Chitsogozo Chomaliza Chosankhira Silicon Pressure Transmitter Yofalikira
Mwa mitundu yambiri ya ma transmitters - kuphatikiza ma ceramic, capacitive, ndi monocrystalline silicon masinthidwe - ma transmitters ophatikizika a silicon akhala njira yovomerezeka kwambiri pakuyezera mafakitale.
Kuchokera kumafuta & gasi kupita ku kukonza mankhwala, kupanga zitsulo, kupanga magetsi, ndi uinjiniya wa chilengedwe, ma transmitterswa amapereka kuwunika kodalirika komanso kolondola kwa kuthamanga kwa gauge, kukakamizidwa kwathunthu, komanso kugwiritsa ntchito vacuum.
Kodi Diffused Silicon Pressure Transmitter Ndi Chiyani?
Ukadaulowu udayamba chapakati pa 1990s pomwe NovaSensor (USA) idachita upainiya ma diaphragms a silicon opangidwa ndi makina ang'onoang'ono omangidwa ndi galasi. Kupambanaku kudapanga masensa owoneka bwino, olondola kwambiri okhala ndi kubwereza kwapadera komanso kukana dzimbiri.
Mfundo Yoyendetsera Ntchito
- Kuthamanga kwa ndondomeko kumadutsa kudzera pa diaphragm yodzipatula ndi mafuta a silikoni kupita ku silicon diaphragm
- Mphamvu yolozera (yozungulira kapena vacuum) imagwira mbali ina
- Kupatuka kotsatira kumazindikiridwa ndi mlatho wa Wheatstone wa ma strain gauges, kutembenuza kuthamanga kukhala chizindikiro chamagetsi.
8 Zofunikira Zosankha
1. Kuyezedwa Kwapakatikati Kugwirizana
Zopangira sensa ziyenera kufanana ndi mankhwala ndi mawonekedwe amadzimadzi anu:
- Mapangidwe okhazikika amagwiritsa ntchito ma diaphragms achitsulo chosapanga dzimbiri 316L pazinthu zambiri
- Pazinthu zamadzimadzi zowononga kapena zonyezimira, tchulani zotumizira ma diaphragm
- Zosankha zamagulu azakudya zomwe zimapezeka pazamankhwala ndi zakumwa
- Makanema owoneka bwino kwambiri (otayirira, matope, phula) amafunikira mapangidwe a diaphragm opanda pabowo.
2. Pressure Range Selection
Mitundu yomwe ilipo kuyambira -0.1 MPa mpaka 60 MPa. Nthawi zonse sankhani kuchuluka kwa 20-30% kuposa kuthamanga kwanu kokwanira kuti mupewe kulemetsa.
Pressure Unit Conversion Guide
| Chigawo | Mtengo Wofanana |
|---|---|
| 1 MPpa | 10 bar / 1000 kPa / 145 psi |
| 1 bwalo | 14.5 psi / 100 kPa / 750 mmHg |
Gauge vs. Absolute Pressure:Kuthamanga kwa gauge ndi mphamvu yozungulira (ziro ikufanana ndi mlengalenga), pomwe mafotokozedwe amphamvu kwambiri amasiya. Pazogwiritsa ntchito pamalo okwera, gwiritsani ntchito masensa ojambulira mpweya kuti mulipirire kusintha kwa mumlengalenga.
Mfundo Zapadera Zogwiritsira Ntchito
Kuyeza kwa Gasi la Ammonia
Tchulani ma diaphragm okhala ndi golide kapena zokutira zapadera za anti-corrosive kuti mupewe kuwonongeka kwa sensa mu ntchito ya ammonia. Onetsetsani kuti nyumba yotumizira ma transmitter ikukwaniritsa mavoti a NEMA 4X kapena IP66 pakuyika panja.
Kuyika kwa Malo Owopsa
Kwa malo oyaka kapena ophulika:
- Pemphani mafuta a fluorinated (FC-40) m'malo modzaza mafuta a silicone
- Tsimikizirani ziphaso zotetezedwa mwakuthupi (Ex ia) kapena zosayaka (Ex d)
- Onetsetsani kukhazikitsa koyenera ndi zotchinga pamiyezo ya IEC 60079
Mapeto
Ma transmitters ophatikizika a silicon amapereka kusinthasintha koyenera, kulimba, komanso kusinthasintha pamachitidwe am'mafakitale. Kusankha koyenera-kuchokera pakuwunika kogwirizana ndi media kupita kumayendedwe amawu - kumatsimikizira kulondola kwa kuyeza komanso kudalirika kwanthawi yayitali.
Kaya kuyang'anira mizere ya nthunzi yothamanga kwambiri, kuwongolera momwe mankhwala amagwirira ntchito, kapena kuwonetsetsa kuti ammonia akugwira bwino, kasinthidwe koyenera ka transmitter kumapangitsa kuti magwiridwe antchito azikhala bwino komanso chitetezo chamagwiritsidwe ntchito.
