I-Resistance Temperature Detector(RTD), eyaziwa nangokuthi ukumelana nokushisa, inzwa yokushisa esebenza ngesimiso sokulinganisa ukuthi 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 kanye 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.
