CS3732 Conductivity Sensor

Kev Piav Qhia Luv:

electrode yog ib qho sensor tseem ceeb uas tsim los ntsuas lub peev xwm ntawm cov kua dej kom ua hluav taws xob, uas ncaj qha cuam tshuam nrog nws tag nrho cov concentration ntawm cov ions yaj. Qhov parameter tseem ceeb no yog qhov tseem ceeb rau kev ntsuam xyuas cov dej huv, tswj cov txheej txheem tshuaj lom neeg, thiab saib xyuas kev ua raws li ib puag ncig thoob plaws hauv kev lag luam xws li tshuaj, kev tsim hluav taws xob, khoom noj thiab dej haus, thiab kev kho dej khib nyiab.
Lub plawv ntawm lub electrode yog lub cell ntsuas uas muaj tsawg kawg yog ob lub ntsiab lus conductive. Thaum siv hluav taws xob hloov pauv, cov ions hauv cov tshuaj ua tiav lub voj voog ntawm cov ntsiab lus no. Qhov conductance tshwm sim raug ntsuas thiab, nrog rau lub cell's geometric constant (cell constant, K), yog siv los xam conductivity. Cov electrodes niaj hnub no yuav luag ib txwm koom ua ke nrog lub sensor kub (feem ntau yog Pt100 lossis Pt1000 RTD) rau kev them nyiaj tsis siv neeg, vim tias conductivity yog nyob ntawm qhov kub thiab txias heev. Cov qauv tsim feem ntau suav nrog ob-pole cells rau kev siv dav dav thiab plaub-pole (lossis plaub-electrode) cells, uas siv cov nplhaib tam sim no thiab voltage sib cais los txo cov teebmeem polarization thiab nthuav dav ntau yam kev ntsuas, tshwj xeeb tshaj yog hauv cov ntawv thov conductivity siab.
