Chitsogozo Chachikulu Chosankha Silicon Pressure Transmitter Yofalikira
Chitsogozo cha akatswiri pakugwiritsa ntchito kuyeza kwa mafakitale
Mwachidule
Ma transmitters amasiyanitsidwa ndi matekinoloje awo ozindikira, kuphatikiza silicon, ceramic, capacitive, ndi monocrystalline silicon. Mwa izi, ma transmitters ophatikizika a silicon ndi omwe amatengedwa kwambiri m'mafakitale onse. Odziwika chifukwa cha ntchito zawo zolimba, zodalirika, komanso zotsika mtengo, ndizoyenera kuyang'anira kupanikizika ndi kulamulira mu mafuta ndi gasi, kukonza mankhwala, kupanga zitsulo, kupanga magetsi, zomangamanga, ndi zina.
Ma transmitterswa amathandizira kuyeza kwa gauge, kotheratu, komanso kukakamiza kolakwika, ngakhale m'malo owononga, amphamvu kwambiri, kapena pamalo owopsa.
Koma kodi luso limeneli linayamba bwanji, ndipo ndi zinthu ziti zimene muyenera kuziganizira posankha chitsanzo chabwino?
Chiyambi cha Diffused Silicon Technology
M'zaka za m'ma 1990, NovaSensor (USA) adayambitsa m'badwo watsopano wa masensa a silicon omwe amagwiritsidwa ntchito pogwiritsa ntchito matekinoloje apamwamba a micromachining ndi silicon bonding.
Mfundoyi ndi yosavuta koma yothandiza: kupanikizika kwa ndondomeko kumasiyanitsidwa ndi diaphragm ndikusamutsidwa kupyolera mu mafuta osindikizidwa a silicone kupita ku nembanemba ya silicon. Kumbali inayi, kuthamanga kwa mumlengalenga kumagwiritsidwa ntchito ngati chidziwitso. Kusiyana kumeneku kumapangitsa kuti nembanemba ikhale yopunduka—mbali imodzi imatambasuka, ina imakanika. Ma geji ophatikizika amazindikira kusinthaku, ndikusandulika kukhala chizindikiro chamagetsi.
8 Zofunikira Zosankha Posankha Silicon Pressure Transmitter Yofalikira
1. Makhalidwe Apakatikati
The mankhwala ndi thupi chikhalidwe cha ndondomeko madzimadzi mwachindunji zimakhudza ngakhale sensa.
Zoyenera:Magesi, mafuta, zakumwa zoyera - zomwe zimagwiritsidwa ntchito ndi masensa osapanga dzimbiri a 316L.
Zosayenera:Zinthu zowononga kwambiri, zowoneka bwino, kapena zowoneka bwino - izi zitha kutseka kapena kuwononga sensa.
Malangizo:
- Zamadzimadzi zowoneka bwino (monga slurries, syrups): Gwiritsani ntchito ma transmitters a diaphragm kuti musatseke.
- Ntchito zaukhondo (mwachitsanzo, chakudya, mankhwala): Sankhani ma tri-clamp flush diaphragm (≤4 MPa kuti muyike bwino).
- Makanema olemetsa (monga matope, phula): Gwiritsani ntchito ma diaphragm opanda zibowo, osagwira ntchito pang'ono ~ 2 MPa.
⚠️ Chenjezo: Osakhudza kapena kukanda diaphragm ya sensor - ndiyofewa kwambiri.
2. Pressure Range
Muyezo woyezera: -0.1 MPa mpaka 60 MPa.
Nthawi zonse sankhani cholumikizira chovotera pang'ono kuposa kukakamiza kwanu kokwanira kuti mutetezeke komanso kulondola.
Pressure unit reference:
1 MPa = 10 bar = 1000 kPa = 145 psi = 760 mmHg ≈ mita 100 mzere wamadzi
Gauge vs. Absolute Pressure:
- Kuthamanga kwa gauge: kumatanthawuza kupsinjika kwamlengalenga.
