Ukunemba okuphezulu kwe-PT100 inzwa ye-platinamu yokumelana nezinga lokushisa lochungechunge lwe-T

Uchungechunge lwe-T sensor ye-temperature lufanele ukukalwa kwezinga lokushisa elingaphezulu kwemishini, izinga lokushisa loketshezi kanye nezinga lokushisa legesi.Kuyisibopho somsebenzisi ukuqinisekisa ukuthi okokusebenza kuzifanele izimo zokusebenza zohlelo lokusebenza.

Ukulinganisa izinga lokushisa kwenziwa ngokusekelwe kumphumela oshisayo wokumelana.Kusho Ukumelana ne-resistor kushintsha ngokushintsha kwezinga lokushisa.Inzwa yokushisa ye-PT100 ingumtshina wokushisa wokumelana ne-platinum (Pt).Ubudlelwano phakathi kokumelana nokushintsha kwezinga lokushisa bumi kanje: R=R0(1+aT) lapho a=0.00392, u-R0 engu-100 (inani lokumelana kokuthi 0℃), kanye no-T izinga lokushisa eliku-Celsius.Ngakho-ke, umtshina wokushisa we-Resistance owenziwe nge-platinum waziwa nangokuthi i-PT100.
