Quartz Sensor Test ua ntej kev teeb tsa hauv Weigh-In-Motion

Weigh-In-Motion (WIM) yog ib qho cuab yeej uas ntsuas qhov hnyav ntawm lub tsheb thaum lawv txav mus los, tshem tawm qhov xav tau tsheb nres. Nws siv cov sensors ntsia hauv qab ntawm txoj kev los xyuas qhov kev hloov siab thaum lub tsheb hla dhau lawv, muab cov ntaub ntawv ntawm lub sijhawm ntawm qhov hnyav, qag load, thiab ceev. WIM cov tshuab tau siv dav hauv kev tswj hwm tsheb, kev tswj xyuas ntau dhau, thiab kev thauj mus los txhawm rau txhim kho kev ua haujlwm thiab kev nyab xeeb.

WIM muab cov txiaj ntsig tseem ceeb, suav nrog kev txo qis kev cuam tshuam, kev saib xyuas lub sijhawm tiag tiag, thiab txhim kho kev nyab xeeb los ntawm kev txheeb xyuas cov tsheb thauj khoom ntau dhau. Ntawm ntau hom sensors, quartz sensors tshwj xeeb tshaj yog haum rau High-Speed ​​Weigh-In-Motion (HSWIM) vim lawv qhov raug siab, ua haujlwm ntev, thiab muaj peev xwm tiv taus ib puag ncig hnyav. Quartz sensors, xws li CET8312-A, muab kev ua tau zoo ib yam txawm tias nyob rau hauv kev kub ceev, ua rau lawv zoo tagnrho rau cov ntawv thov uas yuav tsum tau ntsuas qhov hnyav thiab txhim khu kev qha hauv cov xwm txheej ceev ceev.

Cov hauv qab no qhia txog ob txoj kev sim tseem ceeb uas yuav tsum tau ua ua ntej txhim kho Quartz Sensor: Kev Ntsuas Hluav Taws Xob thiab Waveform Test.

1. Rwb thaiv tsev Test Method

1) Ntxig sensor Q9 taub hau rau hauv megohmmeter qhov (socket).

2) Teem megohmmeter mus rau 1000V txoj haujlwm (txwv tsis pub siv 2500V txoj haujlwm)

3) Tig thiab nias lub ntsuas ntsuas ntsuas lub moos, hnov ​​lub suab "beep", lub teeb liab liab nyob rau sab xis sab xis illuminates pib kuaj, lub sijhawm sim yuav tsum tsis pub tsawg dua 5 vib nas this

1) Cov qhabnias xeem raws li qhia:

Cov txiaj ntsig pom OL chav tsev (GΩ): Kev ua tau zoo tshaj plaws

Cov txiaj ntsig pom 163 units (MΩ): Siv tsis tau

CEEB TOOM!!! Tom qab kuaj cov sensors nrog megohmmeter, sensors khaws cov hluav taws xob ntau ntau. Sensors yuav tsum tau luv luv-circuited tso tawm lub zog cia. Kev sib txuas rau cov ntaub ntawv tau los yog cov khoom hnyav uas tsis muaj qhov tso tawm tom qab kev ntsuas rwb thaiv tsev yuav rhuav tshem cov khoom siv hluav taws xob siab, ua rau nws siv tsis tau.

1.Waveform Test Method

1) Ntxig sensor Q9 lub taub hau rau hauv oscilloscope "CH1" qhov (socket), kho lub sij hawm mus rau 200ms thiab voltage mus rau 500mv, los yog kho raws li qhov chaw.

2) Strike sensor ntawm txhua qhov chaw nrog roj hmab rauj, oscilloscope yuav tsum pom cov teeb liab waveform tso zis

Tsis muaj teeb liab tso zis raws li qhia saum toj no

1.Sensor Kev Ntsuas Zoo

Insulation Assessment Standards:

• OL unit GΩ: Kev ua tau zoo tshaj plaws
• Ntau tshaj 10 GΩ: Zoo heev
• Tsawg dua 1 GΩ: Siv tau
• 300MΩ thiab hauv qab no: Tsis Zoo (Khoom)
