Inzwa yezinga lethangi le-S5-200 yensimbi engagqwali engu-304 ephumayo engu-4-20mA iyisixazululo esihlala isikhathi eside nesithembekile esiklanyelwe izimoto zentengiso, amasethi amajeneretha, kanye nezinhlelo ezibanzi zokuphatha izimoto zezimoto. Idizayinelwe ukuhlinzeka ngokuqapha kweleveli yoketshezi okuqhubekayo nokunembayo, le nzwa ihlanganisa ngaphandle komthungo kuma-telematics wesimanje kanye nezakhiwo zokulawula izimboni. Ngokuletha idatha enembile kaphethiloli, isiza abaqhubi bemikhumbi ukuthi bathuthukise ukusetshenziswa kukaphethiloli, bathole okudidayo, futhi bathuthukise ukusebenza kahle kukonke kuzo zonke izindawo zokuphakela ezihlukahlukene.
I-Rugged Stainless Stainless 304 Construction
Yakhiwe ngensimbi engagqwali yekhwalithi ephezulu engu-304, le nzwa inikezela ukumelana nokugqwala okuhle kakhulu nokuqina okukhethekile kokusebenza. Izicelo zezimboni kanye nemishini ephathwayo ivamise ukusebenza ezindaweni ezinzima lapho amathangi kaphethiloli ehlala echayeka ezimweni zezulu ezimbi kakhulu, ukudlidliza okukhulu, kanye nokungcola koketshezi olunamandla. Izindlu eziqinile zensimbi engagqwali engu-304 ziqinisekisa ukuthi inzwa igcina ubuqotho bayo besakhiwo kanye nokunemba kokulinganisa esikhathini eside sokusebenza, kunciphisa kakhulu isidingo sokunakekelwa njalo nokwehlisa izindleko eziphelele zobunikazi bamaqembu okuthenga.
I-PCB eyakhelwe ngaphakathi ku-Head Unit & 4-20mA Output
Inzuzo eyinhloko yezobuchwepheshe yale nzwa yezinga i-PCB eyakhelwe ngaphakathi kuyunithi yekhanda. Ngokwakhela ama-electronics okucubungula amasignali abalulekile ngaphakathi kweyunithi yekhanda elihlangene, umklamo ukhulisa ukusebenza kahle kwesikhala kuyilapho uvikela izingxenye ezizwelayo ekucindezelekeni kwangaphandle kwemvelo. Le ndlela ehlanganisiwe iqinisekisa ukuguqulwa kwesignali ngokushesha emthonjeni. Ngaphezu kwalokho, okukhiphayo okujwayelekile kwemboni ye-4-20mA kunikeza ukudluliswa kwedatha ye-analog ezinzile ebangeni elide. Iluphu yamanje engu-4-20mA imelana ngokwemvelo nokuphazamiseka kazibuthe kagesi (EMI) kanye nokwehla kwamandla kagesi, iqinisekisa ukuthi i-Programmable Logic Controllers (PLCs) noma amadeshibhodi akho okulandelela izimoto athola ukufundwa kwezinga likaphethiloli okuthembeke kakhulu.
Ukuthunyelwa Okujwayelekile Nezimo Zokusebenza
Ngenxa yomklamo wayo oguquguqukayo kanye nokuphumayo kwesignali okuthembekile, le nzwa yezinga ivumelana nezimo ezihlukahlukene zezinhlelo zokusebenza zezimboni, ezentengiso, neselula. Ukuthunyelwa okujwayelekile kufaka:
- Amathangi okugcina amakhemikhali ephethroli, amadepho kaphethiloli, kanye nezindawo zokudluliswa kwamapayipi: Ukuhlinzeka ngokuqapha okubalulekile kwempahla kanye nokuvimbela ukuchichima ekufuneni ingqalasizinda kawoyela negesi.
- Izihlanzi zokuhlanza amanzi, imithombo yemigodi, nemithombo emanzi yesiteshi sokuphakamisa: Ukuqinisekisa ukulawulwa kwezinga loketshezi olunembile kanye nokusebenza okuthembekile ezindaweni zokulawulwa kwamanzi zikamasipala noma zezimboni.
- Amathangi osuku lukadizili ama-genset nama-offshore rigs lapho i-EMI inzima khona: Iletha amasiginali azinzile ngisho nasezindaweni ezibuswa umsindo omkhulu kagesi nemishini esindayo.
- Izisele zokudla neziphuzo ezinokufakwa kwe-tri-clamp okuhlanzekile: Ukusekela izidingo zokucubungula ukuhlanzeka ngenkathi kugcinwa ukukalwa kwevolumu okunembile nokuqhubekayo.
- Imishini ephathwayo (ama-excavators, izitimela) ephakelayo i-PLC noma i-SCADA DCS ngamakhadi e-analogi angu-4–20 mA: Ukuhlanganisa kalula namasistimu okulawula imishini esindayo ukuze kuthuthukiswe ukusetshenziswa kukaphethiloli nokuthuthukisa ukulandelelwa kwempahla yeselula.
Kungakhathaliseki ukuthi uthuthukisa izindawo zokugcina zezimboni ezimile noma usebenzisa inethiwekhi yokuphathwa kwezimoto ezithuthukisiwe, le nzwa yezinga lokukhiphayo engu-4-20mA iletha ukwethembeka, ukukhuthazela kwemvelo, nokuzinza kwesignali okudingekayo ukuze kusekelwe izinqumo zokusebenza ezibalulekile.
