Standard Platinum Resistance Thermometer

I. Kufotokozera

The Standard Platinum Resistance Thermometer imagwiritsidwa ntchito polipira mulingo wa kutentha wa 13.8033k—961.8°C, ndipo amagwiritsidwa ntchito ngati muyezo poyesa zoyezera zoyezera zosiyanasiyana komanso zoyezera 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:

Chidziwitso: Rtp ya zoyezera zomwe zili pamwambapa ndi 25±1.0Ω.Kuzungulira kwakunja kwa machubu a quartz ndi φ7±0.6mm.fakitale yathu imapanganso thermometer ya platinamu ndi malo otentha a 83.8058K ~ 660.323℃monga chida choyambirira chogwirira ntchito.

II. Gwiritsani Ntchito Zambiri

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

2. Mukamagwiritsa ntchito, malinga ndi logo ya lug ya thermometer, gwirizanitsani waya molondola.Lug① ya waya wofiyira imalumikizidwa ku terminal yomwe ilipo;gulu③wa waya wachikasu, kupita ku terminal yaposachedwa;ndi lug②wa waya wakuda, kupita ku terminal yabwino;gulu④wa waya wobiriwira, kupita ku terminal yomwe ingakhale yolakwika.

Nayi chidule cha thermometer:

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

4. Pofananiza chipangizo choyezera chamagetsi cha thermometer choyezera kutentha, potentiometer yotsika ya giredi 1 ndi kukana koyilo kokhazikika kwa giredi 0.1 kapena mlatho 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. Pogwiritsa ntchito, kusunga ndi kunyamula, 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 zotsimikizira ndi malamulo oyenera.
