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 njengezinga lapho kuhlolwa izinhlobonhlobo zamathemometha ajwayelekile namathemometha anembe 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:

Qaphela: I-Rtp yamathemometha angenhla ngama-25±1.0Ω.Ububanzi bangaphandle bamashubhu e-quartz bungu-φ7±0.6mm.imboni yethu futhi yenza i-thermometer 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;isikhwama③ocingweni oluphuzi, kuya endaweni yamanje eyinegethivu;kanye nesigubhu②yocingo olumnyama, kuya endaweni engaba khona ephozithivu;isikhwama④yocingo oluluhlaza, kuya endaweni engase ibe negethivu engaba khona.

Okulandelayo uhlaka lwe-thermometer:

3. I-current kufanele ibe yi-1MA ngokukalwa kwengxenye 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. Phakathi nenqubo yokusebenzisa, ukulondolozwa nokuthutha, zama ukugwema ukudlidliza okunzima kwemishini ye-thermometer.

6. Lapho usebenzisa i-Standard Platinum Resistance Thermometer yebanga lokuqala ukuhlola 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.
