CET-8311 Piezo Traffic Sensoryog cov cuab yeej ua haujlwm siab tsim los sau cov ntaub ntawv tsheb khiav. Txawm hais tias tau teeb tsa mus tas li lossis ib ntus, CET-8311 tuaj yeem hloov kho tau yooj yim rau ntawm lossis hauv qab txoj kev, muab cov ntaub ntawv xov xwm raug. Nws cov qauv tsim tshwj xeeb thiab cov qauv tiaj tus tso cai rau nws ua raws li txoj kev profile, txo cov suab nrov ntawm txoj kev, thiab txhim kho qhov tseeb thiab kev ntseeg siab ntawm kev sau cov ntaub ntawv.
Ob hom rau CET-8311 Piezo Traffic Sensor:
Chav Kawm I (Weigh In Motion, WIM): Siv rau kev siv lub cev hnyav, nrog cov khoom siv sib xws ntawm ± 7%, haum rau cov ntawv thov uas xav tau cov ntaub ntawv hnyav hnyav.
Chav Kawm II (Classification): Siv rau kev suav tsheb, kev faib tawm, thiab kev tshawb nrhiav ceev, nrog rau cov khoom sib xws ntawm ± 20%. Nws yog kev lag luam ntau dua thiab tsim nyog rau kev tswj xyuas tsheb loj.
Lub ntsiab nta ntawm CET-8311 Piezo Traffic Sensor
1.Ua kom tag nrho, tsis muaj cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ua rau muaj kev cuam tshuam.
2.Kev ua tau zoo heev hauv kev ntsuas dynamic, tshawb xyuas cov ntaub ntawv ib leeg-qag hauv lub sijhawm, nrog kev sib cais ntawm qhov nruam loads.
3.Simple installation nrog tsawg txoj kev puas tsuaj, yuav tsum tau ib tug trench ntawm 20 × 30 hli.
4.Integrated nrog txoj kev, tsis muaj kev cuam tshuam los ntawm nag, daus, dej khov, los yog te, tsis muaj kev tu ncua.
5.Installed flush nrog txoj kev nto, ua kom txoj kev du rau tsheb.
6.Parallel ua nrog lub sensor thiab ua module, kom ntseeg tau ceev cov ntaub ntawv tuav.
7.Lub sensor yog embedded rau hauv txoj kev thiab hauv av kom nyob twj ywm flush nrog txoj kev nto. Lub sensor ua module ua hauj lwm nyob rau hauv parallel, tso cai rau kom ceev cov ntaub ntawv ua tsis tau ploj los yog tsis tseeb. Lub sensor raug ntes cov teeb liab hluav taws xob nyob ntev.
8.Txhim kho cov kab rov tav siab, kom ntseeg tau qhov tseeb ntsug quab yuam.
9.Lub neej ntev, tsis muaj kev tiv thaiv sab nraud, muaj peev xwm tiv taus ntau dua 40 lab qag hla.
10.Suitable rau txoj kab dav.
11.Txhim kho rau txoj kev hloov pauv yam tsis muaj kev cuam tshuam cov ntaub ntawv txheeb xyuas.
