Lub neej ntev ntawm intrinsically nyab xeeb ceev sensors feem ntau yog nyob ntawm 2 mus rau 10 xyoo, nyob ntawm seb yam xws li hom sensor, kev khiav hauj lwm ib puag ncig, kev siv zaus, thiab tu.
Lub log ceev sensors: Cov pa roj carbon monoxide thiab cov khoom siv hluav taws xob zoo ib yam muaj lub neej ntev li ntawm 2 mus rau 3 xyoos, thaum lub ntsuas hluav taws xob infrared tuaj yeem kav li 3 txog 5 xyoos.
Hall effect speed sensors: Raws li cov khoom siv hauv xeev- cov khoom siv hauv xeev uas tsis muaj qhov txav mus los, lawv txoj kev xav muaj lub neej ntev dua. Raws li ib txwm muaj, cov khoom zoo siab - tuaj yeem ua haujlwm tau ntau txhiab mus rau ntau pua txhiab teev (kwv yees li 5 txog 10 xyoo).
Mining-cov qauv tshwj xeeb (piv txwv li, GSC6): Siv lub siab- kev ruaj ntseg tsim, cov no tsim nyog rau qhov chaw hnyav xws li cov mines thee thiab tuaj yeem tshaj 5 xyoo hauv kev siv tiag.
Cov yam tseem ceeb uas cuam tshuam rau lub neej muaj xws li:
Ib puag ncig tej yam kev mob: Kub kub, high humidity, muaj zog magnetic teb, thiab plua plav ua rau aging.
Kev Ua Haujlwm: Ntev ntev - kev ua haujlwm zaus lossis siv ntau dhau ua rau lub neej luv.
Kev Kho: Kev kuaj xyuas cov teeb liab tawm tsis tu ncua, ntxuav qhov chaw hnov qhov chaw, thiab ua kom nruj rau cov qauv mounting pab kom ntev lub neej.
Txhawm rau kom muaj kev nyab xeeb ntawm lub cev, nws raug nquahu kom ua qhov kev tshuaj xyuas tsis tu ncua thiab kev tiv thaiv kev hloov pauv raws li cov khoom siv kev ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej tseem ceeb xws li cov mines thiab cov khoom siv thauj khoom, kom tsis txhob muaj kev nyab xeeb tshwm sim los ntawm qhov tsis ua haujlwm sensor.
