Inzwa yokushisa ye-PT100 iyisici sokulinganisa izinga lokushisa, imingcele yokushisa yento yokulinganisa iguqulwa ibe imingcele kagesi eguquguqukayo.Lapho okukhiphayo kuthuluzi lokubonisa elikhethekile ledijithali, isibonisi sesikhathi sangempela sezinga lokushisa elilinganisiwe;ukufinyelela kusistimu yokulawula izinga lokushisa ehambisanayo kanye nesistimu yokuvikela, izinga lokushisa elingavamile lizokwenza kusebenze uhlelo lokuvikela, liqalise isenzo se-breaker circuit breaker, linqamule ukunikezwa kwamandla emoto, ukugwema amaphutha wendawo ngenxa yemoto ebangelwe ingozi embi.I-PT100 indlela yokuguqula amapharamitha okushisa abe yimingcele kagesi?Awuqondi ungase uzizwe ungaqondakali, ngemva kwencazelo elandelayo ungase ungakhungatheki: I-PT100 RTD ikakhulukazi yakhiwe nge-platinum metal.Ukuzinza kwe-Platinum metal ezishisayo kuphezulu kakhulu, inani layo lokumelana nokushisa kukhona ukuxhumana okuqinile phakathi komunye nomunye.
Izinzwa zokushisa ze-PT100 zisetshenziswa kabanzi kumishini yezimboni yokulinganisa nokulawula imingcele yokushisa kwenqubo.Ama-transmitter anezinzwa ngokuvamile anezingxenye ezimbili: inzwa nesiguquli sesignali.Izinzwa ngokuyinhloko zingama-thermocouples noma ama-RTD;isiguquli sesignali ngamapharamitha wokulinganisa, ukucubungula isignali kanye neyunithi yokuguqulwa, ngokusho kwesidingo samakhasimende, abanye abathumeli bazokwandisa iyunithi yokubonisa izinga lokushisa langempela-isikhathi, enamandla futhi inomsebenzi we-fieldbus, elayishwe esikhungweni sokulawula.
I-Motor ekusetshenzisweni kwe-PT100 ku-motor winding kanye nokuqapha izinga lokushisa kanye nokuvikelwa kwendlela ethize: ukuze kuqinisekiswe ukuthi ukuqapha umjikelezo wempilo egcwele yemoto, ngokuvamile esigabeni ngasinye sokuvala ukuvala kungcwatshwa amasethi amabili ezingxenye zokulinganisa izinga lokushisa, okungukuthi, isethi yokulungiselela isethi;ukuthwala ingxenye yezingxenye zokulinganisa izinga lokushisa kungashintshwa endaweni lapho umonakalo udalekile, ngakho isethi yamabheringi ingahlonywa eyodwa kuphela.Ngakho-ke, ukukalwa kwezinga lokushisa kwamamotho amakhulu ezigaba ezintathu ngokuvamile kulungiselelwa ngokwesilinganiso sokushisa samaphuzu angu-8: amaphuzu amathathu okujikajika, amaphuzu amabili okuthwala (amabhorethi amaphoyinti amabili e-pivot, iphuzu ngalinye) ku-inthanethi, bese kuba okubekwe okuthathu. amaphuzu wesilinganiso sokushisa esimazombezombe.
