I-PT1000 yokulinganisa i-Instruments ye-Platinum Resistance Temperature Sensor
Platinum Resistance Temperature Sensors
Ngokufanayo ne-thermistors, i-platinam yokumelana nobushushu boluvo (i-RTDs) zi-resistors ezithintekayo kubushushu ezenziwe ngeplatinam.
Abenzi bobushushu bePlatinam bokumelana nokusetyenziswa kweempawu zentsimbi yeplatinam ukulinganisa ubushushu ngokuguqula ixabiso layo lokumelana xa ubushushu butshintsha, kwaye isixhobo sokubonisa siya kubonisa ixabiso lobushushu elihambelana nexabiso lokumelana neplatinam. Xa kukho iqondo lobushushu kumlinganiselo ophakathi, ubushushu obulinganisiweyo bubushushu obuqhelekileyo bomgangatho ophakathi ngaphakathi koluhlu lwento yokuva.
Ukumelana nePlatinam kunokohlulwa kubushushu obuphantsi kakhulu, ubushushu obuphantsi, ubushushu obuphakathi kunye nomgangatho wobushushu obuphezulu ngokoluhlu lobushushu bomlinganiselo, apho
Uluhlu lobushushu obuphantsi kakhulu: -196 ° C ukuya +150 ° C,
uluhlu lobushushu obuphantsi: -50 ° C ukuya +400 ° C,
uluhlu lobushushu eliphakathi: -70 ° C ukuya +500 ° C, kunye
ubushushu obuphezulu bunokusetyenziselwa umlinganiselo wobushushu ukuya kuma 850 ° C.

Iimpawu zePlatinum Resistance Temperature Sensor
I-Thin-film ye-RTD yokumelana ne-platinam izinto ezibonakaliswe ngokuchaneka okuphezulu, ukuzinza okuphezulu, kunye nokuphendula ngokukhawuleza, kwaye zihlala zisetyenziselwa kwiinkalo zezixhobo, izixhobo zonyango kunye nezixhobo zekhemikhali. Izichasi zePlatinam zinobudlelwane bomgca phakathi kwexabiso lokumelana kunye nobushushu.
Izixhobo zokumelana nePlatinam zinozinzo oluhle lwexesha elide, kunye nedatha yovavanyo eqhelekileyo yeeyure ezingama-300 kwi-400 ° C kunye nobushushu obuphezulu be-0.02 ° C kwi-0 ° C.
IAinzuzosye PT100, PT200, PT1000 iPlatinam yobushushu boluvo lweIzixhobo zokulinganisa
Ixabiso eliphezulu lokuxhathisa: ixabiso lokumelana ne-pt100 ukumelana ne-platinum yi-100 ohms kwi-0, kunye nexabiso lokumelana ne-pt1000 yokumelana ne-platinum yi-1000 ohms. Ixabiso lokumelana nokumelana neplatinam liyancipha ngokuthe ngcembe ngokunyuka kweqondo lokushisa, ngoko lifanelekile njengenxalenye ephambili yesixhobo sokushisa.
Uvakalelo oluphezulu: Iyakwazi ukuphendula ngokukhawuleza utshintsho kwiqondo lokushisa eliphantsi, kwaye ixesha layo elihambelanayo liyi-0.15 kuphela emanzini ahamba kancinci.
Ubungakanani obuncinci: incinci kakhulu, ngokomyalelo weemilimitha, ngoko ifaneleke ngokukodwa ukufakwa kwiindawo ezinendawo encinci, njengezixhobo zokushisa. Isixhobo sokushisa ngokwaso sincinci ngobukhulu, kwaye i-platinum resistor ifilimu encinci ifanelekile kakhulu.
Uzinzo oluhle: Izibalo zibonisa ukuba i-platinum resistors isebenza ngokuqhubekayo kwi-600 ngaphezu kweeyure ze-1000, kwaye ukuguqulwa kokumelana kungaphantsi kwe-0.02%.
Ixabiso eliphantsi: Ixabiso liphantsi phantsi kwemeko yokuvelisa ubuninzi obuzenzekelayo, obuyi-50% -60% ephantsi kunezixhasi ezifanayo ze-wirewound.
