Kev xaiv tsis raug ntawm RTD (Resistance Temperature Detector) yuav ua rau muaj kev cuam tshuam qhov ntsuas kub ntsuas qhov tseeb, vim tias muaj qhov sib txawv ntawm 2-xaim, 3-xaim thiab 4-xaim RTD teeb tsa.
2-Wire RTD
Featuring qhov kev tsim kho yooj yim tshaj plaws nrog tsuas yog ob txoj kev sib txuas, 2-xaim RTD los nrog tus nqi qis tshaj. Txawm li cas los xij, lub hauv paus tsis kam ntawm cov kab txuas txuas ntxiv yuav suav nrog hauv qhov ntsuas ntsuas qhov tseem ceeb thiab ua rau kev nyeem ntawv drift. Nws tsuas yog pom zoo rau kev xaim luv luv thiab cov ntawv thov uas tsis muaj qhov tseeb.
3-Wire RTD (Nrov tshaj plaws rau kev siv)
Raws li kev lag luam- kev xaiv tus qauv, cov hlau lead ntxiv tshem tawm feem ntau ntsuas qhov yuam kev tshwm sim los ntawm cov hlau lead tsis kam. Nws muab kev sib npaug ntawm qhov tseeb thiab kev ua tau zoo ntawm tus nqi. Dav dav ntsia ntawm boilers, txheej txheem pipelines thiab lwm yam kev lag luam khoom, nws siab tshaj plaws zoo kis tau tus mob nyob deb li cas ntawm 50 meters mus rau 100 meters.
4-Wire RTD (High Precision Qib)
Kev khav theeb saum toj kawg nkaus -tier ntsuas qhov tseeb, 4-wire RTD txais ib qho kev tsim hluav taws xob tshwj xeeb: ob lub xov hlau muab cov khoom siv hluav taws xob tsis tu ncua thaum lwm qhov ob ntawm nws tus kheej ntes cov teeb liab voltage. Qhov kev tsim qauv no tau txiav txim siab tawm tsam kev cuam tshuam, txwv tag nrho kev ntsuas qhov yuam kev hauv ± 0.2%. Nws yog qhov kev xaiv zoo tshaj plaws rau kev kuaj xyuas qhov tseeb, cov khoom siv hluav taws xob semiconductor thiab lwm yam kev ntsuas qhov ntsuas kub qhov tseeb.
