4 Wire PT100 RTD Izinzwa Zokushisa
4 Wire PT100 RTD Izinzwa Zokushisa
Ukuxhumana kwemikhondo emibili ekugcineni kwempande ye-platinum resistor kwaziwa ngokuthi uhlelo lwezintambo ezine, lapho okubili okuholayo kuhlinzeka ngokuqhubekayo okwamanje ku-resistor platinum! , eguqula u-R abe isignali kagesi engu-U, bese iholela u-U ensimbini yesibili ngokusebenzisa eminye imikhondo emibili.
Ngenxa yokuthi isignali ye-voltage iholwa ngokuqondile kusukela ekuqaleni kokumelana ne-platinum, kungabonakala ukuthi le ndlela ingakwazi ukuqeda ngokuphelele umphumela wokumelana nokuhola, futhi isetshenziselwa ikakhulukazi ukutholwa kokushisa okuphezulu.
Uyini umehluko phakathi kwesistimu yezintambo ezimbili, izintambo ezintathu kanye nezintambo ezine?
Izindlela eziningana zokuxhuma zinezici zazo, ukusetshenziswa kwesistimu yezintambo ezimbili kulula kakhulu, kodwa ukunemba kokulinganisa nakho kuphansi. Uhlelo lwezintambo ezintathu lungasusa kangcono umthelela wokumelana nomthofu futhi lusetshenziswa kabanzi embonini. Uhlelo lwezintambo ezine lungasusa ngokuphelele umthelela wokumelana nomthofu, osetshenziswa kakhulu ekulinganisweni kokunemba okuphezulu.
