiye ku ngaruka za Seebeck (ingaruka za thermoelectric). Iyo ibyuma bibiri by'ibikoresho bitandukanye (ubusanzwe ni ukuvuga ibyuma bikoresha amashanyarazi cyangwa semiconductors, nka platine-rhodium, nickel-chromium-nickel-silicon n'ibindi bikoresho bifatanye) bikora umuzenguruko ufunze kandi bigashyira ubushyuhe butandukanye ku mpera zabyo ebyiri zihuza, imbaraga za electromotive zikorwa hagati y'ibyuma byombi. Umuzenguruko nk'uwo witwa "thermocouple," mu gihe ibyuma bibiri byitwa "electrode y'ubushyuhe," naho imbaraga za electromotive zikomokaho zitwa "imbaraga za thermoelectric motivation". Thermocouples zirangwa n'urwego rwazo rwo gupima ubushyuhe, igisubizo cyihuse cy'ubushyuhe, no kudahindagurika cyane.
2. Ubudahangarwa bw'ubushyuhe
Ubudahangarwa bw'ubushyuhe ni igice gihindura ikimenyetso cy'ubushyuhe mo ikimenyetso cy'amashanyarazi, kandi ihame ryacyo rishingiye ahanini ku miterere y'impinduka z'ubudahangarwa bw'icyuma bitewe n'ubushyuhe. By'umwihariko, ibirwanya ubushyuhe bifashisha iyi miterere y'icyuma kugira ngo bipime ubushyuhe.
Mu kugenzura inganda, ubwoko bukunze gukoreshwa bwo kurwanya ubushyuhe burimo platine, umuringa na nikeli. Muri zo, kurwanya platine ni byo bikunze gukoreshwa cyane. Kurwanya ubushyuhe bifite imiterere myiza y'ubushyuhe, imikorere ihamye n'ubuziranenge bwo hejuru mu rwego rw'ubushyuhe busanzwe. Kubwibyo, mu gihe ubushyuhe buri hagati, nta guhindagurika no kudahindagurika cyane, gukoresha platine ni byo bikunze gukoreshwa.
3. Thermistor
Thermistor ni igice gihindura ikimenyetso cy'ubushyuhe mo ikimenyetso cy'amashanyarazi, kandi ihame ryacyo rishingiye ahanini ku miterere y'ubudahangarwa bw'ibikoresho bya semiconductor buhinduka bitewe n'ubushyuhe. By'umwihariko, ibikoresho bya semiconductor bifashisha iyi miterere ya semiconductors kugira ngo bapime ubushyuhe. Ugereranyije n'ubudahangarwa bw'ubushyuhe, ubushobozi bwa thermistor buhinduka cyane bitewe n'impinduka z'ubushyuhe, bityo urwego rwayo rwo gupima ubushyuhe ni ruto cyane (-50~350℃).
Thermistors zigabanyijemo NTC thermistors na PTC thermistors. Thermistors za NTC zifite ikigereranyo cy'ubushyuhe kiri hasi, kandi agaciro kazo ko guhangana kagabanuka uko ubushyuhe bwiyongera. Thermistors za PTC zifite ikigereranyo cy'ubushyuhe kiri hasi, kandi agaciro kazo ko guhangana kaziyongera uko ubushyuhe bwiyongera. Kubera imiterere yazo yihariye y'ubushyuhe, thermistors zifite uburyo bwinshi bwo gukoresha mu gupima ubushyuhe, kugenzura byikora, ibikoresho by'ikoranabuhanga n'ibindi.
