1. Cov lus qhia luv luv.

LEL detector ntsuas cov qib txaus ntshai ntawm tag nrho cov roj hluav taws xob hauv huab cua, qhia hauv feem pua qis qhov txwv tsis pub, peb hu nws EX gas detector thiab. Lub LEL gas detector ua haujlwm ntawm lub hauv paus ntsiab lus ntawm catalytic combustion. Qhov no sensor ntes cov concentration ntawm combustible gas los ntawm combustion cov tshuaj tiv thaiv. Nws muaj cov cua kub platinum tsis kam xaim ua cov cua sov. Thaum cov roj combustible hu rau cov hlau tsis kam thiab yog rhuab, lub tshav kub generated thaum lub sij hawm combustion txheej txheem yuav cuam tshuam tus nqi kuj hloov pauv ntawm cov hlau tsis kam, yog li ntsuas qhov concentration ntawm cov roj. Thaum cov hlau tsis muaj zog tas lawm, yuav tsum tau hloov lub len sensor tshiab.

Lub LEL (Lower Explosive Limit) gas detector yog ib qho cuab yeej tshwj xeeb rau kev kuaj xyuas qhov qis qis qis qis ntawm cov pa hluav taws xob thiab tau siv dav hauv kev saib xyuas kev nyab xeeb hauv kev lag luam xws li petrochemicals, thee mines thiab roj.

2. Cov yam ntxwv.

(1) Catalytic LEL sensor, siab raug thiab rhiab heev.

(2). Saib xyuas tag nrho EX roj concentration ua ke

(3) Cov ntaub ntawv pov thawj tawg, pov thawj qib ExibII CT6, IP65 dej plua plav pov thawj.

(4) Nyeem cov nqi roj, cov ntaub ntawv ceeb toom, lub sij hawm ntawm LCD vaj huam sib luag, yooj yim rau calibration

(5) Nrog xoom calibration muaj nuj nqi, ua kom pom tseeb dua thiab txhim khu kev qha.

(6.4-20mA teeb liab tso zis, tau tshaj PLC.

(7) Infrared chaw taws teeb tswj, tsis tas yuav qhib lub plhaub kom ua haujlwm.

4.Qhov tawg txwv ntau ntawm cov roj sib txawv:

Thaum combustible gas, vapor ntawm combustible kua (los yog combustible plua plav) sib tov nrog huab cua thiab mus txog ib tug tej yam concentration, nws yuav tawg thaum nws ntsib qhov hluav taws kub. Qhov no concentration ntau yam uas yuav tshwm sim tshwm sim yog hu ua qhov tawg txwv, uas feem ntau yog qhia raws li qhov ntim feem pua ntawm combustible gas, vapor los yog hmoov av nyob rau hauv cov huab cua. Nyob rau hauv qhov "explosion concentration range", qhov tsawg kawg nkaus tawg theem peb hu nws qhov qis tawg txwv; thiab qhov siab tshaj plaws tawg lel peb hu nws lub siab tawg txwv. Tsuas yog nyob nruab nrab ntawm ob qhov kev sib xyaw no tsuas yog muaj kev pheej hmoo ntawm kev tawg.Qhov kev txwv tawg ntawm cov pa roj sib txawv yog hais txog cov concentration txwv ntawm qhov kev tawg yuav tshwm sim thaum cov roj combustible nce mus txog qee qhov concentration hauv huab cua. Piv txwv li, qhov kev txwv kev tawg ntawm hydrogen yog qhov dav thiab qhov txaus ntshai heev. ua

methane (natural gas): 5.0% - 15.0%.

Hydrogen: 4.0% - 75.0%.

Cov pa roj carbon monoxide: 12.5% - 74.2%.

Acetylene: 2.3% - 100%.

Roj av: 1.0% - 6.0%.

Ethanol (cawv): 3.0% - 19.0%.

Propane: 2.1% - 9.5%.

Ethane: 3.0% - 12.4%

5. Kev tu

(1) Ua kom ntseeg tau tias lub ntsuas LEL qhia xoom hauv ib puag ncig yam tsis muaj lub hom phiaj roj

(2) Siv cov roj calibration ntawm tus qauv concentration los calibrate ib xyoos ib zaug.

(3).Sensor lifespan (feem ntau yog 2 mus rau 3 xyoos), hloov nyob rau hauv lub sij hawm
