PT100 RTD mu Industrial Applications

Resistance Temperature Detector (RTD), komanso kudziwa ngati kukana matenthedwe, ndi kachipangizo kutentha ntchito pa mfundo muyeso kuti kukana magetsi a kachipangizo Chip zakuthupi kusintha ndi kutentha. Mbali imeneyiimapangitsa RTD kukhala sensor yodalirika komanso yolondola yoyezera kutentha m'mafakitale osiyanasiyana. Ikaphatikizidwa mu chotengera kutentha, imakhala chida champhamvu chowunikira ndikuwongolera kutentha munjira ndiimagwira ntchito yofunika kwambiri pakuwongolera njira zama mafakitale.

Pt100 ndi imodzi mwazinthu zodziwika bwino za platinamu zomwe zimapangidwa masiku ano. Ubwino umodzi wogwiritsa ntchito masensa a kutentha kwa Pt100 ndi kulondola kwawo kwakukulu. Masensa awa adapangidwa kuti azipereka miyeso yolondola ya kutentha,kuwapanga kukhala oyenera malo ofunikira a mafakitale kapena ma labotale. Kaya imayang'anira nthunzi ya mpweya, zakumwa, kapena mpweya, masensa a Pt100 amatha kuwerengera molondola, kuwonetsetsa kuti njira zikuyenda bwino komanso moyenera. pt100masensa amadziwikanso kuti ndi olimba. Amapangidwa kuti athe kupirira zovuta zachilengedwe, kuwapangitsa kukhala abwino kugwiritsidwa ntchito m'mafakitale komwe kusinthasintha kwa kutentha ndi kukhudzana ndi mankhwala kapena chinyezi.wamba. Kumanga kolimba kumeneku kumatsimikizira kuti masensa a Pt100 apitilize kupereka miyeso yolondola ngakhale pamavuto.

Achopatsira kutenthaimatha kusintha kukana kwa sensor ya Pt100 kukhala chizindikiro chokhazikika cha 4-20mA, chomwe chimatha kuperekedwa kumakina owongolera owunikira ndikuwongolera njira. Kugwira ntchito kumeneku kumapangitsa ma transmitters a kutentha kwa Pt100 kukhala magawo ofunikira pamakina opangira makina ndi kuwongolera, zomwe zimathandizira kuphatikiza kosasinthika ndi zida ndi njira zomwe zilipo kale. Poganizira kugwiritsa ntchito chosinthira kutentha kwa RTD, magawo angapo ofunikira ayenera kuganiziridwa. Izi zikuphatikizapo kugwirizana kwa ndondomeko, kuya kwa kuika, ndi kukula kwa ndodo, zomwe zingakhudze kwambiri kulondola ndi kudalirika kwa kuyeza kwa kutentha. Kuphatikiza apo, mankhwalawa amapezekanso muzosankha zowononga kuphulika ndi thermowell, kuwonetsetsa kuti chitetezo ndi kulimba m'malo ovuta a mafakitale..Zosankha zazizindikiro zotulutsa zikuphatikizapo 4-20mA, RS-485, ndi HART protocol, zomwe zimapangitsa kuti zidazo zigwirizane ndi kayendetsedwe ka mafakitale osiyanasiyana. machitidwe.

Ife, Shanghai Wangyuan Instruments of Measurement Co., Ltd. ndi kutsogolera Chinese mkulu-chatekinoloje ogwira okhazikika mu mafakitale ndondomeko ulamuliro luso ndi mankhwala kwa zaka zambiri ndi kupereka mkulu khalidwe customizable.ma transmitters otenthayokhala ndi Pt100 sensor element kuti ikwaniritse zofuna zamtundu uliwonse.
