Kungani izinzwa eziningi zokushisa zisebenzisa i-Pt1000 ukukala ukushisa? Yimuphi umehluko phakathi kwe-Pt1000, i-Pt500 kanye ne-Pt100?

I-Pt1000 iyi-resistor ye-platinum thermal, futhi inani layo lokumelana lizoshintsha ngokushintsha kwezinga lokushisa. Inombolo engu-1000 ngemuva kwe-“Pt” ikhombisa ukuthi inani layo lokumelana lingu-1000 ohms ku-0°C, kanti inani layo lokumelana licishe libe ngu-1758.56 ohms ku-200°C. Inani lokumelana le-PT1000 liyanda ngokufanayo njengoba izinga lokushisa likhuphuka. I-Pt100 nayo iyi-resistor ye-platinum thermal. Inombolo engu-100 ngemuva kwe-“Pt” ikhombisa ukuthi inani layo lokumelana lingama-100 ohms ku-0°C, kanti inani layo lokumelana licishe libe ngu-175.86 ohms ku-200°C. I-Pt500 nayo iyi-resistor ye-platinum thermal. Inombolo engu-500 ngemuva kwe-“Pt” ikhombisa ukuthi inani layo lokumelana lingama-500 ohms ku-0°C, kanti inani layo lokumelana licishe libe ngu-879.30 ohms ku-200°C.

Namuhla, i-Pt1000 isetshenziswa kakhulu ekulinganisweni kwezinga lokushisa kumamitha okushisa noma ama-calorimeter. Okokuqala, inombolo yokuphothula ye-Pt1000 inkulu, okuholela ekunembeni okuphezulu. Okwesibili, i-input impedance ye-Pt1000 iphakeme, futhi i-voltage yokuvuselela ingakhushulwa, ngaleyo ndlela kuthuthukiswe ukuzwela. Okwesithathu, i-PT1000 ifanelekela ukukala izinguquko zokushisa ezincane (isizathu ukuthi lapho izinga lokushisa lishintsha ngedigri elilodwa, ushintsho lwenani lokumelana lukhulu kakhulu, futhi isekethe elandelayo ingalubona kalula). Ngokusetshenziswa, i-Pt1000 nayo ilula kakhulu. Ezisetshenzisweni zezimboni, ngokuvamile, izimpawu zokumelana ze-Pt100 ne-Pt500 ziguqulwa zibe izimpawu zamanje ze-4-20mA, bese izimpawu ziyacutshungulwa. Kodwa-ke, i-Pt1000 ilinganisa ngqo isignali yokumelana.
