Emerson anounza mavharuvhu ane certification yeSIL matatu

Emerson akaunza mavharuvhu ekutanga anosangana nezvinodiwa zvekugadzira zveSafety Integrity Level (SIL) 3 zvichienderana neInternational Electrotechnical Commission's IEC 61508 standard. Aya maFisherKuzviparadzanisa neDigitalMhinduro dzekupedzisira dzechinhu dzinopa zvinodiwa nevatengi vemavharuvhu ekuvharika muzvirongwa zveCritical Safety Instrumented System (SIS).

Pasina mhinduro iyi, vashandisi vanofanira kudoma zvikamu zvese zvevharuvhu, votenga chimwe nechimwe, vozvibatanidza kuita chinhu chinoshanda chose. Kunyangwe matanho aya akaitwa nemazvo, rudzi urwu rwekusangana kwakagadzirwa nemaoko haruzopi zvese zvakanakira kuungana kweDigital Isolation.

Kugadzira vharuvhu yekudzima vharuvhu yekudzivirira vharuvhu ibasa rakaoma. Mamiriro ezvinhu akajairwa uye ekusagadzikana anofanirwa kuongororwa nekunzwisiswa nekungwarira pakusarudza zvikamu zvevharuvhu neactuator. Pamusoro pezvo, musanganiswa wakakodzera we solenoids, mabhureki, ma couplings nezvimwe zvinhu zvakakosha zvinofanirwa kutsanangurwa uye kuenzaniswa nekungwarira nevharuvhu yakasarudzwa. Chimwe nechimwe chezvinhu izvi chinofanira kushanda chimwe nechimwe uye pamwe chete kuti chishande.

Emerson anobata nyaya idzi nedzimwe nekupa mubatanidzwa wevharuvhu yekuvharira yeDigital Isolation yakagadzirwa nemainjiniya, yakagadzirirwa maitiro ese. Zvikamu zvakasiyana-siyana zvinosarudzwa zvakanangana nezvinodiwa zvekushandisa. Mubatanidzwa wese unotengeswa seyuniti yakaedzwa zvizere uye ine certification, ine nhamba imwe chete yeserial uye magwaro anoenderana anotsanangura ruzivo rwechikamu chimwe nechimwe chemubatanidzwa.

Nekuti gungano iri rakagadzirwa semhinduro yakakwana muzvivakwa zveEmerson, rine mukana wekuti rikanganise panodiwa (PFD) rate. Mune zvimwe zviitiko, mwero wekukanganisika kwegungano iri uchava wakaderera ne50% pane musanganiswa wezvikamu zvevharuvhu zvakafanana zvakatengwa chimwe nechimwe uye zvakaunganidzwa nemushandisi wekupedzisira.
