Lub hauv paus ntsiab lus thiab kev pab cuam lub neej ntawm Combustible Gas Detector Sensors
1, Lub neej kev pab cuam ntawm combustible gas detectors yog peb xyoos, vim tam sim no, ib co combustible gas detectors muaj sensors uas ntes catalytic combustion. Lub neej kev pab cuam ntawm xws li sensors yog peb xyoos, thiab nws yog pom zoo kom hloov lawv tom qab peb xyoos.
Kev tawg pov thawj casing, ruaj khov thiab ruaj khov;
Kev ntseeg siab thiab raug, zoo tiv thaiv - muaj peev xwm cuam tshuam;
Kev ua tau zoo tus nqi piv.
2, Catalytic combustion gas sensor
Hom sensor no yog npaj nrog lub siab - kub resistant catalyst txheej ntawm lub platinum resistor. Ntawm qhov kub thiab txias, combustible gases catalyze combustion ntawm nws nto. combustion yog ib qho kev ua haujlwm ntawm cov concentration ntawm cov roj combustible raws li qhov kub thiab txias ntawm platinum resistor nce thiab qhov kev hloov pauv.
Catalytic combustion gas sensors xaiv ntes cov pa hluav taws xob: txhua yam uas tuaj yeem hlawv tuaj yeem kuaj pom; Txhua yam uas tsis tuaj yeem hlawv tsis muaj lus teb los ntawm lub sensor. Tau kawg, muaj ntau qhov kev zam rau nqe lus 'txhua yam uas tuaj yeem hlawv tuaj yeem kuaj tau', tab sis tag nrho, cov kev xaiv saum toj no siv tau.
Catalytic combustion gas sensors muaj qhov ntsuas qhov tseeb, teb ceev ceev, thiab lub neej ntev. Cov zis ntawm cov sensors yog ncaj qha ntsig txog kev tawg ntawm ib puag ncig thiab yog hom tseem ceeb ntawm sensors hauv kev tshawb nrhiav kev nyab xeeb.
Disadvantage: Tsis muaj selectivity nyob rau hauv lub flammable roj ntau yam. Ua haujlwm hauv qhov chaw tsaus ntuj ua rau muaj kev pheej hmoo ntawm hluav taws kub thiab tawg. Feem ntau cov organic vapors muaj cov tshuaj lom rau cov sensors.
Tam sim no, cov chaw muag khoom tseem ceeb ntawm hom sensor no yog nyob rau hauv Suav teb, Nyiv, thiab United Kingdom (lub teb chaws ntawm invention)! Tam sim no, Tuam Tshoj yog cov neeg siv ntau tshaj plaws ntawm hom sensor (thee mine) thiab tseem muaj cov cuab yeej zoo tshaj plaws sensor ntau lawm. Txawm hais tias ntau tus neeg sawv cev lossi cuam tshuam nrog zej zog txoj kev nkag siab ntawm qhov ntsuas no hauv lawv txoj kev nce qib, tom qab tag nrho, cov tuam txhab tseem ceeb ntawm catalytic combustion gas sensors nyob hauv Suav teb.
Daim ntawv thov thaj chaw: hluav taws xob, roj av, petrochemical, tshuaj lom neeg, metallurgical, fais fab, chav boiler, tsev so thiab tsev noj mov, nrog rau ntau yam kev lag luam thiab pej xeem ib puag ncig.
Nrog rau kev nce qib ntawm kev siv thev naus laus zis, cov nplai hluav taws xob ua los ntawm cov ntsuas qhov hnyav tau siv dav hauv ntau qhov kev lag luam, ua tiav cov khoom hnyav thiab raug. Tshwj xeeb tshaj yog nrog qhov tshwm sim ntawm microprocessors thiab kev txhim kho tas mus li ntawm cov txheej txheem kev lag luam automation, qhov hnyav sensors tau dhau los ua cov cuab yeej tsim nyog hauv kev tswj cov txheej txheem. Los ntawm kev ntsuas qhov hnyav ntawm cov tso tsheb hlau luam loj, hoppers, crane scale, tsheb teev, thiab lwm yam uas tsis tuaj yeem ntsuas tau yav dhau los, mus rau kev tshawb nrhiav tsis siv neeg thiab cov hmoov pub mis tswj hauv batching systems rau kev sib xyaw thiab faib ntau yam khoom siv raw, cov txheej txheem ntau lawm, thiab lwm yam., cov ntsuas ntsuas tau raug siv. Tam sim no, qhov hnyav sensors yuav luag siv nyob rau hauv txhua qhov hnyav.
