Imigca ye-instrumentation impulse yimibhobho emincinci esetyenziswa rhoqo ukudibanisa umbhobho wenkqubo okanye itanki kunye ne-transmitter okanye esinye isixhobo. Njengetshaneli yokudlulisa ephakathi, ziyinxalenye yekhonkco eliphambili lokulinganisa nokulawula kwaye zinokubonisa iingxaki ezininzi malunga noyilo kunye noyilo. Iingqwalasela ezipheleleyo kunye namanyathelo afanelekileyo kuyilo lwemigca ye-impulse ngokuqinisekileyo zinceda ukuqinisekisa ukulinganisa okuchanekileyo nokusebenzayo.
Ubude bokufakwa
Ngenxa yezizathu zezinye izinto, ubude becandelo lemigca ye-impulse ukusuka kwisixhobo ukuya kwinkqubo ejolise ngqo kucetyiswa ukuba bugcinwe bufutshane kangangoko ukuze kuphuculwe ixesha lokuphendula kwaye kuncitshiswe amathuba okuba kubekho impazamo. Ingakumbi kwi-differential pressure transmitter, ubude bemigca emibini ukusuka kwi-high & low pressure port ukuya kwisixhobo kungcono ukuba bufane.
Indawo yokuma
Ukubeka imigca ye-impulse ngokuchanekileyo kubalulekile ukuze kufundwe ngokuchanekileyo kwizicelo ezahlukeneyo zokulinganisa. Ingcinga ephambili kukuphepha ukubamba igesi emgceni we-liquid medium okanye ulwelo kumgca wegesi. Ukufakelwa ngokuthe nkqo kusetyenziswa xa i-process medium ilulwelo apho imigca ye-impulse ibaleka ngokuthe nkqo ukusuka kwinkqubo ukuya kwi-transmitter ukuvumela nayiphi na igesi ebambeke kwimigca ukuba ibuyiselwe kwinkqubo. Xa i-process medium iyigesi, ukufakwa okuthe tye kufuneka kusetyenziswe ukuvumela nayiphi na i-condensate ukuba ibuyele kwinkqubo. Kwimilinganiselo yenqanaba esekwe kwi-DP, imigca emibini ye-impulse kufuneka iqhagamshelwe kwiiports eziphakamileyo nezisezantsi kwiindawo ezahlukeneyo eziphakamileyo.
Ukukhetha izinto
Izinto zomgca we-impulse kufuneka zihambelane ne-process medium ukuthintela ukurhawuzelelwa, ukugqwala okanye ukonakala. Ukhetho oluqhelekileyo oluqhelekileyo yintsimbi engagqwaliyo. Ukusetyenziswa kwezinye izinto ezifana ne-PVC, ubhedu okanye ii-alloys ezikhethekileyo kuxhomekeke kwiimpawu ze-medium.
Ubushushu kunye noxinzelelo
Imigca ye-impulse kufuneka yenzelwe ukunyamezela ubushushu kunye noxinzelelo olusebenzayo lwenkqubo. Ukwandiswa okuphakathi okanye ukuncipha kwimigca ye-impulse okubangelwa kukuguquguquka kobushushu kunokubangela ukufundwa okungazinzanga nokungachanekanga, okunokunciphisa ngokufakela i-insulation kwimigca. Icandelo lolwandiso lwe-helical lomgca we-impulse liyindlela yokonga indawo yokwandisa ubude ngokubanzi. Nangona ubude obuphezulu bunokuchaphazela ixesha lokuphendula kunye neminye imiba, yindlela esebenzayo yokupholisa i-medium kunye nokunciphisa uxinzelelo oluphezulu olukhawulezileyo ukukhusela i-transmitter.
Ulondolozo
Iintambo zoxinzelelo kufuneka zenzelwe ukufikelela lula ukuze kube lula ukugcinwa. Ukugcinwa rhoqo kubandakanya ukucocwa kweendawo ezivalekileyo, ukuhlolwa kokuvuza, ukujonga ubushushu obungenazintsholongwane, njl. Amanyathelo anjalo anokunceda ekuqiniseni ukusebenza okuthembekileyo nokuchanekileyo ekuhambeni kwexesha. Ukuhlolwa rhoqo kunye nokulinganiswa kuyacetyiswa ukuba kwenziwe nakwisixhobo.
Ukuvaleka kunye nokuvuza
Ukuvaleka kwemigca ye-impulse kungenzeka ngenxa yokuqokelelana kwamasuntswana okanye ukubanda okuphakathi. Ukuvuza kwe-medium kunokubangela ukulahleka koxinzelelo kunye nongcoliseko. Uyilo olufanelekileyo lwesakhiwo, ukuhlolwa rhoqo kunye nokukhetha izixhobo kunye nezitywino ezisemgangathweni kunokunceda ukuthintela iingozi.
Ukutyhafa kunye nokunyuka kwamandla
Iimpazamo zokulinganisa zinokubangelwa kukungcangcazela kwe-pulsation okanye ukunyuka koxinzelelo kwimigca yenkqubo. I-Dampener inokumelana ngempumelelo nokungcangcazela, inciphise ukuguquguquka koxinzelelo, ikhusele inkqubo ekugugeni okugqithisileyo. Ukusetyenziswa kwe-manifold ye-three-valve kuyakwazi ukwahlula i-transmitter kwinkqubo ngexesha le-pulsation ephezulu.
