Electrochemical Dissolved Oxygen Sensor

Esi sivamvo se-oksijini esinyibilikisiweyo se-electrochemical sisebenzisa umgaqo womlinganiselo we-amperometric we-electrochemical, kunye nokusetyenzwa komqondiso odibeneyo wedijithali, owakhelwe{0}}kwimbuyekezo yobushushu obuzenzekelayo kunye ne-IP68 ubume obungangeni manzi. Ixhasa umgangatho we-RS485 Modbus{4}}imveliso yedijithali ye-RTU, ebonisa uzinzo oluphezulu, ukukhukuliseka okuphantsi, ukuchasana okunamandla{5}}nokuphazamiseka kunye nobomi benkonzo ende. Isetyenziswa ngokubanzi kwi-aquaculture, unyango lwe-lindle, ukubeka iliso kokusingqongileyo, i-brewery kunye neenkqubo zamanzi zamachiza, kwaye inokudityaniswa ngokuthe ngqo ne-PLC, i-DCS kunye nabalawuli bechungechunge lwe-MTW.

Esi sivamvo se-electrochemical esinyibilikisiweyo semizi-mveliso {{0} yenzelwe ukujonga ioksijini enyibilikisiweyo ixesha elide-kwi-intanethi (DO) kwiindawo ezahlukeneyo zamanzi. Yamkela i-amperometric ezintathu -inkqubo ye-electrode electrochemical (i-electrode esebenzayo, i-electrode yereferensi, i-electrode ye-counter), ecinezela ngokufanelekileyo i-electrode polarization kunye nokunciphisa ukuphazamiseka kwi-hydrogen sulfide, i-carbon dioxide kunye nezinye izinto, iqinisekisa umlinganiselo ozinzileyo nochanekileyo. -Ukusebenza okuphezulu kwe-membrane ekwazi ukutyhutyha ihlukanisa izinto eziqinileyo nezingcolisayo, ikhusela i-electrolyte yangaphakathi kunye ne-electrode system.

Yakhelwe-phezulu-isivamvo sobushushu esichanekile ibona imbuyekezo yobushushu obupheleleyo{2}}kuluhlu oluzenzekelayo, ilungisa iimpazamo ezibangelwa lutshintsho lobushushu bamanzi. Iprobe iyonke ithatha imeko yedijithali kunye noyilo lokwahlulwa kombane, ngobuchule obunamandla obuchasa-ukuphazamiseka kombane, ukuxhasa ukuhanjiswa kwedatha okude{5}}kumgama ngeRS485 Modbus{7}}RTU. Indlu yenziwe ngomhlwa{9}}iPPS/PEEK exhathisa iplastiki yobunjineli kunye ne316L yentsimbi estainless, enonyango olugudileyo oluchasene{11}}nonyango lomphezulu, olulungele ukufakela ixesha elide{12}}lokufakela ngaphantsi kwamanzi.

Ixhasa umgangatho omnye-inqaku elinye kunye neengongoma ezimbini-zokulinganisa inqaku (i-zero yokulinganisa ioksijini, ulungelelwaniso lweoksijini ehluthisiweyo), kunye namandla okulungelelaniswa kwedatha{2}}ukucima ugcino kunye nempazamo{3}}yokuxilonga imisebenzi. I-membrane engenekayo endaweni kunye noyilo lwemodyuli ye-electrolyte yenza ugcino lube lula kwaye lucuthe kakhulu-indleko zokusebenza kwexesha elide. Inozinzo olugqwesileyo kwaye ingaqhuba ngokuqhubekayo ixesha elide kumachibi e-aquaculture, iitanki zomoya kunye neetanki ze-biochemical reaction.
