1. Maikaʻi ka hana ʻana i nā wahi kemika ʻoi aku ka maikaʻi, ʻaʻohe mea polarized i hana ʻia e ka electrode i mea e pale ai i ka lepo, lepo a hoʻopili pū i ka uhi ʻana i nā phenomena e like me ka ʻilihuna, maʻalahi a maʻalahi hoʻi e hoʻouka no laila he ākea loa ia. o nā noi. Hoʻohana ʻia nā electrodes i kahi kiʻekiʻe o nā waikawa (e like me ka fuming sulfuric acid) kaiapuni.
2. Ka hoʻohana mika mika Pelekane, ka pololei kiʻekiʻe, a me ke kūpaʻa kiʻekiʻe.
3. ʻO ke ʻenehana ʻenehana conductivity hoʻopau i nā hewa clogging a me polarization. Hoʻohana ʻia i nā wahi āpau o nā uila uila e hana i ka blockage i loaʻa kahi hana kiʻekiʻe.
4. Sensor aperture nui, paʻa paʻa lōʻihi.
5. Hoʻokomo i ka laulā o nā paʻa a hoʻohana i ka hoʻonohonoho hoʻonohonoho hoʻoulu nui, hoʻonohonoho pono.
1. Kaomi kiʻekiʻe (pā): 1.6MP
2. Nā pono uila uila: PP, ABS, PTFE pono ʻole
3. Ka laulā ana: 0 ~ 10ms, 0 ~ 20ms, 0 ~ 200ms, 0 ~ 2000ms
4. Pololei (paʻa paʻa pūnaewele):. ± (+ 25 iā mākou e ana i ka waiwai o 0.5%)
5. Mea hoʻonoho: flow-through, pipeline, immersion
6. Nā hoʻonohonoho paipu: nā pae paipu 1 ½ a i ʻole PT NPT
7. Hana: 4-20mA a i ʻole RS485
ʻO ka conductivity kahi ana o ka hiki o ka wai e hala i ke kahe uila. Pili pono kēia hiki i ka hoʻoulu ʻana o nā iona i ka wai 1. ʻO kēia mau ion conductive mai nā paʻakai i hoʻoheheʻe ʻia a me nā mea nonorganic e like me alkalis, chlorides, sulfides a me carbonate compound. ʻoi aku nā ion i loaʻa, ʻo ke kiʻekiʻe o ka wai o ka wai. Pēlā nō, ʻo nā ioni liʻiliʻi i loko o ka wai, ʻoi aku ka liʻiliʻi o ka lawe ʻana. Hiki i ka wai hoʻomaʻemaʻe a deionized paha ke hana ma ke ʻano he insulator ma muli o ka haʻahaʻa (inā ʻaʻole hiki ʻole.
Hana nā ion i ka uila ma muli o kā lākou uku maikaʻi a maikaʻi ʻole 1. Ke hoʻoheheʻe ʻia nā electrolytes i loko o ka wai, ua hoʻokaʻawale lākou i nā mea i hoʻoili maikaʻi ʻia (cation) a hoʻopiʻi hewa ʻia (anion) ʻāpana. E like me ka hoʻokaʻawale ʻana o nā mea i hoʻoheheʻe ʻia i ka wai, noho paʻa nā pākana o kēlā me kēia uku maikaʻi a maikaʻi ʻole. ʻO ke kumu kēia ʻoiai ʻoi aku ka hoʻonui o ka wai o ka wai me nā ion i hoʻohui ʻia, noho mau ia me ka uila ʻole 2
Alakaʻi ʻia kumumanaʻo conductivity
Conductivity / Resistivity kahi laulā kālailai i hoʻohana ākea ʻia no ka hoʻomaʻemaʻe maʻemaʻe o ka wai, ka mālama ʻana i ka osmosis hope, nā kaʻina hana hoʻomaʻemaʻe, ka mālama ʻana i nā kaʻina hana kemika, a me ka wai hoʻoneoneo ʻenehana. ʻO nā hopena i hilinaʻi ʻia no kēia mau ʻano noi ʻokoʻa e pili ana i ke koho ʻana i ka mīkini conductivity kūpono. ʻO kā mākou alakaʻi hoʻomaikaʻi kahi kuhikuhi ākea a me ka mea hoʻomaʻamaʻa hoʻomaʻamaʻa e pili ana i nā makahiki o ke alakaʻi ʻana ʻoihana i kēia ana.
ʻO ka conductivity ka hiki i kahi mea e alakaʻi ai i ke au uila. Maʻalahi ke kumumanaʻo e ana ai nā mea kani i ka conductivity — hoʻonoho ʻia ʻelua mau papa i ka laʻana, hoʻopili ʻia ka mana ma nā pā (ma ke ʻano he anakahi uila nalu), a ana ʻia ke au e hala ana i ka hopena.
