Chiyambi
Kusanthula kwachikhalidwe cha Chemical Oxygen Demand (COD) kumafuna zida za labotale, ma reagents oopsa (dichromate), ndi njira zazitali zogayira chakudya. Koma bwanji ngati mungathe kuyang'anira COD, Biochemical Oxygen Demand (BOD), Total Organic Carbon (TOC), ndi turbidity nthawi imodzi, nthawi yeniyeni, popanda ma reagents aliwonse?
Sensor ya Digital RS485 Output COD (Model CS6603CD) imapangitsa izi kukhala zotheka pogwiritsa ntchito ukadaulo wa Ultraviolet Absorption (UV254). Ma organic organic ambiri amayamwa kuwala kwa UV pa 254 nm. Poyesa kuyamwa kwa kuwala kwa mafunde awa, sensor imawerengera mosalekeza kuchuluka kwa COD, BOD, ndi TOC kofanana - zonsezi popanda mankhwala, kukonzekera zitsanzo, komanso kuipitsidwa.
Sensa iyi imaphatikizanso kulimbitsa kwa matope, pogwiritsa ntchito muyeso wosiyana kuti akonze kusokoneza kuchokera ku zinthu zolimba zomwe zapachikidwa, ndi burashi yodziyeretsa yokha kuti isawononge biofouling, ndikutsimikizira kuti ikugwira ntchito bwino kwa nthawi yayitali.
Masitepe Osavuta Ogwira Ntchito
Kugwiritsa ntchito sensa iyi n'kosavuta. Nayi njira yogwirira ntchito yachizolowezi:
Kukhazikitsa
- Ikani sensa molunjika kapena mopingasa mu selo yoyendera madzi, tsegulani njira, kapena ivikeni mwachindunji mu thanki pogwiritsa ntchito chogwirira choyenera.
- Lumikizani mawonekedwe a RS‑485 (Modbus) ku data logger yanu, PLC, kapena SCADA system. Kutalika kwa chingwe chokhazikika ndi mamita 10.
Mphamvu
- Perekani DC 12V (± 5%, mphamvu yamagetsi <50 mA yopanda chotsukira). Sensayi ili ndi IP68 rated, yoyenera kugwiritsidwa ntchito pansi pa madzi mpaka 1 bar pressure.
Kulinganiza
- Poyambitsa koyamba, chitani kuwerengera kwa ogwiritsa ntchito mfundo imodzi kapena ziwiri pogwiritsa ntchito njira yokhazikika (monga, KHP ya COD/BOD/TOC). Kuwerengera kosagwiritsa ntchito madzi opanda ayoni kumalimbikitsidwanso.
- Kuyesa kwa fakitale kwasungidwa kale; kusintha kwa magwiridwe antchito a ogwiritsa ntchito pa matrices enaake amadzi.
Yambani Kuyeza
- Sensa imatulutsa ma values a nthawi yeniyeni a COD, BOD, TOC, ndi turbidity kudzera mu Modbus RTU.
- Burashi yodziyeretsa yokha (yotsukira) imatha kuyatsidwa pamanja kapena yokha kuti iyeretse mawindo owoneka bwino, zomwe zimapangitsa kuti pakhale nthawi yokonza.
Kulemba ndi Kulamulira Deta
- Phatikizani deta ya digito mu makina anu odziyimira pawokha kuti muyambitse ma alarm, kusintha kuchuluka kwa mpweya, kapena kukonza kuchuluka kwa mankhwala mu njira zoyeretsera madzi akuda.
Mafotokozedwe Ofunika Mwachidule
| Chizindikiro | Malo ozungulira | Kulondola | Mawonekedwe |
|---|---|---|---|
| COD | 0.1 – 1500 mg/L (KHP) | <5% | 0.01 mg/L |
| BOD | 0.1 – 900 mg/L (KHP) | <5% | 0.01 mg/L |
| TOC | 0.1 – 750 mg/L (KHP) | <5% | 0.1 mg/L |
| Kugwedezeka | 0.1 – 4000 NTU | <3% kapena 0.2 NTU | 0.1 NTU |
| Kutentha | +5 – 45 °C | — | — |
N'chifukwa Chiyani Muyenera Kusankha Sensor Iyi?
- ✅Palibe ma reagents, palibe zinyalala, palibe kuipitsa
- ✅ Kutulutsa kwa COD, BOD, TOC, ndi turbidity nthawi imodzi
- ✅ Kubwezera kwa Turbidity chifukwa cha kulondola kwakukulu mu zitsanzo zenizeni
- ✅ Burashi yodziyeretsa yokha kuti isawonongeke kwambiri
- ✅ Digital RS‑485 Modbus kuti ikhale yosavuta kuphatikiza
- ✅IP68, yoyenera mikhalidwe yovuta yamunda
Mapeto
Kaya mukuyang'anira madzi amphamvu, otuluka, kapena okonzedwa m'fakitale ya boma kapena yamafakitale, sensa ya Digital RS485 Output COD imapereka njira ina yofulumira, yoyera, komanso yotsika mtengo m'malo mwa owunikira achikhalidwe a COD. Imapereka deta yokhazikika komanso yeniyeni yomwe imakuthandizani kuzindikira zochitika zodetsa msanga, kukonza njira zochizira, ndikuchepetsa ndalama zogwirira ntchito - zonsezi ndikuchotsa ma reagents oopsa.
