Ubusanzwe Ububiko bwa Platinum

I. Ibisobanuro

Ubushyuhe bwa Platinum Resistance Thermometero ikoreshwa mu kwishyurwa mu bushyuhe busanzwe bwa 13.8033k - 961.8°C, kandi ikoreshwa nkibisanzwe mugihe ugerageza ibipimo bitandukanye bya termometero hamwe nibisobanuro bihanitse bya termometero.Mubice byavuzwe haruguru ubushyuhe bwubushyuhe, burakoreshwa kandi muburyo bwo gupima ubushyuhe bwo hejuru.

Ubushuhe bwa The Platinum Resistance Thermometer bupima ubushyuhe ukurikije ibihe bihindagurika byubushyuhe bwo guhangana na platine.

Dukurikije amabwiriza ya ITS90, T.₉₀isobanurwa na platine ya termometero iyo ingingo eshatu (13.8033K) zingana na azote igera ku bushyuhe bwubushyuhe bwa feza.Ironderejwe ukoresheje itsinda ryibisabwa bisabwa gukonjesha hamwe nibikorwa byerekana kimwe no gutandukana kwubushyuhe bwa interpolation.

Ubushyuhe bwo hejuru bwagabanijwemo ibice byinshi hanyuma buhitamo gukora mubisanzwe muri zone yubushyuhe bwuburyo butandukanye bwimiterere ya termometero.

Reba ibisobanuro birambuye bya termometero biri kumeza ikurikira:

Icyitonderwa: Rtp ya termometero yavuzwe haruguru ni 25± 1.0Ω.Dimetero yo hanze yigituba cya quartz ni φ7 ± 0,6mm.uruganda rwacu narwo rukora platine ya termometero hamwe na zone yubushyuhe bwa 83.8058K ~ 660.323℃nkigikoresho cyibanze gikora.

II. Koresha Amakuru

1. Mbere yo gukoresha, ubanza, reba umubare wa termometero kugirango uhuze nicyemezo cyikizamini.

2. Iyo ukoresheje, ukurikije ikirango cya lug ya termometero ya wire ya termometero, huza neza neza.Lug① ya wire itukura ihujwe na terefone igezweho;lug③y'umuhondo w'umuhondo, kuri terefone igezweho;na lug②y'insinga z'umukara, kuri positif nziza nziza;lug④y'icyatsi kibisi, kubishobora kuba bibi.

Ibikurikira nurucacagu rwa termometero:

3. Ibiriho bigomba kuba 1MA ukurikije ibipimo byubushyuhe bwa termometero.

4. Kugirango uhuze ibikoresho byo gupima amashanyarazi ya termometero kugirango bipime ubushyuhe, potentiometero nkeya yo guhangana nicyiciro cya 1 hamwe na coil isanzwe yo mu cyiciro cya 0.1 cyangwa gupima ikiraro cyubushyuhe nyacyo kimwe nibindi bikoresho.Igikoresho cyuzuye cyo gupima amashanyarazi kigomba kwemezwa kugira sensibilité yo gutandukanya ihinduka rya Ohm ibihumbi icumi.

5. Mugihe cyo gukoresha, kubungabunga no gutwara, gerageza wirinde kunyeganyega gukabije kwa termometero.

6. Iyo ukoresheje icyiciro cya mbere Standard Platinum Resistance Thermometer kugirango ugerageze ubushyuhe bwicyiciro cya kabiri Standard Platinum Resistance Thermometer, igomba gukurikiza inzira yo kugenzura yemejwe nikigo cyigihugu gishinzwe gupima.

7. Ikizamini gisanzwe cya termometero kigomba gukorwa cyane ukurikije uburyo bwo kugenzura no kugenzura.
