Emerson waleta SIL 3-zizumizigwa zyamavwili

Emerson wakatalisya zibeela zyakusaanguna zyamavwili eezyo zizuzikizya ziyandikana zyakupanga zya Safety Integrity Level (SIL) 3 kweendelanya a International Electrotechnical Commission's IEC 61508 standard. Aaba BasikuzubaKuliimya kwa Dijitalinzila zyakumaninizya zigwasya basikuula kuti bajale mavwili muzibelesyo zyakukwabilila zipati (SIS).

Kakwiina nzila eeyi, babelesyi beelede kwaamba zibeela zyoonse zya valve, akuula chimwi achimwi, mpawo bazibunganye kuti zibeleke antoomwe. Nikuba kuti ntaamu eezyi zyachitwa kabotu, ooku kubunganya kwamusyobo ooyu takukonzyi kupa mpindu zyoonse zyakubunganya kwa Digital Isolation.

Kubamba vvalavu yakujala zyintu zyakukwabilila mulimo muyumu. Bwiime bwakuchita zintu buli kabotu abutali kabotu bweelede kulanga-langwa oobotu akuteelelwa aawo notusala zibeela zya valve a actuator. Mukuyungizya, kusanganya kweelede kwama solenoids, ma brackets, couplings azimwi zibelesyo ziyandikana kweelede kwaambwa akukozyanisigwa kabotu-kabotu ku valve yakasalwa. Chimwi achimwi chazibeela eezi cheelede kubeleka chilikke antoomwe kuti chibeleke.

Emerson ulalanga-langa twaambo ootu alimwi atumwi kwiinda mukupa nzila yakujala vvalavu ya Digital Isolation, yakabambilwa nzila imwi aimwi. Zibeela zisiyene-siyene zyakasalwa kuti zizuzikizye ziyandikana zyakubelesya. Muswaangano woonse ulasambalwa mbuli chintu chakasunkwa akuzumizigwa, anamba yomwe yamabala antoomwe amapepa aajatikizyidwe aatondezya twaambo twacibeela choonse chamuswaangano.

Nkaambo kakuti mbungano yakayakidwe mbuli nzila iimaninide mumaanda aa Emerson, ilalumbaizya kuti ilakonzya kugwasya kapati kuti kutabi kwaalilwa (PFD). Muziindi zimwi, mweelwe wakukachilwa kwakubunganya ulasika ku 50% munsi kwiinda kusanganya zibeela zya valve zyomwe zyakaulwa alikke akubunganizigwa amuntu uubelesya.
