Folasaga I Galuega a le PH Extension Ring

O le mama fa'aopoopo pH o se fa'apipi'i fa'apipi'i -mamanu fa'atusa-fa'apipi'i fa'apitoa mo faiga e fua ai le pH. E masani ona faʻapipiʻiina i le va o le pH electrode ma ana mea faigaluega faʻapitoa (e pei o faʻamau faʻapipiʻi, transmitters, poʻo fale faʻalogo). E le pei o fesoʻotaʻiga lautele masani, e sili ona lelei mo manaʻoga tulaga ese o faʻataʻitaʻiga o le pH, o loʻo i ai ni galuega autu se tolu ma tulaga taua faʻapitoa, ma avea ai ma vaega autu mo le faʻamautinoaina o le mataʻituina o le pH saʻo ma mautu:

Galuega Autu
Fegalegaleaiga Felagolagomai: E galue o se "liliu" mo fesoʻotaʻiga le fetaui.

O uiga autu o faʻatinoga o le pH faʻalauteleina mama e faʻaalia i lona fetuutuunai, puipuiga, mautu, ma le faʻatinoina, lea o le a matou faʻamatalaina auiliili i lalo:
Fetuuna'i: E lagolagoina le tele-faaliliuina o filo, e fetaui ma feso'ota'iga masani e pei ole PG13.5, NPT, M16, ma G filo. O loʻo faʻaalia ai le saʻo maualuga, fetaui lelei filo (faapalepale Itiiti pe tutusa ma le ± 0.5mm), ma e leai se matala pe a maeʻa fesoʻotaʻiga, faʻamautinoa le leai o se faʻailoga faʻasalalau. E mafai ona ausia le faʻaleleia o vaega e aunoa ma le suia o mea uma e fua ai.

Fa'apalepale Si'osi'omaga: Mea e sili ona fetuutuunai; PTFE mafai ona tatalia acids malosi ma alkalis (e aofia ai hydrofluoric acid) ma le pH 0-14, ae 316L uamea stainless e talafeagai mo le faaituau/mildly corrosive ala o faasalalauga. Mea'ai -mea'ai (PTFE/316L) e ogatasi ma fa'ata'ita'iga FDA/GMP. O fa'ata'ita'iga masani e mafai ona tatalia -30tikeri –130tikeri, ma maualuga-fa'ata'ita'iga vevela e talafeagai mo faiga fa'amama. O nisi fa'ata'ita'iga lagolago I lalo ifo po'o le tutusa ma le 0.4MPa maualuga-omiga si'osi'omaga e aunoa ma se fa'alavelave fa'aletonu, talafeagai mo reactors fa'amaufa'ailoga ma isi fa'aoga.

Tulaga mautu: Fa'amaufa'ailoga sili ona lelei; fa'apipi'i O-fa'amaufa'ailoga mama (EPDM/PTFE material) e taofia ai le lepa o le ala fa'ata'ita'i ma le fa'aosoina o le pefu mai fafo ma le susu, puipuia le atina'e eletise mai le fa'aleagaina. O faʻataʻitaʻiga uʻamea e aofia ai le faʻavaeina e faʻaitiitia ai le faʻaogaina o le eletise mai mea faigaluega falesuesue ma faʻaliliuga faʻasalalau faʻapisinisi, faʻamautu le faʻaogaina o le eletise (I lalo ifo pe tutusa ma le 250MΩ) ma le puipuia o fesuiaiga o faʻamatalaga.

Fa'atino: O le umi e filifili ai (5mm–50mm) e mafai ai ona fetuunai sa'o o le loloto o le fa'aeletise, fa'amautinoa o lo'o fa'aofuina atoatoa le membrane ma'ale'ale i le vai su'esu'e a'o aloese mai fa'alavelave e pei o puipui o pusa ma mea fa'aoso. Mamafa ma faigofie ona faʻapipiʻi ma faʻapipiʻi, e aunoa ma ni laʻasaga faʻapipiʻi lavelave, e mafai ai ona faʻavave le faʻaogaina o le eletise mo le faʻavasegaina i fafo / fanua, e mafua ai le maualuga o le tausiga. E faigofie ona fa'amama lona ie lamolemole, ma e mafai ona tatalia le -maualuga vevela fa'ama'i i mea'ai/talavai.

O mama faʻalautele PH o mea faʻapipiʻi masani e faʻaaogaina i le alamanuia eletise e faʻafesoʻotaʻi ai insulators, meafaigaluega, ma isi vaega. O faʻataʻitaʻiga eseese e iai faʻamatalaga eseese ma faʻamaufaʻailoga, lea o le a matou faʻaalia auiliili i lalo:
