Yuav ua li cas piezoelectric load cells ua haujlwm
Enviko 8311 sensor muab faib ua ob hom:
● Chav Kawm I Sensor (Hloov Hauv Kev Ua Si, WIM): Siv rau kev siv lub cev hnyav, nrog cov zis sib xws ntawm ± 7%, haum rau cov ntawv thov uas xav tau cov ntaub ntawv hnyav hnyav.
● Chav Kawm II Sensor (Classification): Siv rau kev suav tsheb, kev faib tawm, thiab kev tshawb nrhiav ceev, nrog rau cov zis sib xws ntawm ± 20%. Nws yog kev lag luam ntau dua thiab tsim nyog rau kev tswj xyuas tsheb loj
Daim ntawv thov teb
1.Kev saib xyuas kev tsheb khiav:
o Kev suav thiab kev faib tsheb.
o Kev saib xyuas kev khiav tsheb khiav, muab kev txhawb nqa cov ntaub ntawv tsheb thauj mus los.
2. Txoj Kev Tolling:
o Dynamic weight-based tolling, kom ntseeg tau tias kev sau tus xov tooj ncaj ncees thiab raug.
o Kev faib cov tsheb thauj mus los, txhim kho kev sau tus xov tooj.
3. Txoj Cai Lij Choj:
o Kev saib xyuas kev ua txhaum cai ntawm lub teeb liab thiab kev kuaj xyuas kom ceev, pab tswj kev khiav tsheb.
4.Intelligent Transportation Systems:
o Kev koom ua ke nrog kev tswj hwm kev tsheb, txhawb kev txhim kho kev txawj ntse kev thauj mus los.
o Cov ntaub ntawv tsheb thauj mus los thiab kev tshuaj xyuas, muab lub hauv paus rau kev npaj tsheb.

Installation Methods thiab cov kauj ruam
1. Kev npaj kev teeb tsa:
o Xaiv ib txoj kev uas tsim nyog, ua kom muaj kev ruaj ntseg mus sij hawm ntev ntawm cov khoom hnyav thiab kev nruj ntawm txoj kev hauv paus.
2.Qhov txiav:
o Siv lub tshuab txiav txiav los txiav cov qhov ntawm qhov chaw xaiv, ua kom muaj kev tswj xyuas meej ntawm qhov qhov ntev.
1) Hla ntu dimension
A = 20mm (± 3mm) hli; B = 30 (± 3mm)mm
2) Groove ntev
Qhov ntev ntawm lub qhov yuav tsum yog ntau tshaj 100 mus rau 200 hli ntawm tag nrho qhov ntev ntawm lub sensor. Tag nrho ntev ntawm sensor:
oi = L + 165mm, L yog rau tooj dag ntev (Saib daim ntawv lo).
3. Ntxuav thiab ziab:
o Ntxuav lub installation qhov nrog lub tshuab nqus tsev siab, kom ntseeg tau tias lub qhov yog tsis muaj khib nyiab.
4.Pre-installation Testing:
o Ntsuam xyuas lub capacitance thiab tsis kam ntawm lub sensor, kom ntseeg tau tias lawv nyob rau hauv specification.
5.Txhim kho cov kab nrib pleb:
o Muab lub ntsuas ntsuas thiab teeb tsa rau hauv lub qhov, txhim kho lub bracket txhua 15 cm.
6.Grouting:
o Sib tov cov khoom siv grouting raws li qhov piv txwv thiab sau lub qhov sib npaug, kom ntseeg tau tias qhov chaw grouting yog me ntsis siab dua ntawm txoj kev.
7. Nto sib tsoo:
o Tom qab cov grouting tau kho lawm, grind lub nto nrog lub kaum sab xis grinder kom nws du.
8.Tsev tu thiab kuaj tom qab kev teeb tsa:
o Ntxuav lub site, sim lub capacitance thiab tsis kam ntawm lub sensor dua, thiab ua pre-load xeem kom paub tseeb tias lub sensor ua hauj lwm zoo.
Lub Enviko 8311 sensor, nrog rau nws cov kev ua tau zoo, txhim khu kev qha raug, yooj yim installation, thiab ntau yam kev siv, yog ib qho kev xaiv zoo tshaj plaws rau kev saib xyuas thiab tswj cov kab ke. Nws cov qauv tsim tshwj xeeb thiab cov ntaub ntawv zoo ua kom muaj kev ruaj ntseg ntev. Txawm hais tias rau qhov hnyav hnyav, kev faib lub tsheb, lossis kev tshawb nrhiav nrawm, Enviko 8311 sensor muab cov ntaub ntawv meej, txhawb kev txhim kho cov tsheb thauj mus los ntse.
