Emerson anosuma SIL 3-yakasimbiswa mavharuvhu magungano

Emerson akaunza mavharuvhu ekutanga anosangana nemaitiro ekugadzira zvinodiwa zveSafety Integrity Level (SIL) 3 maererano neInternational Electrotechnical Commission's IEC 61508 standard. Fisher idziDigital Isolationyekupedzisira element mhinduro dzinoshanda zvinodiwa nevatengi zvekuvhara mavharuvhu mune yakakosha kuchengetedza instrumented system (SIS) application.

Pasina mhinduro iyi, vashandisi vanofanirwa kutsanangura ese mavharuvhu ega ega ega, atore imwe neimwe, uye oaunganidza kuita yese inoshanda. Kunyange kana matanho aya akaitwa nemazvo, rudzi urwu rwegungano retsika harisati richizopa mabhenefiti ese eDigital Isolation assembly.

Injiniya yevhavhavhavha yekudzivirira ibasa rakaoma. Izvo zvakajairika uye zvinogumbura maitiro maitiro anofanirwa kuongororwa uye kunzwisiswa pakusarudza valve uye actuator zvikamu. Mukuwedzera, kusanganiswa kwakakodzera kwema solenoids, mabhuraketi, kubatanidza uye zvimwe zvakakosha hardware zvinofanira kutsanangurwa uye zvakanyatsoenderana nevhavha yakasarudzwa. Chimwe nechimwe chezvikamu izvi chinofanira kushanda chega uye mumakonti kuti chishande.

Emerson anogadzirisa izvi nedzimwe nyaya nekupa yakagadziridzwa Digital Isolation yekuvhara valve musangano, yakagadzirirwa kune yega yega maitiro. Izvo zvikamu zvakasiyana-siyana zvinosarudzwa zvakananga kugutsa zvinodiwa zvekushandisa. Gungano rose rinotengeswa seyuniti yakaedzwa zvizere uye yakasimbiswa, ine nhamba imwe chete yeserial uye zvinyorwa zvinobatanidzwa zvinotsanangura zvakadzama zvechikamu chega chega chegungano.

Nekuti gungano rakavakwa semhinduro yakakwana muzvivakwa zveEmerson, inozvirumbidza neyakavandudzwa zvakanyanya mukana wekutadza pakuda (PFD) chiyero. Mune zvimwe zviitiko, kukundikana kwegungano kuchasvika ku50% zvishoma kudarika kusanganiswa kwezvikamu zvakafanana zvevharuvhu zvakatengwa mumwe nomumwe uye zvakaunganidzwa nemushandisi wekupedzisira.
