Cov tub ntxhais hluas lub sensors ntawm cov roj detectors cais yog li cas?
Cov ntaub pua chaw kuaj tau siv dav hauv cov chaw tsim khoom, cov nroj tsuag muaj kev muaj zog, thiab cov chaw nrog cov kuab paug nyob hauv lub neej txhua hnub. Cov tub ntxhais tseem ceeb ntawm cov roj detectors yog cov roj teeb. Yog li, dab tsi yog kev faib tawm ntawm cov kev sib txuas ntawm cov roj sensors?
2. Electrochnical roj sensor
Electrochemical roj sensors zoo li lub npe, lawv ntsuas cov pa roj los ntawm kev sim cov tam sim no. Qhov zoo ntawm electrochemical gas rhiab thiab xaiv tau siab ntawm gases, tab sis qhov tsis zoo yog tias lawv lub neej pabcuam feem ntau nyob ib ncig ntawm ob xyoos.
3. Catalytic Kev Sib Tw Roj Sensor
Kev sib txuas cov roj teeb tsis yog qhov tsis sib xws rau cov roj uas tsis sib xws, yog li lawv daim ntawv thov kev thov tseem ceeb yog txhawm rau tshawb xyuas cov roj sib txuas. Yog li ntawd, lawv feem ntau siv los saib xyuas cov roj txuas nrog roj av thiab petrochemical, cov tuam txhab tshuaj lom neeg, thiab lwm yam lag luam. Nws lub hauv paus ntsiab lus ua haujlwm yog tias cov khoom siv rhiab loj hlawv raws li kev nqis hluav taws xob, thiab kev sib tw tau cuam tshuam los ntawm catalyst. Lub tshuab hluav taws xob hluav taws xob cua sov tsim hluav taws xob ntau dua rau cov kev sib txuas, yog li hloov nws tus nqi tiv thaiv.
4. Optical Gas Sensor
Phosgene sensors tsuas yog suav hom kev nqus tau ntau yam, hom kev nqus dej, thiab lwm yam, feem ntau, feem ntau yog suav nrog kev nqus khoom. Ntsuas lub wavelength infrared wavelength tuaj yeem kuaj cov roj, raws li cov roj sib txawv muaj sib txawv ntawm cov av tsis sib haum. Tam sim no, vim nws cov kev sib txuas lus sib txuas, tus nqi feem ntau yog qhov tseem ceeb heev.
5. Khoom hauv lub xeev electrolyte roj sensor
Cov khoom siv hluav taws xob yog ib hom roj teeb hluav taws xob uas siv cov khoom siv tau zoo li cov electrolyte. Nws nyob ntawm semiconductors thiab ultrasonicememistry. Xaiv thiab rhiab siab dua yog siab dua tshaj li cov semiconductors, thiab lub neej ntev ntev dua electrochemistry, yog li nws tau thov hauv ntau yam. Qhov tsis zoo yog tias lub sijhawm teb yog ntev.
