I-PT1000 Kala Izinsimbi I-Platinum Resistance Temperature Sensor
Izinzwa ze-Platinum Resistance Temperature
Ngokufanayo nama-thermistors, izinzwa ze-platinamu ukumelana nezinga lokushisa (ama-RTD) ziyizinqamuli ezizwela ukushisa ezenziwe nge-platinum.
Izinzwa ze-Platinum ukumelana nezinga lokushisa zisebenzisa izici ze-platinum yensimbi ukukala izinga lokushisa ngokushintsha inani layo lokumelana lapho izinga lokushisa lishintsha, futhi ithuluzi lokubonisa lizobonisa inani lokushisa elihambisana nenani lokumelana lokumelana neplatinamu. Uma kune-gradient yezinga lokushisa endaweni elinganisiwe, izinga lokushisa elilinganisiwe liyizinga lokushisa elimaphakathi lesendlalelo esimaphakathi ngaphakathi kobubanzi besici senzwa.
Ukumelana ne-Platinum kungahlukaniswa ngezinga lokushisa eliphansi kakhulu, izinga lokushisa eliphansi, izinga lokushisa eliphakathi nendawo kanye namazinga okushisa aphezulu ngokuya ngebanga lokushisa lokulinganisa, lapho
izinga lokushisa eliphansi kakhulu: -196 ° C kuya +150 ° C,
izinga lokushisa eliphansi: -50 ° C kuya +400 ° C,
izinga lokushisa eliphakathi nendawo: -70 ° C kuya +500 ° C, futhi
izinga lokushisa eliphezulu lingasetshenziselwa ukulinganisa izinga lokushisa elifika ku-850 ° C.

Izici ze-Platinum Resistance Temperature Sensor
I-Thin-film ye-RTD yokumelana ne-platinamu izici zibonakala ngokunemba okuphezulu, ukuzinza okuphezulu, nokuphendula okusheshayo, futhi zivame ukusetshenziswa emikhakheni ye-instrumentation, imishini yezokwelapha, nemishini yamakhemikhali. Izinqamuleli zePlatinum zinobudlelwano bomugqa phakathi kwevelu yokumelana nezinga lokushisa.
Izinzwa zokumelana nePlatinum zinokuzinza okuhle kwesikhathi eside, ezinedatha yokuhlola evamile yamahora angu-300 ku-400°C kanye nezinga lokushisa eliphezulu lokukhukhuleka elingu-0.02°C ku-0°C.

Inani eliphakeme lokumelana: inani lokumelana le-pt100 ukumelana ne-platinum liyi-100 ohms ku-0, futhi inani lokumelana le-pt1000 ukumelana ne-platinum liyi-1000 ohms. Inani lokumelana lokumelana neplatinamu lehla kancane kancane ngokwanda kwezinga lokushisa, ngakho lifaneleka njengengxenye eyinhloko yethuluzi lokushisa.
Ukuzwela okuphezulu: Ingakwazi ukuphendula ngokushesha ezinguqukweni zezinga lokushisa elizungezile, futhi isikhathi sayo esihambisanayo singu-0.15s kuphela emanzini ageleza kancane.
Usayizi omncane: kuncane kakhulu, ngokuhleleka kwamamilimitha, ngakho-ke kufanelekile ngokukhethekile ukufakwa ezindaweni ezinendawo elinganiselwe, njengezinsimbi zokushisa. Ithuluzi lokushisa ngokwalo lincane ngosayizi, futhi ifilimu encane ye-platinum resistor ifaneleka kakhulu.
Ukuzinza okuhle: Izibalo ziphinde zibonisa ukuthi i-platinum resistors isebenza ngokuqhubekayo ku-600 amahora angaphezu kuka-1000, futhi ukuguqulwa kokumelana kungaphansi kuka-0.02%.
Izindleko eziphansi: Izindleko ziphansi ngaphansi kwesimo sokukhiqiza okuzenzakalelayo okukhulu, okungaphansi ngo-50% -60% kunezinqamuleli ze-wirewound ezifanayo.