- Kupanikizika kotheratu: kumatanthawuza ku vacuum yabwino.
Zindikirani: M'madera okwera, gwiritsani ntchito ma transmitters olowera mpweya (okhala ndi machubu olowera) kuti mubwezere kuthamanga kwamlengalenga pakafunika kulondola (
3. Kutentha Kugwirizana
Nthawi yogwira ntchito: -20°C mpaka +80°C.
Pazotengera kutentha kwambiri (mpaka 300 ° C), ganizirani:
- Zipsepse zoziziritsa kuzizira kapena zomangira kutentha
- Ma diaphragm akutali amasindikizidwa ndi ma capillaries
- Limbikitsani machubu kuti mulekanitse sensa ku kutentha kwachindunji
4. Kupereka Mphamvu
Kupereka kwanthawi zonse: DC 24V.
Mitundu yambiri imavomereza 5–30V DC, koma pewani zolowetsa pansi pa 5V kuti mupewe kusakhazikika kwa ma sign.
5. Mitundu ya Zizindikiro Zotulutsa
- 4–20 mA (2-waya): Muyezo wamakampani pamayendedwe atalitali komanso osasokoneza
- 0–5V, 1–5V, 0–10V (3-waya): Yabwino pama pulogalamu aafupi
- RS485 (digito): Kwa serial communication and networked systems
6. Njira Connection Threads
Mitundu ya ulusi wamba:
- M20×1.5 (metric)
- G1/2, G1/4 (BSP)
- M14 × 1.5
Fananizani mtundu wa ulusi ndi chizolowezi chamakampani komanso zomwe zimafunikira pamakina anu.
7. Kalasi Yolondola
Miyezo yolondola yeniyeni:
- ± 0.5% FS - muyezo
- ± 0.3% FS - mwatsatanetsatane kwambiri
⚠️ Pewani kufotokoza kulondola kwa ± 0.1% FS kwa ma transmitters ophatikizika a silicon. Sanakonzedwe kuti agwire ntchito yolondola kwambiri pamlingo uwu. M'malo mwake, gwiritsani ntchito zitsanzo za silicon za monocrystalline pazochita zoterezi.
8. Malumikizidwe a Magetsi
Sankhani malinga ndi zomwe mukufuna kukhazikitsa:
- DIN43650 (Hirschmann): Kusindikiza kwabwino, komwe kumagwiritsidwa ntchito kwambiri
- Pulagi ya Aviation: Kuyika kosavuta ndikusintha
- Chingwe cholunjika: Cholimba komanso chosamva chinyezi
Kuti mugwiritse ntchito panja, sankhani nyumba zamtundu wa 2088 kuti muzitha kuteteza nyengo.
Mfundo Zapadera za Nkhani
Q1: Kodi ndingayeze mpweya wa ammonia?
Inde, koma ndi zipangizo zoyenera (mwachitsanzo, Hastelloy diaphragm, PTFE seals). Komanso, ammonia imakhudzidwa ndi mafuta a silicone - gwiritsani ntchito mafuta a fluorinated ngati madzi odzaza.
Q2: Nanga bwanji zoyaka kapena zophulika?
Pewani mafuta a silicone okhazikika. Gwiritsani ntchito mafuta a fluorinated (mwachitsanzo, FC-70), omwe amapereka kukhazikika kwa mankhwala komanso kukana kuphulika.
Mapeto
Chifukwa cha kudalirika kwawo, kusinthika, komanso kukwera mtengo, ma transmitters ophatikizika a silicon amakhalabe njira yothetsera mafakitale osiyanasiyana.
Kusankhidwa mosamala kutengera sing'anga, kupanikizika, kutentha, mtundu wolumikizira, ndi kulondola kumatsimikizira kugwira ntchito bwino komanso kukhazikika kwanthawi yayitali.
Mukufuna thandizo posankha chitsanzo choyenera?
Tiuzeni pulogalamu yanu—tikuthandizani kupeza yoyenera.
