Ubusanzwe Ububiko bwa Platinum
Ubusanzwe Ububiko bwa Platinum
I.Ibisobanuro
Ikigereranyo cya Platinum Resistance Thermometer ikoreshwa mu kwishyurwa mu bushyuhe buri hagati ya 13.8033k - 961.8 ° C, kandi ikoreshwa nkibisanzwe mugihe ugerageza ibipimo bitandukanye bya termometero hamwe na termometero zisobanutse neza.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:
| Andika | Ibyiciro | Agace keza k'ubushyuhe | Uburebure bw'akazi (mm) | Ubushyuhe |
| WZPB-1 | I | 0 ~ 419.527 ℃ | 470 ± 10 | Hagati |
| WZPB-1 | I | -189.3442 ℃ ~ 419.527 ℃ | 470 ± 10 | Byuzuye |
| WZPB-2 | II | 0 ~ 419.527 ℃ | 470 ± 10 | Hagati |
| WZPB-2 | II | -189.3442 ℃ ~ 419.527 ℃ | 470 ± 10 | Byuzuye |
| WZPB-7 | I | 0 ~ 660.323 ℃ | 510 ± 10 | Hagati |
| WZPB-8 | II | 0 ~ 660.323 ℃ | 510 ± 10 | Hagati |
Icyitonderwa: Rtp ya tometrometero yavuzwe haruguru ni 25 ± 1.0Ω.Umurambararo wo hanze wigituba cya quartz ni φ7 ± 0,6mm.
II.Koresha Amakuru
1. Mbere yo gukoresha, ubanza, reba nimero ya termometero kugirango uhuze nicyemezo cyibizamini.
2. Mugihe ukoresheje, ukurikije ikirango cya lug ya terefone ya termometero, huza neza neza.Lug① ya wire itukura ihujwe na terefone igezweho;lug③ ya wire yumuhondo, kuri terefone igezweho;na lug② ya wire yumukara, kubishobora kuba byiza;lug④of 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 kwihanganira icyiciro cya 1 hamwe na coil isanzwe irwanya icyiciro cya 0.1 cyangwa gupima ikiraro cyuzuye cy'ubushyuhe 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, ugomba gukurikiza inzira yo kugenzura yemejwe nikigo cyigihugu gishinzwe gupima.
7. Ikizamini gisanzwe cya termometero kigomba gukorwa cyane ukurikije uburyo bwo kugenzura no kugenzura.
