The Standard Platinum Resistance Thermometer imagwiritsidwa ntchito polipira chiwongoladzanja cha kutentha kwa 13.8033k-961.8 ° C, ndipo imagwiritsidwa ntchito ngati muyeso poyesa mitundu yosiyanasiyana ya zoyezera kutentha ndi zoyezera kwambiri.Mkati mwa malo omwe ali pamwambawa, amagwiritsidwanso ntchito mwachindunji poyeza kutentha kwapamwamba kwambiri.

The Standard Platinum Resistance Thermometer imayesa kutentha motsatira kusinthasintha kwa kutentha kwa platinamu.

Mogwirizana ndi malamulo a ITS90, gulu la T₉₀Zimatanthauzidwa ndi thermometer ya platinamu pamene mfundo zitatu (13.8033K) za nayitrogeni zimafika pamlingo wozizira wa siliva.Imasonyezedwa pogwiritsa ntchito gulu lofunikira lomwe limatanthauzidwa kuzizira ndi ntchito yofotokozera komanso kupatuka kwa kutanthauzira kwa kutentha.

Kutentha kwapamwambaku kumagawidwa m'magawo angapo ndipo adaganiza zogwira ntchito moyenera mkati mwa sub-temperature ndi mitundu yosiyanasiyana ya ma thermometers.

Onani zoyezera mwatsatanetsatane patebulo ili pansipa:

Zindikirani: Rtp ya ma thermometers omwe ali pamwambawa ndi 25±1.0Ω.Kuzungulira kwakunja kwa machubu a quartz ndi φ7±0.6mm.fakitale yathu imapanganso thermometer ya platinamu ndi zone ya kutentha ya 83.8058K~660.323℃ monga chida chogwiritsira ntchito.

II.Gwiritsani Ntchito Zambiri

1. Musanagwiritse ntchito, choyamba, yang'anani nambala ya thermometer kuti igwirizane ndi satifiketi yoyesera.

2. Mukamagwiritsa ntchito, molingana ndi logo ya lug ya terminal waya wa thermometer, gwirizanitsani waya molondola.Lug① ya waya wofiyira imalumikizidwa ku terminal yomwe ilipo;lug③wawaya wachikasu, kupita kumalo omaliza opanda pake;ndi lug②wawaya wakuda, kupita kumalo omwe angathe kukhala abwino;lug④wawaya wobiriwira, kupita kumalo omwe angakhale opanda pake.

Nayi chidule cha thermometer:

3. Zamakono ziyenera kukhala 1MA molingana ndi kuyeza kwa gawo la kutentha kwa thermometer.

4. Kuti mufanane ndi chipangizo choyezera magetsi cha thermometer choyezera kutentha, potentiometer yotsika yotsika ya giredi 1 ndi kukana koyilo kwa giredi 0.1 kapena mlatho woyezera woyezera kutentha komanso zowonjezera ziyenera kugwiritsidwa ntchito.Seti yathunthu ya chipangizo choyezera magetsi iyenera kutsimikiziridwa kuti ili ndi chidwi chosiyanitsa kusintha kwa chikwi chimodzi cha Ohm.

5. Panthawi yogwiritsira ntchito, kusunga ndi kuyendetsa, yesetsani kupewa kugwedezeka kwakukulu kwa makina a thermometer.

6. Mukamagwiritsa ntchito giredi yoyamba ya Standard Platinum Resistance Thermometer kuyesa kutentha kwa kalasi yachiwiri ya Standard Platinum Resistance Thermometer, muyenera kutsatira njira zotsimikizira zovomerezeka ndi National Measurement Bureau.

7. Kuyesa kwanthawi zonse kwa thermometer kuyenera kuchitidwa mwamphamvu molingana ndi njira ndi malamulo otsimikizira.
