Standard automotive sensors ib txwm ua tsis tau thaum raug kev poob siab, kev co, thiab cov dej tsis zoo ntawm cov tsheb khiav tawm (OHV). Cov neeg caij tsheb-qib Cheebtsam tsuas yog tsis tuaj yeem tswj hwm qhov tseeb ntawm kev ua haujlwm hnyav. Lub sijhawm tsis tau npaj tseg hauv kev tsim kho, mining, lossis tshuab ua liaj ua teb ncaj qha cuam tshuam rau qhov project profitability. Kev nyeem ntawv tsis tseeb thiab kev poob siab sai sai ua rau cov nqi qeeb no. Koj tsis tuaj yeem them cov khoom siv stalling hauv thaj teb vim tias cov khoom siv yooj yim snapped hauv chassis flex.
Qhia txog txoj cai Automotive Level Sensor
Ntsiab Cai
Off-road machinery yuav tsum tau tshwj xeeb theem sensors ua rau kev sib txuas ntau-axis kev co thiab huab cua kub gradients.
Kev xaiv tshuab (capacitive vs. magnetic reed vs. ultrasonic) yuav tsum tau hais los ntawm cov kua dej dielectric zog, viscosity, thiab tank geometry.
Standardized mounting, xws li SAE-5 Bolts Level Sensor qauv, accelerates kev koom ua ke thiab txo cov nqi tu mus sij hawm ntev.
Kev ntsuas qhov Off-Road Level Sensor yuav tsum ntsuas qhov kev daws teeb meem siab nrog cov khoom siv ua haujlwm kom tiv thaiv lub tswb tsis tseeb tshwm sim los ntawm cov kua dej slosh.
Lub Hnyav Reality ntawm Off-Road Environments vs. Standard Automotive
Cov tsheb neeg caij tsheb ua haujlwm ntawm qhov sib luag, uas tuaj yeem ua tiav. Mobile machinery ntsib qhov sib txawv ntawm lub cev xav tau. Cov tsheb laij teb, excavators, thiab cov tsheb thauj khoom uas muaj kev sib tw ua rau muaj kev vibrations qis qis thaum lub sijhawm ua haujlwm. Lawv kuj muaj kev cuam tshuam loj-G poob siab tam sim ntawd. Ib lub thoob tawm tsam cov khoom hauv txaj xa tawm lub zog kinetic hnyav los ntawm tag nrho cov chassis. Tus qauv ntsuas yuav ua rau qaug zog sai thiab tawg nyob rau hauv cov khoom siv rov ua dua tshiab.
Ntoj inclines thiab erratic txav ua aggressive kua sloshing nyob rau hauv lub tso tsheb hlau luam. Qhov turbulence no yooj yim ua rau lub tswb qis qis. Lub tsheb laij teb ua haujlwm ntawm 30-degree toj roob hauv pes hloov ntau pua nkas loos dej tam sim. Txhawm rau tiv thaiv kev nyeem ntawv tsis raug, cov kws ua haujlwm siv tshuab baffles. Tso cov qhov dej tseem nyob ib ncig ntawm qhov ntsuas qhov ntsuas lub cev txwv tsis pub cov dej ntws tawm. Electronic dampening muab ib qho ntxiv software-raws li ncua. Nws nruab nrab lub teeb liab tso zis ntau dua ob peb feeb. Qhov no ob txoj hauv kev ua kom lub dashboard nyeem ntawv tseem nyob ruaj khov nyob rau thaj chaw ntxhib.
