I-Standard Platinum Resistance Thermometer

I. Inkcazo

I-Standard Platinum Resistance Thermometer isetyenziselwa imbuyekezo kwiqondo lokushisa eliqhelekileyo le-13.8033k-961.8°C, kwaye isetyenziswe njengomgangatho xa kuhlolwa iindidi zeethemomitha ezisemgangathweni kunye neethemomitha ezichanekileyo.Ngaphakathi kwendawo yokushisa engentla, isetyenziselwa ngokuthe ngqo ukulinganisa ubushushu bokuchaneka okuphezulu.

I-Standard Platinum Resistance Thermometer ilinganisa iqondo lobushushu ngokuguquguquka rhoqo lobushushu bokumelana neplatinam.

Ngokuhambelana nemigaqo ye-ITS90, i-T₉₀ichazwa yithemometha yeplatinam xa inqaku eliphindwe kathathu (13.8033K) lebhalansi yenitrogen ifikelela kuluhlu lobushushu bendawo yokukhenkceza yesilivere.Isalathiswa ngokusebenzisa iqela lendawo yokukhenkceza efunekayo echaziweyo kunye nomsebenzi wereferensi kunye nomsebenzi wokutenxa we-interpolation yobushushu.

Lo mmandla wobushushu ungentla wohlulwe ngokwahlukeneyo kwaye wagqiba ekubeni usebenze ngokuqhelekileyo ngaphakathi kwendawo yobushushu obuphantsi ngeendlela ezahlukeneyo zolwakhiwo lweethemomitha.

Bona ithemometha eneenkcukacha kwitheyibhile engezantsi:

Qaphela: I-Rtp yezi themometha zingentla ngama-25±1.0Ω.I-diameter yangaphandle yeetyhubhu zequartz yi-φ7±0.6mm.ifektri yethu iphinda ivelise i-thermometer yeplatinam kunye nendawo yokushisa ye-83.8058K ~ 660.323℃njengesixhobo esisisiseko esisebenzayo.

II. Sebenzisa Ulwazi

1. Ngaphambi kokusebenzisa, okokuqala, jonga inombolo yethemometha ukuba ihambelane nesatifikethi sovavanyo.

2. Xa usebenzisa, ngokwe-logo ye-lug yetheminali yocingo lwe-thermometer, qhagamshela ucingo ngokuchanekileyo.I-lug① yocingo olubomvu luqhagamshelwe kwitheminali yangoku evumayo;ilugi③yocingo olutyheli, ukuya kwitheminali ekhabayo yangoku;kunye ne lug②yocingo olumnyama, ukuya kwitheminali enokubakho;ilugi④yocingo oluluhlaza, ukuya kwitheminali enokubakho engalunganga.

Oku kulandelayo luluhlu lwethemomitha:

3. Ikhoyo ngoku kufuneka ibe yi-1MA ngokwemilinganiselo yecandelo lobushushu le-thermometer.

4. Ukuthelekisa isixhobo sokulinganisa umbane sethemometha yokulinganisa ubushushu, i-potentiometer ephantsi yokumelana nebanga loku-1 kunye nokumelana nomgangatho wekhoyili webanga le-0.1 okanye ibhulorho yokulinganisa echanekileyo yobushushu kunye nezixhobo kufuneka zisetyenziswe.Isethi epheleleyo yesixhobo sokulinganisa umbane kufuneka siqinisekiswe ukuba sinovakalelo lokwahlula ukutshintshwa kwe-Ohm enye yeshumi lamawaka.

5. Ngexesha lenkqubo yokusebenzisa, ukugcinwa kunye nokuthutha, zama ukunqanda ukunyakaza okunzima komatshini we-thermometer.

6. Xa usebenzisa i-Standard Standard Platinum Resistance Thermometer ukuvavanya ubushushu bebanga lesibini i-Standard Platinum Resistance Thermometer, kufuneka ilandele iinkqubo zokuqinisekisa ezivunywe yi-National Measurement Bureau.

7. Uvavanyo oluqhelekileyo lwe-thermometer kufuneka lwenziwe ngokungqongqo ngokwemigaqo kunye nemigaqo yokuqinisekisa efanelekileyo.
