Kev faib tawm thiab kev ua haujlwm ntawm cov khoom siv roj av

Cov khoom tseem ceeb ntawm lub ntsuas roj yog lub ntsuas roj. Gas sensors tuaj yeem muab faib ua peb pawg raws li lawv cov hauv paus ntsiab lus:

1. Gas sensors siv lub cev thiab tshuaj muaj zog, xws li semiconductors, catalytic combustion, khoom thermal conductivity, photoionization, thiab lwm yam.

2. Gas sensors siv lub cev muaj zog xws li thermal conductivity, optical cuam tshuam, infrared absorption, thiab lwm yam.

3. Gas sensors siv cov khoom siv hluav taws xob, xws li hom tam sim no, yam muaj peev xwm, thiab lwm yam.

Gas detectors ntsuas thiab qhia txog qhov concentration ntawm qee cov pa hauv huab cua los ntawm cov txheej txheem sib txawv. Gas detectors feem ntau yog cov khoom siv roj teeb uas siv rau kev nyab xeeb. Lawv raug tsim los ua cov khoom siv txav tau yooj yim lossis ruaj khov (kho), uas sawv cev rau cov pa roj ntau dhau los ntawm cov suab nrov lossis pom cov cim xws li lub tswb, teeb, lossis cov teeb liab sib txuas. Txawm hais tias muaj ntau yam khoom siv hluav taws xob niaj hnub qub tau tsim los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws muaj peev Qee lub tshuab ntes tuaj yeem siv los ua ib tus neeg los saib xyuas cov chaw ua haujlwm me me, lossis cov units tuaj yeem ua ke lossis sib txuas ua ke los tsim kev tiv thaiv.

Thaum lub ntsuas roj ntsuas cov roj concentration, cov lus teb sensor ua haujlwm raws li qhov taw qhia lossis ntsuas. Thaum cov lus teb ntawm lub sensor tshaj ib theem predetermined, lub tswb yuav qhib kom ceeb toom rau tus neeg siv. Feem ntau cov cuab yeej kuaj pom muaj tib txoj haujlwm: saib xyuas thiab ceeb toom ntawm qib roj txaus ntshai. Txawm li cas los xij, thaum xav txog hom kev ntsuas twg los nruab, nws yuav pab tau kom xav txog cov cuab yeej sib txawv.

Gas detectors rau cov khoom tshawb nrhiav sib txawv tuaj yeem muaj cov qauv kev tshawb nrhiav sib txawv, thiab cov khoom siv rau cov khoom ntsuas tib yam kuj tseem muaj cov qauv kev tshawb nrhiav sib txawv, xws li methane detectors, uas tuaj yeem ua rau catalytic combustion lossis infrared detection, nrog rau qhov sib txawv ntawm qhov raug thiab lifespan ntawm ob. .
