M'mafakitale amankhwala, kuyeza kuchuluka kwamadzimadzi molondola komanso modalirika ndikofunikira kuti magwiridwe antchito asamayende bwino.Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri kutali ndi telemetry signal liquid level sensors ndi static pressure liquid level transmitter.Njirayi imawerengera mlingo wamadzimadzi poyesa kuthamanga kwamadzimadzi m'chombocho.M'nkhaniyi, tikambirana mfundo zazikuluzikulu zosankhidwa ndi momwe mungagwiritsire ntchito sensa ya XDB502 yamadzimadzi pazida zamankhwala.
Mbali ndi Ubwino wake
Sensa ya XDB502 yamadzimadzi imakhala ndi zinthu zingapo komanso zabwino zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu yosiyanasiyana yazomera zama mankhwala.Izi zikuphatikizapo:
Kugwira ntchito m'malo otentha kwambiri, kuthamanga kwambiri, kukhuthala kwambiri, komanso malo owononga kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mitundu ingapo.
Kuyeza kwakukulu komwe kumasiyanasiyana malinga ndi dera, ndipo palibe mawanga akhungu.
Kudalirika kwakukulu, kukhazikika, moyo wautali, ndi ndalama zochepa zosamalira.
Muyezo wolondola kwambiri, wolondola mpaka +0.075% sikelo yathunthu (fs) ya ma transmitters otuluka kunja kwa static pressure fluid ndi +0.25% fs pama transmitters amtundu wapakhomo wa static pressure fluid level.
Kudzizindikiritsa mwanzeru komanso magwiridwe antchito akutali.
Zosankha zosiyanasiyana zotulutsa ma siginecha, kuphatikiza ma protocol osiyanasiyana amasigino apano a 4mA-20mA, ma pulse sign, ndi ma siginecha olankhulirana a fieldbus.
Zosankha
Posankha static pressure liquid level transmitter, mfundo zotsatirazi ziyenera kuganiziridwa:
Ngati mulingo wofananira (kuthamanga kosiyana) ndi wochepera 5KPa ndipo kachulukidwe wa sing'anga yoyezera asintha kuposa 5% ya mtengo wamapangidwe, cholumikizira chosiyana chamadzimadzi sichiyenera kugwiritsidwa ntchito.
Kutentha kwamadzimadzi, kuphulika, kawopsedwe, corrosiveness, mamasukidwe akayendedwe, kukhalapo kwa tinthu tating'onoting'ono, chizolowezi cha evaporation, komanso chizolowezi cha condense pa kutentha kozungulira ziyenera kuganiziridwa posankha cholumikizira.
Transmitter imatha kupangidwa ndi ma flanges amodzi kapena awiri.Kwa ma transmitters awiri a flange, kutalika kwa capillary kuyenera kukhala kofanana.
Pazamadzimadzi omwe amakonda crystallization, sedimentation, high viscosity, coking, kapena polymerization, diaphragm type differential pressure fluid transmitter yokhala ndi njira yosindikiza yoyikapo iyenera kusankhidwa.
M'malo omwe gawo la gasi limatha kukhazikika ndipo gawo lamadzimadzi limatha kusanduka nthunzi, ndipo chidebecho chimakhala ndi kutentha kwambiri komanso kupanikizika kwambiri, cholumikizira, chopatula, ndi chidebe choyezera chiyenera kukhazikitsidwa mukamagwiritsa ntchito chosinthira chosiyana siyana chamadzimadzi. kuyeza kwa mlingo wamadzimadzi.
The masiyanidwe kuthamanga madzi mlingo transmitter zambiri amafuna osiyanasiyana kutembenuka.Chifukwa chake, chotumiziracho chiyenera kukhala ndi magwiridwe antchito osiyanasiyana, ndipo kuchuluka kwake kuyenera kukhala osachepera 100% ya malire apamwamba amtunduwu.Posankha cholumikizira, chotsitsacho chiyenera kuganiziridwa, makamaka poyezera zowulutsa kwambiri.Chifukwa chake, mtundu wa transmitter uyenera kusankhidwa kutengera momwe zinthu ziliri.
Kagwiritsidwe Ntchito
The XDB502 fluid level sensor ili ndi zinthu zingapo zogwiritsira ntchito zomwe ziyenera kuganiziridwa:
Kutentha kwa ndondomeko: Ma transmitter amtunduwu amagwira ntchito popereka mphamvu kudzera mumadzi odzaza osindikizidwa mkati mwa chipangizocho.Zakumwa zodzaza wamba zimaphatikizapo silicone 200, silikoni 704, ma chlorinated hydrocarbons, zosakaniza za glycerol ndi madzi, pakati pa ena.Madzi aliwonse odzaza amakhala ndi kutentha koyenera, ndipo mtundu wodzaza uyenera kusankhidwa kutengera mankhwala a sing'anga yoyezera komanso kutentha kwa ndondomeko.Choncho, pamene kutentha kwa ndondomekoyi kupitirira 200 ℃, kugwiritsa ntchito transmitter yosindikizidwa ndi diaphragm kuyenera kuganiziridwa bwino.Ngati ndi kotheka, makina osindikizira otalikirapo kapena chipangizo chowongolera matenthedwe ayenera kusankhidwa, ndipo wopanga ma transmitter atsimikizire tsatanetsatane.
Kutentha kozungulira: Madzi odzaza ayenera kudzazidwa ndi kutentha koyenera.Capillary iyenera kukhala yogwirizana ndi kutentha kwamadzi odzaza.Monga epoxyethane mu zipangizo zoyaka moto EOEG sachedwa polymerization, diaphragm-osindikizidwa differential kuthamanga madzi mlingo transmitter ayenera kugwiritsidwa ntchito kuyeza epoxyethane sing'anga mlingo wa.Popeza njira za carbonate zimakhala zosavuta kuti crystallization, makina osindikizira a diaphragm osindikizidwa omwe ali ndi makina osindikizira amayenera kugwiritsidwa ntchito, ndi malo oyikapo ndi khoma lamkati la chipangizocho.Kuyika kwake kwakunja ndi kutalika kwake kumatsimikiziridwa potengera zida za zida.Pazida zokhala ndi kutentha kwa 250 ℃ kapena kupitilira apo, payipi yoponderezedwa iyenera kugwiritsidwa ntchito.
Mapeto
Pomaliza, XDB502 fluid level sensor ndi njira yodalirika komanso yolondola yoyezera milingo yamadzimadzi muzomera zama mankhwala.Ili ndi maubwino angapo, kuphatikiza kusiyanasiyana, kulondola kwambiri, njira zosiyanasiyana zotulutsira ma siginolo, komanso kudzizindikiritsa mwanzeru.Posankha chotumizira, zinthu zamadzimadzizo, monga kuyaka, kuphulika, kawopsedwe, kuwononga, ndi kukhuthala kwake, ziyenera kuganiziridwa.Kuphatikiza apo, zinthu zogwiritsiridwa ntchito monga kutentha kwa ndondomeko ndi kutentha kozungulira ziyenera kuganiziridwa kuti zitsimikizidwe zolondola komanso zodalirika.
