Pt100 RTD mu Ntchito Zamakampani

Chowunikira Kutentha Chotsutsa (RTD), yomwe imadziwikanso kuti kukana kutentha, ndi sensa yoyezera kutentha yomwe imagwira ntchito motsatira mfundo yoyezera kuti kukana kwa magetsi kwa zinthu za sensa kumasintha ndi kutentha. Mbali iyi ndi yamagetsi.imapangitsa RTD kukhala sensa yodalirika komanso yolondola yoyezera kutentha m'mafakitale osiyanasiyana. Ikaphatikizidwa mu chotumizira kutentha, imakhala chida champhamvu chowunikira ndikuwongolera kutentha m'machitidwe ndiamagwira ntchito yofunika kwambiri mu machitidwe owongolera njira zamafakitale.

Pt100 ndi imodzi mwa zipangizo zodziwika bwino zotetezera kutentha zopangidwa ndi platinamu masiku ano. Chimodzi mwa ubwino wogwiritsa ntchito masensa otentha a Pt100 ndi kulondola kwawo kwakukulu. Masensawa adapangidwa kuti apereke miyeso yeniyeni ya kutentha,kuzipangitsa kukhala zoyenera m'malo ovuta a mafakitale kapena a labotale. Kaya ndi kuyang'anira nthunzi ya mpweya, zakumwa, kapena mpweya, masensa a Pt100 amatha kupereka mawerengedwe olondola, kuonetsetsa kuti njira zikuyenda bwino komanso moyenera. Pt100Masensa amadziwikanso chifukwa cha kulimba kwawo. Amapangidwira kuti azitha kupirira nyengo zovuta zachilengedwe, zomwe zimapangitsa kuti akhale abwino kwambiri kugwiritsidwa ntchito m'mafakitale komwe kusinthasintha kwa kutentha ndi kukhudzana ndi mankhwala kapena chinyezi kumakhalapo.wamba. Kapangidwe kolimba kameneka kamatsimikizira kuti masensa a Pt100 amatha kupitiliza kupereka miyeso yolondola ngakhale m'mikhalidwe yovuta yogwirira ntchito.

Achotumizira kutenthaimatha kusintha kukana kwa sensa ya Pt100 kukhala chizindikiro chokhazikika cha 4-20mA, chomwe chimatha kutumizidwa ku makina owongolera kuti aziyang'anira ndikuwongolera machitidwe. Kugwira ntchito kumeneku kumapangitsa kuti ma transmitter a kutentha a Pt100 akhale ofunikira kwambiri mu makina owongolera mafakitale ndi machitidwe owongolera, zomwe zimathandiza kuti pakhale kuphatikizana kosasunthika ndi zida ndi machitidwe omwe alipo. Poganizira kugwiritsa ntchito chosinthira kutentha cha RTD, magawo angapo ofunikira ayenera kuganiziridwa. Izi zikuphatikizapo kulumikizana kwa njira, kuya kwa kulowetsa, ndi m'mimba mwake wa ndodo, zomwe zingakhudze kwambiri kulondola ndi kudalirika kwa muyeso wa kutentha. Kuphatikiza apo, mankhwalawa amapezekanso m'njira zotetezeka kuphulika komanso thermowell, kuonetsetsa kuti chitetezo ndi kulimba m'malo ovuta amakampani.. Zosankha za chizindikiro chotulutsa zimaphatikizapo 4-20mA, RS-485, ndi protocol ya HART, zomwe zimapangitsa kuti zidazo zigwirizane ndi machitidwe osiyanasiyana owongolera mafakitale.

Ife, Shanghai Wangyuan Instruments of Measurement Co., Ltd. ndi kampani yotsogola kwambiri yaku China yomwe imadziwika bwino ndi ukadaulo wowongolera njira zamafakitale ndi zinthu kwa zaka zambiri ndipo imapereka zinthu zapamwamba zomwe zingasinthidwe kukhala zokhazikika.zotumizira kutentha kwa temperatruendi chipangizo cha Pt100 chomwe chimapereka zofunikira zinazake pa malo aliwonse a kampani.
