I-Standard Platinum Resistance Thermometer
I-Standard Platinum Resistance Thermometer
I.Incazelo
I-Standard Platinum Resistance Thermometer isetshenziselwa isinxephezelo ebangeni lokushisa elijwayelekile elingu-13.8033k—961.8°C, futhi isetshenziswa njengendinganiso lapho kuhlolwa izinhlobonhlobo zamathemometha ajwayelekile namathemometha anemba kakhulu.Ngaphakathi kwendawo yokushisa engenhla, iphinde isetshenziselwe ukukala izinga lokushisa lokunemba okuphezulu.
I-Standard Platinum Resistance Thermometer ikala izinga lokushisa ngokuvumelana nokushintshashintsha kwezinga lokushisa lokumelana neplatinamu.
Ngokuhambisana nemithethonqubo ye-ITS90, i-T90ichazwa ithemometha yeplatinamu lapho iphoyinti eliphindwe kathathu (13.8033K) lebhalansi ye-nitrogen ifinyelela ebangeni lokushisa lendawo eyisiliva.Ikhonjiswa kusetshenziswa iqoqo lendawo yokuqandisa echaziwe edingekayo kanye nomsebenzi wereferensi kanye nomsebenzi wokuchezuka we-interpolation yezinga lokushisa.
I-zoning yezinga lokushisa engenhla ihlukaniswe yaba amaningana futhi yanquma ukusebenza ngokujwayelekile ngaphakathi kwendawo yokushisa engaphansi ngezinhlobo ezahlukene zesakhiwo samathemometha.
Bona ama-thermometer anemininingwane etafuleni elingezansi:
| Uhlobo | Ukwahlukanisa | I-Suitable Temperature Zone | Ubude Bokusebenza(mm) | Izinga lokushisa |
| I-WZPB-1 | I | 0~419.527℃ | 470±10 | Maphakathi |
| I-WZPB-1 | I | -189.3442℃~419.527℃ | 470±10 | Igcwele |
| I-WZPB-2 | II | 0~419.527℃ | 470±10 | Maphakathi |
| I-WZPB-2 | II | -189.3442℃~419.527℃ | 470±10 | Igcwele |
| I-WZPB-7 | I | 0 ~ 660.323 ℃ | 510±10 | Maphakathi |
| I-WZPB-8 | II | 0 ~ 660.323 ℃ | 510±10 | Maphakathi |
Qaphela: I-Rtp yamathemometha angenhla ingu-25±1.0Ω.Ububanzi bangaphandle bamashubhu e-quartz ngu-φ7±0.6mm. Ifektri yethu iphinde ikhiqize ithemometha yeplatinamu enendawo yokushisa engu-83.8058K~660.323℃ njengethuluzi eliyisisekelo elisebenzayo.
II.Sebenzisa Ulwazi
1. Ngaphambi kokusebenzisa, okokuqala, hlola inombolo ye-thermometer ukuze ihambisane nesitifiketi sokuhlola.
2. Uma usebenzisa, ngokusho kwelogo yelug yetheminali yocingo lwethermometer, xhuma ucingo ngendlela efanele.I-lug① yocingo olubomvu ixhunywe kutheminali ephozithivu yamanje;ilugi③yentambo ephuzi, ukuya endaweni yamanje eyinegethivu;kanye nelug②yentambo emnyama, iye endaweni engase ibe khona ephozithivu;ilug④yentambo eluhlaza okotshani, kuya endaweni engaba khona eyinegethivu.
Okulandelayo uhlaka lwe-thermometer:
3. I-current kufanele ibe yi-1MA ngokusho kokulinganisa ingxenye yokushisa ye-thermometer.
4. Ukumatanisa idivayisi yokulinganisa kagesi yethemometha yokulinganisa izinga lokushisa, i-potentiometer yokumelana ephansi yebanga loku-1 kanye nokumelana nekhoyili evamile yebanga elingu-0.1 noma ibhuloho elinembile lokulinganisa lokushisa kanye nezinsiza kufanele kusetshenziswe.Isethi ephelele yedivayisi yokulinganisa kagesi kufanele iqinisekiswe ukuthi inozwela lokuhlukanisa ukuguqulwa kwe-Ohm eyodwa yezinkulungwane eziyishumi.
5. Ngesikhathi senqubo yokusebenzisa, ukulondolozwa nokuthutha, zama ukugwema ukudlidliza okunzima kwemishini ye-thermometer.
6. Lapho usebenzisa i-Standard Platinum Resistance Thermometer yebanga lokuqala ukuze uhlole izinga lokushisa lebanga lesibili I-Standard Platinum Resistance Thermometer, kufanele ilandele izinqubo zokuqinisekisa ezigunyazwe i-National Measurement Bureau.
7. Ukuhlolwa okuvamile kwe-thermometer kufanele kwenziwe ngokuqinile ngokuvumelana nezinqubo nemithetho yokuqinisekisa efanele.
