Phau Ntawv Qhia Qhov Kawg rau Kev Xaiv Ib Lub Diffused Silicon Pressure Transmitter
Ntawm ntau hom kev hloov pauv siab-xws li ceramic, capacitive, thiab monocrystalline silicon variants-diffused silicon siab transmitters tau dhau los ua cov kev siv dav tshaj plaws rau kev ntsuas kev lag luam.
Los ntawm cov roj & roj mus rau kev ua tshuaj lom neeg, kev tsim steel, tsim hluav taws xob, thiab ib puag ncig engineering, cov khoom xa tawm no xa cov kev ntsuas siab thiab raug saib xyuas thoob plaws qhov ntsuas siab, siab siab, thiab kev siv lub tshuab nqus tsev.
Dab tsi yog Diffused Silicon Pressure Transmitter?
Cov thev naus laus zis tau tshwm sim nyob rau nruab nrab-1990s thaum NovaSensor (USA) pioneered micro-machined silicon diaphragms bonded nrog iav. Qhov kev ua txhaum no tau tsim compact, high-precision sensors nrog tshwj xeeb repeatability thiab corrosion kuj.
Txoj Cai Kev Ua Haujlwm
- Cov txheej txheem siab kis tau los ntawm kev sib cais diaphragm thiab silicone roj mus rau silicon diaphragm
- Kev siv siab (ambient lossis nqus tsev) siv rau sab nraud
- Qhov tshwm sim deflection yog kuaj pom los ntawm tus choj Wheatstone ntawm cov ntsuas ntsuas, hloov siab rau hauv lub teeb liab hluav taws xob
8 Yam Kev Xaiv Qhov Tseem Ceeb
1. Ntsuas nruab nrab Compatibility
Cov khoom siv sensor yuav tsum phim cov tshuaj thiab lub cev ntawm koj cov txheej txheem dej:
- Cov qauv tsim siv 316L stainless hlau diaphragms rau feem ntau daim ntawv thov
- Rau cov kua dej corrosive los yog crystallizing, qhia meej diaphragm transmitters
- Cov kev xaiv zaub mov qib muaj rau kev siv tshuaj thiab dej haus
- High-viscosity media (slurry, av nkos, asphalt) yuav tsum muaj kab noj hniav tsis muaj dej yaug diaphragm tsim
2. Kev xaiv qhov siab
Muaj qhov sib txawv ntawm -0.1 MPa rau 60 MPa. Ib txwm xaiv qhov ntau ntawm 20-30% siab dua koj qhov siab tshaj plaws kev khiav hauj lwm los tiv thaiv overloading.
Pressure Unit Conversion Guide
| Chav tsev | Tus nqi sib npaug |
|---|---|
| 1 MPa | 10 bar / 1000 kPa / 145 psi |
| 1 bar | 14.5 psi / 100 kPa / 750 mmHg |
Gauge vs. Absolute Pressure:Kev ntsuas siab hais txog ambient siab (zero sib npaug ntawm huab cua), thaum lub siab tsis txaus ntseeg lub tshuab nqus tsev. Rau kev siv high-altitude, siv vented gauge sensors los them rau cov kev hloov hauv cheeb tsam atmospheric.
Kev txiav txim siab tshwj xeeb ntawm daim ntawv thov
Kev ntsuas roj ammonia
Qhia meej kub-plated diaphragms los yog tshwj xeeb los tiv thaiv corrosive txheej los tiv thaiv sensor degradation nyob rau hauv ammonia kev pab cuam. Xyuas kom lub transmitter vaj tse raws li NEMA 4X los yog IP66 kev ntsuam xyuas rau kev teeb tsa sab nraum zoov.
Kev Teeb Meem Hauv Cheeb Tsam
Rau ib puag ncig flammable los yog tawg:
- Thov cov roj fluorinated (FC-40) es tsis txhob siv cov roj silicone roj sau
- Txheeb xyuas cov ntawv pov thawj rau kev nyab xeeb (Ex ia) lossis cov ntawv thov flameproof (Ex d)
- Xyuas kom muaj av thiab thaiv kev teeb tsa raws li IEC 60079 tus qauv

Diffused silicon siab transmitters muab qhov zoo sib npaug ntawm precision, durability, thiab versatility nyob rau hauv cov txheej txheem kev lag luam. Kev xaiv kom raug - los ntawm kev ntsuas kev sib raug zoo hauv xov xwm mus rau cov teeb liab qhia tshwj xeeb - ua kom muaj kev ntsuas qhov tseeb thiab kev ntseeg tau ntev.
Txawm hais tias saib xyuas cov kab hluav taws xob siab, tswj cov tshuaj lom neeg, lossis ua kom muaj kev nyab xeeb ntawm ammonia, kev teeb tsa txoj cai transmitter txhim kho cov txheej txheem kev ua haujlwm thiab kev nyab xeeb ntawm kev ua haujlwm.
