Thermometer yePlatinum Resistance
Thermometer yePlatinum Resistance
I.Tsananguro
Thermometer yeStandard Platinum Resistance inoshandiswa kutsiva tembiricha ye13.8033k—961.8°C, uye inoshandiswa seyero pakuyedza mathermometer akasiyana-siyana uye mathermometer akanyatsojeka. Mukati menzvimbo yetembiricha iri pamusoro, inoshandiswawo zvakananga kuyera tembiricha yekururama kwakanyanya.
Thermometer yeStandard Platinum Resistance inoyera tembiricha zvichienderana nekuchinja-chinja kwetembiricha yekudzivirira yeplatinum.
Zvichienderana nemitemo yeITS90, T90Inotsanangurwa ne platinum thermometer kana triplepoint (13.8033K) ye nitrogen balance yasvika padanho rekupisa re sirivha. Inoongororwa nekushandisa boka re demand defined freezing point uye reference function pamwe ne deviation function ye interpolation ye temperature.
Nzvimbo yekupisa iri pamusoro apa yakakamurwa kuita nzvimbo dzakasiyana-siyana uye yakasarudzwa kushanda zvakajairika munzvimbo yekupisa kudiki nemarudzi akasiyana-siyana echimiro chethermometers.
Ona ma thermometers akadzama ari patafura iri pazasi:
| Rudzi | Kupatsanura | Nzvimbo yekupisa yakakodzera | Kureba kwekushanda (mm) | Tembiricha |
| WZPB-1 | I | 0~419.527℃ | 470±10 | Pakati nepakati |
| WZPB-1 | I | -189.3442℃~419.527℃ | 470±10 | Yakazara |
| WZPB-2 | II | 0~419.527℃ | 470±10 | Pakati nepakati |
| WZPB-2 | II | -189.3442℃~419.527℃ | 470±10 | Yakazara |
| WZPB-7 | I | 0~660.323℃ | 510±10 | Pakati nepakati |
| WZPB-8 | II | 0~660.323℃ | 510±10 | Pakati nepakati |
Cherechedza: Rtp yemathermometers ari pamusoro apa i25±1.0Ω. Dhayamita yekunze yemachubhu equartz iφ7±0.6mm. Fekitori yedu inogadzirawo thermometer yeplatinum ine tembiricha ye83.8058K~660.323℃ sechishandiso chepakutanga chinoshanda.
II.Shandisa Ruzivo
1. Usati washandisa, chekutanga, tarisa nhamba yethermometer kuti ienderane negwaro rekuyedza.
2. Paunenge uchishandisa, zvichienderana nechiratidzo che lug che thermometer wire terminal, batanidza waya nemazvo. Lug① yewaya tsvuku yakabatana ne current positive terminal; lug③yewaya yeyero, kune current negative terminal; uye lug②yewaya nhema, kune potential positive terminal; lug④yewaya yegirini, kune potential negative terminal.
Zvinotevera ndizvo zvakaita thermometer:
3. Kuyerera kwemvura kunofanira kuva 1MA zvichienderana nekuyera kwechikamu chekupisa chethermometer.
4. Pakuenzanisa mudziyo wekuyera wemagetsi wethermometer yekuyera tembiricha, potentiometer ine resistance yakaderera yegiredhi 1 uye standard coil resistance yegiredhi 0.1 kana bhiriji rekuyera tembiricha chaiyo pamwe chete nezvimwe zvinoshandiswa zvinofanira kushandiswa. Seti yakazara yemudziyo wekuyera wemagetsi inofanira kuvimbiswa kuti ine sensitivity yekusiyanisa shanduko ye10000 Ohm.
5. Munguva yekushandisa, kuchengetedza uye kutakurwa, edza kudzivirira kudedera kwakanyanya kwethermometer.
6. Pakushandisa Standard Platinum Resistance Thermometer yegiredhi rekutanga kuyedza tembiricha yeStandard Platinum Resistance Thermometer yegiredhi rechipiri, inofanirwa kutevedzera nzira dzekusimbisa dzakatenderwa neNational Measurement Bureau.
7. Kuongororwa kwethermometer nguva dzose kunofanirwa kuitwa zvakasimba zvichienderana nemitemo yekuongorora yakakodzera.
