Dej yog siv nyob rau hauv ntau cov ntawv thov, thiab ntau cov ntawv thov muaj nqis. Ib qho ntawm lawv yog kev soj ntsuam dej, thiab cov ntawv thov sib txawv, qee tus yuav tsum tsis muaj kev sib cuag nrog cov kua kom ua tiav kev tiv thaiv cov dej ua tau zoo. Yog li dab tsi yog cov ntsuas pom kom haum rau kev saib xyuas cov kua qib tsis pub saib xyuas?
Tsis yog kev sib cuag kom tau ntawm cov kua sensors, photoselectric lub hauv paus ntsiab lus thiab capacipitible, thiab ultrasonic kuj.
Tsis yog hu rau cov ntsiab lus, siv cov ntsiab lus kho qhov muag, koj tuaj yeem tiv thaiv peb kom muaj kev koom tes nrog cov qauv tsim), koj tuaj yeem paub cov khoom siv ntawm cov kua. Cov txiaj ntsig muaj xws li: Kev ntseeg siab, muaj qhov tseeb, ntau yam teeb tsa, thiab tsis tshua muaj neeg tua neeg av.
Tsis yog hu rau lub postinelectric qib sensors kuj tseem tuaj yeem pom tias qhov chaw tank nyob hauv txoj haujlwm lossis tsis yog.
Capacitive qib sensor, vim tias nws yog lub peev xwm capacitibe, yog li rau cov khoom siv tank uas tsis muaj xim hlau. Thib ob, cov tuab ntawm lub tank yuav tseem yuav cuam tshuam rau kev kuaj pom, yog li cov phab ntsa tuab ntawm lub tank kuj yuav tsum muaj. Txoj kev teeb tsa yog ze rau phab ntsa sab nraud ntawm cov dej tank nrhiav kom pom. Nws cov txiaj ntsig yog qhov yooj yim rau nruab thiab yooj yim siv. Tab sis piv nrog qib photoelectric qib sensor, qhov raug yog yuav tsawg. Haum rau cov khoom siv uas tsis tas yuav tsum muaj qhov ntsuas siab.
