Online Inductive Digital Acid Alkaline Concentration Sensor

Mawu Oyamba

Digital conductivity sensor ili ndi ntchito zonse zoyezera ndi kuwerengera madulidwe ndi mchere wosiyanasiyana,kuchuluka kwa asidi ndi alkali.Imagonjetsa ambiri

zovuta zakalemasensa ndi kuphatikiza chizindikirokukonza dera mu MCU ASIC yophatikizidwa, yomwe imathandizira sensa kuti iwunikire kale

kuchoka kufakitale, ndipo mtengo wa calibration ndi wokhazikikazosungidwa mu probe.Ndi ntchito yolipirira kutentha,kutentha kumakhalanso mwachindunji digito linanena bungwe.

Mawonekedwe

1. Kugwira ntchito m'malo ovuta kwambiri ndiabwino kwambiri, osamva mankhwala opangidwa ndielectrode si kusokoneza polarized, kupewa dothi,

zonyansa komanso ngakhale kukhudzafouling wosanjikiza kuphimba zochitika ngatimonga osauka kwambiri, yosavuta ndi yosavuta kukhazikitsa kotero ndi osiyanasiyana kwambiri ntchito.Ma electrode opanga

kugwiritsidwa ntchito kwapamwambandende ya zidulo(monga fuming sulfuric acid) chilengedwe.

2. English acid ndende mita ntchito, kulondola mkulu, ndi mkulu bata.

3. Ukadaulo wa sensa ya conductivity umachotsa zolakwika zotsekera ndi polarization.Amagwiritsidwa ntchito m'magawo onse olumikizanama electrode amatha kuyambitsa kutsekeka komwe kumakhala ndi kuchuluka

ntchito.

4. Sensa yaikulu yotsegula, kukhazikika kwa nthawi yaitali.

5. Khazikitsani mabakiteriya osiyanasiyana ndikugwiritsa ntchito dongosolo lokhazikika la bulkhead, kukhazikitsa kosinthika.
