Qhov tseem ceeb ntawm cov kua theem sensor yog nws lub peev xwm ntsuas, uas suav nrog kev ntsuas ntau, qhov tseeb, thiab kev daws teeb meem. Qhov ntsuas qhov ntsuas qhia tau hais tias qhov ntev ntawm cov kua siab qhov ntsuas lub peev xwm ntsuas tau -piv txwv li, 0-2 meters lossis ntau dua. Kev ntsuas qhov tseeb qhia txog qhov loj ntawm qhov yuam kev hauv qhov kev tshawb pom, feem ntau qhia tias ± 0.5% ntawm tag nrho cov nplai. Kev daws teeb meem, lub sijhawm no, txhais cov kev hloov pauv me tshaj plaws hauv cov kua theem uas lub sensor tuaj yeem paub qhov txawv ntawm -ib qho tseem ceeb rau kev tswj cov qib kua.
Lub teeb liab tso zis ua haujlwm ua qhov ntsuas qhov tseem ceeb rau cov kua theem sensors. Cov ntawv tso zis ntau muaj xws li cov teeb liab analog, cov teeb liab tam sim no, hloov cov teeb liab, thiab cov teeb liab digital. Analog thiab tam sim no cov cim qhia tau zoo- haum rau kev soj ntsuam cov kua dej txuas ntxiv; Hloov cov teeb liab tuaj yeem siv rau lub tswb ntsuas dej lossis kev tswj xyuas yooj yim; thaum sensors nruab nrog cov interfaces tuaj yeem xa cov ntaub ntawv ncaj qha los ntawm kev sib txuas lus raws tu qauv, yog li ua kom yooj yim rau kev saib xyuas tej thaj chaw deb thiab kev tswj hwm.
Kev khiav hauj lwm ib puag ncig thiab hluav taws xob tsis zoo yog qhov tseem ceeb sib npaug. Cov kua theem sensors feem ntau xav tau kev sib raug zoo nrog rau qhov kub thiab txias hom, ntxiv rau kev muaj peev xwm tiv thaiv dej thiab plua plav (piv txwv li, IP65 lossis IP67 kev ntsuas). Cov tsis muaj hluav taws xob-xws li kev khiav hauj lwm voltage thiab kev siv hluav taws xob- sib txawv ntawm cov qauv sib txawv thiab yuav tsum raug xaiv raws li cov kev cai tshwj xeeb. Los ntawm kev soj ntsuam xyuas cov kev txwv no, ib tus tuaj yeem ua kom ntseeg tau tias cov kua theem sensor ua haujlwm ruaj khov thiab ntseeg tau thoob plaws ntau qhov chaw, suav nrog kev lag luam, thaj chaw, thiab kev ua liaj ua teb.
