Inzwa yokushisa ye-PT100 iyisici sokulinganisa izinga lokushisa, amapharamitha okushisa ento yokulinganisa aguqulwa abe amapharamitha kagesi aguquguqukayo. Lapho okukhiphayo kuthuluzi lokubonisa ledijithali elikhethekile, ukuboniswa kwesikhathi sangempela kokushisa kwento elinganisiwe; ukufinyelela ohlelweni lokulawula izinga lokushisa oluhambisanayo, izinga lokushisa elingavamile lizosebenza uhlelo lokuvikela, okubangela isenzo sokwephula isifunda sokuhambisa ugesi, kunqume ukunikezwa kwamandla emoto, ukuze kugwenywe amaphutha endawo ngenxa yemoto ebangelwe yingozi embi. I-PT100 iyindlela yokuguqula amapharamitha okushisa abe amapharamitha kagesi? Angiqondi ukuthi ungazizwa uyimfihlakalo kakhulu, ngemuva kwencazelo elandelayo ungase ungadideki kakhulu: I-PT100 RTD yakhiwe kakhulu ngensimbi yeplatinum. Ukuzinza kokushisa kwensimbi yeplatinum kuphezulu kakhulu, inani layo lokumelana kanye nokushisa kukhona ukuxhumana okuqinile phakathi komuntu nomuntu.
Izinzwa zokushisa ze-PT100 zisetshenziswa kabanzi emishinini yezimboni ukuze kulinganiswe futhi kulawulwe amapharamitha okushisa kwenqubo. Ama-transmitter anama-sensor ngokuvamile aqukethe izingxenye ezimbili: i-sensor kanye ne-converter yesignali. Ama-sensor ikakhulukazi ama-thermocouple noma ama-RTD; i-converter yesignali ngamapharamitha okulinganisa, iyunithi yokucubungula isignali kanye nokuguqulwa, ngokwesidingo samakhasimende, amanye ama-transmitter azokwandisa iyunithi yokubonisa izinga lokushisa ngesikhathi sangempela, enamandla futhi inomsebenzi we-fieldbus, olayishwe esikhungweni sokulawula.
Injini ekusetshenzisweni kwe-PT100 ekuqapheni nasekuvikeleni izinga lokushisa kwenjini kanye nokuqapha izinga lokushisa lenjini kanye nokuvikela indlela ethile: ukuqinisekisa ukuthi ukuqapha umjikelezo wokuphila wenjini ogcwele udinga, ngokuvamile esigabeni ngasinye sokugoba kungcwatshwe amasethi amabili ezingxenye zokulinganisa izinga lokushisa, okungukuthi, isethi yokulungiselela isethi; ingxenye yokuthwala yezingxenye zokulinganisa izinga lokushisa ingashintshwa endaweni lapho umonakalo ubangelwa, ngakho-ke isethi yamabhereyi ingafakelwa eyodwa kuphela. Ngakho-ke, ukulinganisa izinga lokushisa kwama-motor amakhulu anezigaba ezintathu ngokuvamile kuhlelwe ngokwesilinganiso sokushisa samaphuzu angu-8: amaphuzu amathathu okugoba, amaphuzu amabili okugoba (amabhereyi amabili e-pivot point, iphuzu ngalinye) ku-inthanethi, bese kumiswa amaphuzu amathathu okulinganisa izinga lokushisa lokugoba.
