PR1231/PR1232 Standard Platinum-10% Rhodium/Platium Thermocouple

Part1 Uhlolojikelele

Ibanga lokuqala nelesibili i-platinamu-iridium 10-platinum thermocouples enezinga eliphezulu lokunemba okuhle ngokomzimba namakhemikhali, ukumelana okuhle kwe-oxidation emazingeni okushisa aphezulu, ukuzinza okuhle kanye nokuphindaphinda kwamandla we-thermoelectromotive.Ngakho-ke, isetshenziswa njengethuluzi lokulinganisa elijwayelekile ku-(419.527~1084.62) °C , iphinde isetshenziselwe ukudlulisa ubukhulu bezinga lokushisa kanye nesilinganiso sokushisa esinembayo ebangeni lokushisa.

Ingxenye3 Imiyalo yohlelo lokusebenza

ama-thermocouples ajwayelekile e-platinum-iridium 10-platinum kumele ahambisane nethebula lesistimu yokulethwa kwezidingo kazwelonke, kumele kusetshenziswe izinqubo zokuqinisekisa zikazwelonke.Ibanga lokuqala elijwayelekile le-platinum-iridium 10-platinum thermocouples lingasetshenziswa ukukala ibanga lesibili,Ⅰ grade,Ⅱ grade platinum-iridium 10-platinum thermocouples kanye Ⅰ grade base base metal thermocouples;I-platinamu-iridium ye-10-platinum thermocouples yebanga lesibili ingasetshenziswa kuphela ukukala Ⅱ isisekelo sensimbi thermocouples

Ikhodi kazwelonke yokuqinisekisa	Igama lokuqinisekisa likazwelonke
JJG75-1995	ukucaciswa kokulinganisa kwe-platinum-iridium 10-platinum thermocouples okujwayelekile
JJG141-2013	Ukusebenza okubalulekile kwe-metal thermocouples calibration specification
JJF1637-2017	ukucaciswa kwesisekelo sensimbi ye-thermocouple yokulinganisa

Ingxenye4 Ukugcinwa Nokugcinwa

1. Isikhathi esijwayelekile sokulinganiswa kwe-thermocouple unyaka ongu-1, futhi minyaka yonke i-thermocouple ejwayelekile kufanele ilinganiswe ngomnyango we-metrology.

2. Ukulinganiswa kokuqondisa okudingekayo kufanele kwenziwe ngokuvumelana nokusetshenziswa.

3. Indawo yokusebenza ye-thermocouple ejwayelekile kufanele ihlanzeke ukugwema ukungcoliswa kwe-thermocouple ejwayelekile.

4. I-thermocouple ejwayelekile kufanele ibekwe esimweni esingangcolisi futhi ivikelwe ekucindezelekeni kwemishini.

Ingxenye5 Izinyathelo zokuqapha lapho usebenzisa

1. Ishubhu yokufaka ugesi ayikwazi ukusetshenziswa ekushiseni okuphezulu.Ishubhu yokuqala yokufaka i-insulation isetshenziswa ngemuva kokuhlanza okuqinile kanye nokugazinga okuphezulu kokushisa.

2. Ishubhu yokufaka ishubhu ayinaki okuhle nokubi, okuzobangela ukuba isigxobo seplatinamu sonakaliswe futhi inani lamandla kagesi we-thermoelectric lehle.

3. Ngokungahleliwe ishubhu elivamile lokufakwa kwe-thermocouple elinocingo olushibhile lizongcolisa i-thermocouple evamile, futhi ishubhu lensimbi elivikelayo kufanele lisetshenziswe ukuze kuqinisekiswe isisekelo se-thermocouple yensimbi.

4. I-thermocouple evamile ayikwazi ukufakwa ngokuzumayo esithandweni sokulawula izinga lokushisa, noma ikhishwe esithandweni sokushisa esilawula ukushisa.Ukushisa okungazelelwe nokubanda kuzothinta ukusebenza kukagesi we-thermoelectric

5.Ngaphansi kwezimo ezijwayelekile, isithando somlilo sokuqinisekisa se-thermocouple yensimbi eyigugu kanye nesisekelo se-thermocouple yensimbi kufanele kuhlukaniswe ngokuqinile;uma kungenakwenzeka, ishubhu le-ceramic elihlanzekile noma ishubhu le-corundum(ububanzi obungaba ngu-15mm) kufanele lifakwe kushubhu yesithando somlilo ukuze kuvikelwe ama-Thermocouple ensimbi ayigugu nama-thermocouples ajwayelekile ekungcoleni kwesisekelo sensimbi ye-thermocouple.
