I-PT100 temperature sensor yinto yokulinganisa ubushushu, iiparameter zobushushu zento yokulinganisa ziguqulwa zibe ziiparameter zombane eziguquguqukayo. Xa imveliso kwisixhobo esikhethekileyo sokubonisa sedijithali, umboniso wexesha langempela wobushushu bento elinganisiweyo; ukufikelela kwinkqubo yolawulo lobushushu ehambelanayo kunye nokukhusela, ubushushu obungaqhelekanga buya kuyenza isebenze inkqubo yokukhusela, ibangele isenzo sokwaphula isekethe yombane, inqumle umbane wemoto, ukuze kuthintelwe iimpazamo zasekuhlaleni ngenxa yemoto ebangelwe yingozi embi. I-PT100 yindlela yokuguqula iiparameter zobushushu zibe ziiparameter zombane? Andiqondi ukuba ungaziva uyimfihlakalo kakhulu, emva kwengcaciso elandelayo usenokungadideki: I-PT100 RTD yenziwe kakhulu ngesinyithi seplatinum. Uzinzo lobushushu lwesinyithi seplatinum luphezulu kakhulu, ixabiso layo lokumelana kunye nobushushu kukho unxibelelwano oluqinileyo phakathi komntu nomnye.
Izinzwa zobushushu ze-PT100 zisetyenziswa kakhulu kwizixhobo zoshishino ukulinganisa nokulawula iiparameter zobushushu benkqubo. Izithumeli ezinezinzwa zihlala zineendawo ezimbini: isivamvo kunye nesiguquli sesignali. Izinzwa ikakhulu zii-thermocouples okanye ii-RTD; isiguquli sesignali ngokweeparameter zokulinganisa, ukucubungula isignali kunye neyunithi yokuguqula, ngokweemfuno zabathengi, ezinye izithumeli ziya kwandisa iyunithi yokubonisa ubushushu bexesha langempela, enamandla ikwanayo nomsebenzi we-fieldbus, olayishwe kwiziko lolawulo.
Imoto xa isetyenziswa kwi-PT100 xa ijongwa ubushushu bemoto kunye nokubeka esweni kunye nokukhuselwa kwendlela ethile: ukuqinisekisa ukuba kufuneka ijongwe umjikelo wobomi obupheleleyo bemoto, ngokwesiqhelo kwisigaba ngasinye sokujikajika kungcwatywe kwiiseti ezimbini zezinto zokulinganisa ubushushu, oko kukuthi, iseti yokulungiselela iseti; inxalenye yezinto zokulinganisa ubushushu inokutshintshwa kwindawo xa umonakalo ubangelwe, ngoko ke iseti yeebheringi inokuxhotyiswa ngesinye kuphela. Ke ngoko, umlinganiselo wobushushu weemoto ezinkulu ezinezigaba ezintathu ucwangciswa ngokubanzi ngokwemilinganiselo yobushushu enama-8: amanqaku amathathu okujikajika, amanqaku amabini ebheringi (iibheringi ezimbini zepivot point, inqaku ngalinye) kwi-intanethi, kwaye emva koko kubekwe amanqaku amathathu omlinganiselo wobushushu wokujikajika.
