I-Resistance Temperature Detector(RTD), eyaziwa nangokuthi ukumelana nokushisa, inzwa yokushisa esebenza esimisweni sokulinganisa sokuthi ukumelana kukagesi kwe-sensor chip material kushintsha nezinga lokushisa.Lesi siciyenza i-RTD ibe inzwa ethembekile nenembile yokulinganisa izinga lokushisa ezinhlelweni ezihlukahlukene zezimboni.Uma ihlanganiswe ku-transmitter yezinga lokushisa, iba yithuluzi elinamandla lokuqapha nokulawula izinga lokushisa ezinkambisweni kanyeukudlala indima ebalulekile ezinhlelweni zokulawula inqubo yezimboni.
I-Pt100 ingenye yeplatinamu ethandwa kakhulu eyenziwe ukumelana nokushisa namuhla.Enye yezinzuzo zokusebenzisa izinzwa zokushisa ze-Pt100 ukunemba kwazo okuphezulu.Lezi zinzwa ziklanyelwe ukunikeza izilinganiso zokushisa ezinembile,ukubenza bafanelekele izindawo ezifunwa kakhulu zezimboni noma zaselabhorethri.Kungakhathaliseki ukuthi iqapha isitimu somoya, uketshezi, noma amagesi, izinzwa ze-Pt100 zingaletha ukufundwa okunembile, ziqinisekise ukuthi izinqubo zihamba kahle nangempumelelo.I-Pt100izinzwa nazo zaziwa ngokuqina kwazo.Zenzelwe ukumelana nezimo zemvelo ezinzima, zizenze zilungele ukusetshenziswa ezindaweni zezimboni lapho ukuguquka kwezinga lokushisa nokuchayeka kumakhemikhali noma umswakama.evamile.Lokhu kwakhiwa okuqinile kuqinisekisa ukuthi izinzwa ze-Pt100 zingaqhubeka nokuhlinzeka ngezilinganiso ezinembile ngisho nasezimeni zokusebenza eziyinselele.
Aisidluliseli sokushisaiyakwazi ukuguqula ukumelana kwenzwa ye-Pt100 ibe isignali ejwayelekile ye-4-20mA, engadluliselwa ekulawuleni izinhlelo zokuqapha nokulawula inqubo.Lokhu kusebenza kwenza izidlulisi zokushisa ze-Pt100 zibe izingxenye ezibalulekile ezinhlelweni ezishintshayo nezilawulayo zezimboni, okuvumela ukuhlanganiswa okungenamthungo nemishini nezinqubo ezikhona.Uma kucutshungulwa ukusetshenziswa kwesidlulisi sezinga lokushisa le-RTD, kufanele kucatshangelwe imingcele eminingana ebalulekile.Lokhu kufaka phakathi ukuxhumeka kwenqubo, ukujula kokufaka, kanye nobubanzi benduku, okungaba nomthelela omkhulu ekunembeni nasekuthembekeni kwesilinganiso sokushisa.Ngaphezu kwalokho, umkhiqizo uyatholakala futhi ku-explosion-proof kanye nezinketho ze-thermowell, ukuqinisekisa ukuphepha nokuqina ezindaweni zezimboni eziyinselele..Izinketho zesignali zokukhipha zihlanganisa i-4-20mA, RS-485, nephrothokholi ye-HART, okwenza ama-intruments ahambisane nokulawulwa kwezimboni ezahlukene. izinhlelo.
Thina, i-Shanghai Wangyuan Instruments of Measurement Co., Ltd. iyibhizinisi elihamba phambili laseShayina lobuchwepheshe obuphezulu elisebenza ngobuchwepheshe bokulawula inqubo yezimboni kanye nemikhiqizo amashumi eminyaka futhi sinikela ngekhwalithi ephezulu eyenziwe ngokwezifiso.ama-transmitter athembekilenge-Pt100 sensor element yokwanelisa izidingo ezithile zazo zonke iziza ze-indstuial.
