Xov xwm - Dab tsi yog qhov conductivity sensor hauv dej?

Conductivity yog ib qho kev siv ntau yam kev ntsuas hauv ntau yam kev siv, suav nrog kev ntsuas dej purity, rov qab osmosis xyuas, ntxuav cov txheej txheem validation, tshuaj txheej txheem tswj, thiab kev lag luam dej khib nyiab.

Lub conductivity sensor rau aqueous ib puag ncig yog ib qho khoom siv hluav taws xob tsim los ntsuas cov hluav taws xob conductivity ntawm dej.

Nyob rau hauv txoj cai, cov dej ntshiab ua pov thawj tsis zoo hluav taws xob conductivity. Cov hluav taws xob conductivity ntawm dej feem ntau yog nyob ntawm qhov concentration ntawm ionized tshuaj yaj nyob rau hauv nws - xws li, nqi hais xws li cations thiab anions. Cov ions no yog los ntawm qhov chaw xws li cov ntsev ntau (piv txwv li, sodium ions Na⁺ thiab chloride ions Cl⁻), cov zaub mov (piv txwv li, calcium ions Ca²⁺ thiab magnesium ions Mg²⁺), acids, thiab bases.

Los ntawm kev ntsuas hluav taws xob conductivity, lub sensor muab kev ntsuam xyuas tsis ncaj ntawm qhov tsis muaj xws li tag nrho cov khoom tawg (TDS), salinity, lossis qhov loj ntawm ionic paug hauv dej. Cov nqi hluav taws xob siab dua qhia tau tias muaj ntau dua ntawm cov ions yaj thiab, yog li ntawd, txo cov dej purity.

Txoj Cai Ua Haujlwm

Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm lub conductivity sensor yog raws li Ohm txoj cai.

Cov khoom tseem ceeb: Conductivity sensors feem ntau siv ob-electrode los yog plaub-electrode configurations.
1. Daim ntawv thov hluav taws xob: Ib qho hluav taws xob hloov pauv yog siv hla ib khub ntawm electrodes (cov tsav tsheb electrodes).
2. Ion migration: Nyob rau hauv lub zog ntawm hluav taws xob teb, ions nyob rau hauv cov kev daws migrate mus rau electrodes ntawm opposite nqi, tsim ib tug hluav taws xob tam sim no.
3. Kev ntsuas tam sim no: qhov tshwm sim tam sim no yog ntsuas los ntawm lub sensor.
4. Conductivity xam: Siv cov paub siv voltage thiab ntsuas tam sim no, lub kaw lus txiav txim siab hluav taws xob tsis kam ntawm cov qauv. Conductivity yog muab los ntawm lub sensor lub geometric yam ntxwv (electrode cheeb tsam thiab inter-electrode nrug). Txoj kev sib raug zoo yog qhia raws li:
Conductivity (G) = 1 / Resistance (R)

Txhawm rau txo qhov ntsuas qhov tsis raug tshwm sim los ntawm electrode polarization (vim cov tshuaj tiv thaiv electrochemical ntawm lub electrode nto) thiab cov teebmeem capacitive, niaj hnub conductivity sensors siv alternating tam sim no (AC) excitation.

Hom Conductivity Sensors

Muaj peb yam tseem ceeb ntawm conductivity sensors:
• Ob-electrode sensors yog tsim rau cov dej ntshiab huv thiab kev ntsuas qis.
Plaub-electrode sensors yog ua hauj lwm rau nruab nrab mus rau high-conductivity ranges thiab muab kev tiv thaiv zoo rau fouling piv rau ob-electrode designs.
• Inductive (toroidal los yog electrodeless) conductivity sensors yog siv rau nruab nrab mus rau siab heev conductivity theem thiab muaj superior tiv thaiv kab mob vim lawv cov kev ntsuas tsis sib cuag.
