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 uvavanya iindidi ze-thermometers eziqhelekileyo kunye ne-high-precision thermometers.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:
| Uhlobo | Ukuhlelwa | Indawo yobushushu obufanelekileyo | Ubude bokusebenza(mm) | Ubushushu |
| WZPB-1 | I | 0 ~ 419.527℃ | 470±10 | Phakathi |
| WZPB-1 | I | -189.3442℃~419.527℃ | 470±10 | Igcwele |
| WZPB-2 | II | 0 ~ 419.527℃ | 470±10 | Phakathi |
| WZPB-2 | II | -189.3442℃~419.527℃ | 470±10 | Igcwele |
| WZPB-7 | I | 0 ~ 660.323℃ | 510±10 | Phakathi |
| WZPB-8 | II | 0 ~ 660.323℃ | 510±10 | Phakathi |
Qaphela: I-Rtp yezi themometha zingentla yi-25±1.0Ω.I-diameter yangaphandle yeetyhubhu ze-quartz yi-φ7±0.6mm.ifektri yethu iphinda ivelise i-thermometer yeplatinam kunye nendawo yobushushu ye-83.8058K~660.323℃ njengesixhobo esisisiseko esisebenzayo.
II.Sebenzisa Ulwazi
1. Ngaphambi kokusebenzisa, okokuqala, khangela 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;ilug③yocingo olutyheli, ukuya kwitheminali ekhabayo yangoku;kunye nelug② yocingo olumnyama, ukuya kwitheminali enokubakho ephozithivu;ilug④yocingo oluluhlaza, ukuya kwitheminali enokubakho engalunganga.
Oku kulandelayo luluhlu lwethemomitha:
3. Ixesha elikhoyo kufuneka libe yi-1MA ngokwemilinganiselo yecandelo lobushushu le-thermometer.
4. Ukuhambelana nesixhobo sokulinganisa sombane sethemometha yokulinganisa ubushushu, i-potentiometer ephantsi yokumelana nebanga loku-1 kunye nokumelana nomgangatho we-coil webanga le-0.1 okanye ibhulorho echanekileyo yokulinganisa ubushushu kunye nezixhobo kufuneka zisetyenziswe.Isethi epheleleyo yesixhobo sokulinganisa umbane kufuneka siqinisekiswe ukuba sinovakalelo lokwahlula ukutshintshwa kwe-Ohm enye yeshumi lamawaka.
5. Ngethuba lenkqubo yokusebenzisa, ukugcinwa kunye nokuthutha, zama ukuphepha 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 lwethemometha kufuneka lwenziwe ngokungqongqo ngokwemigaqo nemigaqo yokuqinisekisa efanelekileyo.
