Dab tsi yog T90/T50 teb lub sij hawm nyob rau hauv cov roj detectors
Txawm hais tias lub hom phiaj ntawm lub tshuab ntsuas roj, txawm tias nws yog lub tshuab hluav taws xob hauv tsev lossis lub npe txawv teb chaws loj, peb tuaj yeem pom T90 lossis T50 lub sijhawm teb nyob rau hauv qhov ntsuas ntsuas. Nws yog ib qho tseem ceeb heev, tab sis nws txhais li cas tiag?
Qhov tseeb, ntxiv rau cov sij hawm teb T90 thiab T50, kuj tseem muaj tsawg dua T10 thiab T20 lub sij hawm teb. Tab sis kev xav, lawv txhua tus txhais tau tib yam, xav txog cov lus teb ceev ntawm cov khoom siv roj rau cov pa phem thiab cov pa phem.
Feem ntau, T50/T90 lub sij hawm teb yog hais txog lub sij hawm nws yuav siv sij hawm rau ib tug gas detector hloov los ntawm kev nyeem ntawv 0 mus rau 50 feem pua los yog 90 feem pua ntawm cov concentration ntawm cov pa phem ntsuas nyob rau hauv ib puag ncig. . Piv txwv li, rau lub ntsuas hydrogen peroxide, nws lub sijhawm teb T90 tsawg dua lossis sib npaug li 60 vib nas this. Nws txhais tau hais tias lub sijhawm xav tau rau lub tshuab kuaj xyuas hydrogen peroxide hloov los ntawm kev nyeem 0 mus rau 90 feem pua ntawm qhov tseeb hydrogen peroxide concentration hauv ib puag ncig.
Piv txwv li, yog tias qhov concentration ntawm hydrogen peroxide nyob rau hauv ib puag ncig tiag tiag yog 5ppm, tom qab ntawd tsawg dua 60 vib nas this, qhov kev nyeem ntawv ntawm tus ntes yuav hloov mus rau 4.5ppm; Yog tias qhov concentration ntawm hydrogen peroxide nyob rau hauv ib puag ncig yog 20ppm, tom qab ntawd tsawg dua 60 vib nas this, qhov kev nyeem ntawv ntawm tus ntes yuav hloov mus rau 18ppm.
Yog li ntawd, peb tuaj yeem paub tias lub sijhawm T50 / T90 lub sijhawm teb luv dua, qhov ntsuas roj ntau dua nws tus kheej. Qhov no yog vim li cas T50 / T90 yog ib qho tseem ceeb heev sensor parameter rau roj sensors. Yog tias qee lub npe tsis tuaj yeem muab T50 / T90 sensor tsis tau, nws yuav tsum ua tib zoo xyuas seb qhov kev ua haujlwm ntawm lub sensor nws tus kheej puas zoo lossis tsis zoo.
