Iyo Yekupedzisira Nhungamiro Yekusarudza Yakapararira Silicon Pressure Transmitter
Pakati pemhando dzakawanda dzekudzvanya-kusanganisira ceramic, capacitive, uye monocrystalline silicon variants-yakapararira silicon pressure transmitters yave iyo yakanyanya kugamuchirwa mhinduro yekuyera maindasitiri.
Kubva kuoiri & gasi kuenda kukugadzira makemikari, kugadzirwa kwesimbi, kugadzirwa kwemagetsi, uye engineering yezvakatipoteredza, aya ma transmitters anounza akavimbika uye akanyatso kudzvanya kutarisisa pane gauge pressure, absolute pressure, uye vacuum application.
Chii chinonzi Diffused Silicon Pressure Transmitter?
Iyo tekinoroji yakatanga pakati pe-1990s apo NovaSensor (USA) yakapayona micro-machine silicon diaphragms yakasungwa negirazi. Kubudirira uku kwakagadzira compact, yakakwirira-chaiyo sensors ine yakasarudzika inodzokororwa uye corrosion kuramba.
Operating Principle
- Kudzvanywa kwemaitiro kunofambisa kuburikidza nediaphragm yekuzviparadzanisa nevamwe uye silicone mafuta kune silicon diaphragm
- Reference pressure (ambient or vacuum) inoshanda kune rimwe divi
- Mhedzisiro inokonzeresa inowonekwa ne Wheatstone bhiriji remajeji ekusekana, kushandura kudzvanywa kuita chiratidzo chemagetsi.
8 Yakakosha Sarudzo Maitirwo
1. Measured Medium Compatibility
Iyo sensor material inofanirwa kuenderana nemakemikari uye emuviri zvimiro zve process fluid yako:
- Magadzirirwo akajairwa anoshandisa 316L Stainless simbi diaphragms kune akawanda maapplication
- Pazvinwiwa zvinoparadza kana kupenya, tsanangura zvinotamisa diaphragm
- Chikafu-giredhi sarudzo dziripo dzemishonga uye zvinwiwa application
- High-viscosity media (slurry, dope, asphalt) inoda dhizaini-isina dhizaini diaphragm dhizaini.
2. Pressure Range Selection
Inowanikwa nhanho kubva -0.1 MPa kusvika 60 MPa. Gara uchisarudza huwandu 20-30% yakakwirira kupfuura yako yakanyanya kushanda kumanikidza kudzivirira kuwandisa.
Pressure Unit Conversion Guide
| Unit | Kuenzana Kukosha |
|---|---|
| 1 MPa | 10 bar / 1000 kPa / 145 psi |
| 1 bar | 14.5 psi / 100 kPa / 750 mmHg |
Gauge vs. Absolute Pressure:Gauge pressure reference ambient pressure (zero yakaenzana nemhepo), ukuwo absolute pressure references vacuum. Pamaapplications epamusoro-soro, shandisa mavented gauge sensors kutsiva kusiyana kwemuchadenga.
Mafungiro Anokosha Ekushandisa
Ammonia Gasi Kuyera
Rondedzera madiaphragm ane goridhe-akapfatwa kana akakwenenzverwa anti-corrosive coatings kudzivirira kushatisa sensor musevhisi yeammonia. Ita shuwa kuti transmitter imba inosangana neNEMA 4X kana IP66 ratings yekumisikidzwa kwekunze.
Nengozi Nzvimbo Installations
Kunzvimbo dzinopisa kana kuputika:
- Kumbira oiri yefluorinated (FC-40) pachinzvimbo cheyakajairwa silicone oiri zadza
- Simbisa zvitupa zvemukati zvakachengeteka (Ex ia) kana zvisingabatike moto (Ex d) maapplication.
- Ita shuwa yekudzika kwakaringana uye yekuvharira kuisirwa paIEC 60079 zviyero
Mhedziso
Diffused silicon pressure transmitters inopa yakaringana chiyero chechokwadi, kusimba, uye kuita kwakasiyana-siyana mumaindasitiri maitiro. Sarudzo yakakodzera-kubva pakuongorora kuenderana nevezvenhau kusvika kune inobuda chiratidzo-inovimbisa zvese kuyerwa kurongeka uye kuvimbika kwenguva refu.
Ingave yekutarisa yakakwira-kudzvanywa mitsara yemhepo, kudzora maitiro emakemikari, kana kuona yakachengeteka kubata ammonia, iyo chaiyo transmitter kumisikidzwa inosimudzira zvese kushanda zvakanaka uye kuchengetedzwa kwekushanda.
