Umhlahlandlela Wokugcina Wokukhetha I-Silicon Pressure Transmitter Esabalalisiwe
Phakathi kwezinhlobo eziningi zokudlulisa ingcindezi—okuhlanganisa nokuhlukahluka kwe-ceramic, capacitive, kanye ne-monocrystalline silicon—ama-silicon pressure pressure transmitter asabalele abe yisixazululo esamukelwa kabanzi sokusetshenziswa kokulinganisa kwezimboni.
Ukusuka kuwoyela negesi kuye ekucutshungulweni kwamakhemikhali, ukukhiqizwa kwensimbi, ukukhiqiza amandla, nobunjiniyela bemvelo, lezi zithumeli ziletha ukuqapha kwengcindezi okuthembekile nokunembile kuyo yonke ingcindezi yegeji, ukucindezela okuphelele, kanye nezicelo ze-vacuum.
Iyini I-Diffused Silicon Pressure Transmitter?
Ubuchwepheshe baqala maphakathi nawo-1990s lapho i-NovaSensor (USA) iphayona ama-diaphragm e-silicon enziwe ngomshini omncane ahlanganiswe nengilazi. Lokhu kuphumelela kudale izinzwa ezihlangene, ezinembe kakhulu ezinokuphinda okukhethekile kanye nokumelana nokugqwala.
Isimiso sokusebenza
- Ingcindezi yenqubo idlulisa nge-diaphragm ehlukanisayo namafutha e-silicone iye ku-silicon diaphragm
- Ingcindezi yesithenjwa (i-ambient noma i-vacuum) isebenza ngakolunye uhlangothi
- Ukuchezuka okuwumphumela kutholwa ibhuloho le-Wheatstone lamageji obunzima, eliguqula ingcindezi ibe isignali kagesi.
8 Imibandela Yokukhetha Ebalulekile
1. Ukuhambisana Okulinganiselwe Okumaphakathi
I-sensor material kufanele ihambisane nezakhi zamakhemikhali nezomzimba zoketshezi lwakho lwenqubo:
- Imiklamo ejwayelekile isebenzisa amadiaphragm ensimbi engagqwali angu-316L ezinhlelweni eziningi
- Ngoketshezi olubolayo noma olucwebezelayo, cacisa ama-diaphragm transmitters ashaywayo
- Izinketho zebanga lokudla ezitholakalayo kwezicelo zemithi neziphuzo
- Imidiya ye-viscosity ephezulu (i-slurry, udaka, itiyela) idinga imiklamo ye-diaphragm eshaywayo engenazimbobo
2. Ukukhethwa Kwebanga Lokucindezela
Ububanzi obutholakalayo busukela ku -0.1 MPa ukuya ku-60 MPa. Ngaso sonke isikhathi khetha ububanzi obungu-20-30% obungaphezu kokucindezela kwakho okuphezulu kokusebenza ukuze uvimbele ukulayishwa ngokweqile.
I-Pressure Unit Conversion Guide
| Iyunithi | Inani Elilinganayo |
|---|---|
| 1 MPa | I-10 bar / 1000 kPa / 145 psi |
| 1 ibha | 14.5 psi / 100 kPa / 750 mmHg |
I-Gauge vs. Absolute Pressure:Izinkomba zengcindezi yegeyiji ingcindezi ye-ambient (zero ilingana nomkhathi), kuyilapho izithenjwa zengcindezi ephelele zingenasici. Kuzinhlelo zokusebenza zokuphakama okuphezulu, sebenzisa izinzwa zegeji yokungena umoya ukuze unxephezele ukuhlukahluka kwendawo komkhathi.
Ukucatshangelwa Kwesicelo Esikhethekile
Ukukala Igesi ye-Amonia
Cacisa ama-diaphragm agqitshwe ngegolide noma izimbotshana ezikhethekile zokunqanda ukubola ukuze kuvinjelwe ukuwohloka kwenzwa kusevisi ye-ammonia. Qinisekisa ukuthi indlu yomthumeli ihlangabezana nezilinganiso ze-NEMA 4X noma ze-IP66 zokufakwa kwangaphandle.
Ukufakwa Kwendawo Eyingozi
Ngezindawo ezivuthayo noma eziqhumayo:
- Cela uwoyela we-fluorinated (FC-40) esikhundleni sokugcwalisa uwoyela we-silicone ojwayelekile
- Qinisekisa izitifiketi zezinhlelo zokusebenza eziphephile ngaphakathi (Ex ia) noma ezingashi (Ex d)
- Qinisekisa ukufakwa kwesisekelo esifanele kanye nezithiyo ngamazinga e-IEC 60079
Isiphetho
Izidluliseli zomfutho we-silicon ezisabalalisiwe zinikeza ibhalansi efanele yokunemba, ukuqina, kanye nokuguquguquka kuzo zonke izinqubo zezimboni. Ukukhetha okufanele—kusukela ekuhloleni ukuhambisana kwemidiya kuya ekucacisweni kwesignali ephumayo—kuqinisekisa kokubili ukunemba kokulinganisa nokwethembeka kwesikhathi eside.
Ukuthi uqapha imigqa yesitimu esinomfutho ophezulu, ukulawula ukusebenza kwamakhemikhali, noma ukuqinisekisa ukuphatha okuphephile kwe-ammonia, ukumiswa kwesidlulisi esilungile kuthuthukisa kokubili ukusebenza kahle kwenqubo nokuphepha kokusebenza.
