Vim li cas PRTs suav hais tias yog qhov ntsuas kub ruaj khov tshaj plaws?

Stability txhais lub sensor lub peev xwm los tswj kom raug calibration nyob rau hauv lub sij hawm tsis muaj drift los yog degradation, thiab PRTs yog universally lees paub tias yog qhov ruaj khov kub sensors muaj. Qhov kev ruaj ntseg tshwj xeeb no yog los ntawm cov khoom muaj txiaj ntsig ntawm platinum thiab rugged inorganic kev tsim kho ntawm PRT tsim. Platinum yog ib qho tshuaj lom neeg tsis muaj zog hlau uas tsis oxidize, corrode, los yog hloov cov qauv nyob rau lub sij hawm, khaws cia ib tug tsis tu ncua tsis kam-kub kev sib raug zoo. Tsis zoo li lwm yam ntaub ntawv uas degrade los yog drift, platinum tseem ruaj khov rau xyoo txawm nyob rau hauv ib puag ncig hnyav. PRTs siv magnesium oxide rwb thaiv tsev thiab hlau sheaths uas tsis tawg, outgas, los yog kis tau tus kab mob. Qhov kev tsim kho no tshem tawm drift los ntawm cov khoom aging lossis ib puag ncig kev cuam tshuam. PRTs nthuav tawm tsis tshua muaj hysteresis thiab rov ua tau zoo txawm tias tom qab siv ntev. Lawv tuav calibration ntev tshaj li cov thermistor, thermocouples, los yog lwm yam sensor, txo cov nqi kho thiab calibration. Kev ruaj ntseg yog qhov tseem ceeb hauv kev tswj hwm kev lag luam xws li tshuaj, khoom noj khoom haus, thiab aerospace, qhov twg kev ntsuas tsis sib haum ua rau muaj kev phom sij thiab kev ua raws cai. Txawm hais tias nyob rau hauv lub chaw soj nstuam, cov chaw tsim khoom lag luam, lossis cov txheej txheem kev nyab xeeb tseem ceeb, PRTs muab kev ruaj ntseg ruaj khov uas ua kom muaj kev ntseeg siab ntev ntev.
