ʻO ke alakaʻi hope loa i ke koho ʻana i kahi mea hoʻouna kaomi silikoni hoʻoheheʻe
Ma waena o nā ʻano o nā mea hoʻoili puʻupuʻu - me ka ceramic, capacitive, a me ka monocrystalline silicon variants-diffused silicon pressure transmitters ua lilo i mea hoʻonā nui loa no nā noi ana ʻoihana.
Mai ka aila a me ke kinoea a hiki i ka hana kemika, ka hana kila, ka hana mana, a me ka ʻenekinia kaiapuni, hāʻawi kēia mau transmitters i ka nānā pono a me ka pololei o ka kaomi ma waena o ke kaomi ana, ke kaomi piha, a me nā noi vacuum.
He aha ke ʻano o ka mea hoʻouna ʻo Silicon Pressure Transmitter?
Ua hoʻokumu ʻia ka ʻenehana i ka waena o 1990s i ka wā i hoʻokumu ai ʻo NovaSensor (USA) i nā diaphragms silicon micro-machined i hoʻopaʻa ʻia me ke aniani. Ua hoʻokumu kēia holomua i nā mea ʻike paʻa kiʻekiʻe me ka hoʻihoʻi hou ʻana a me ka pale ʻana i ka corrosion.
Kuʻuna Hana
- Hoʻouna ke kaomi kaʻina hana ma o kahi diaphragm kaʻawale a me ka ʻaila silicone i kahi diaphragm silicon
- Pili ke kaomi kuhikuhi (ambient a i ʻole vacuum) i ka ʻaoʻao ʻē aʻe
- ʻIke ʻia ka hopena deflection e kahi alahaka Wheatstone o nā ana kānana, e hoʻohuli ana i ke kaomi i hōʻailona uila.
8 Koho Koho Pono
1. Ana ʻia ʻo Medium Compatibility
Pono ka mea ʻike i nā mea kemika a me nā waiwai kino o kāu wai kaʻina hana:
- Hoʻohana nā hoʻolālā maʻamau i nā diaphragms stainless steel 316L no ka nui o nā noi
- No nā wai ʻino a i ʻole ka kristal, e kuhikuhi i nā mea hoʻolele diaphragm flush
- Loaʻa nā koho meaʻai no nā lāʻau lapaʻau a me nā mea inu
- Pono nā pāpaho kiʻekiʻe (slurry, mud, asphalt) i nā hoʻolālā diaphragm flush-free cavity.
2. Koho Pumi
Loaʻa nā pae mai -0.1 MPa a hiki i 60 MPa. E koho mau i kahi ākea 20-30% kiʻekiʻe ma mua o kāu kaomi hana kiʻekiʻe e pale ai i ka hoʻouka ʻana.
Ke alakaʻi hoʻololi ʻana i ka Unit Pressure
| Unite | Waiwai Kaulike |
|---|---|
| 1 MPa | 10 bar / 1000 kPa / 145 psi |
| 1 pahu | 14.5 psi / 100 kPa / 750 mmHg |
ʻO ke ana kūʻē.ʻO ke kaomi ana e kuhikuhi ana i ke kaomi ambient (zero e like me ka lewa), aʻo ke kaomi paʻa e kuhikuhi ana i ka hakahaka. No nā noi kiʻekiʻe, e hoʻohana i nā mea ʻike kiʻekiʻe e hoʻopaʻi i nā ʻano like ʻole o ka lewa kūloko.
Noonoo Noi
Ana kinoea Ammonia
E wehewehe i nā diaphragms i hoʻopaʻa ʻia i ke gula a i ʻole nā pale anti-corrosive kūikawā e pale ai i ka hōʻino ʻana o ka sensor ma ka lawelawe amonia. E hōʻoia i ka hui ʻana o ka hale transmitter i nā helu NEMA 4X a i ʻole IP66 no nā hoʻonohonoho waho.
Hoʻokomo ʻia nā wahi pōʻino
No nā wahi ʻā a pahū paha:
- Noi i ka aila fluorinated (FC-40) ma kahi o ka aila silicone maʻamau
- E hōʻoia i nā palapala hōʻoia no nā noi palekana (Ex ia) a i ʻole flameproof (Ex d).
- E hōʻoia i ka hoʻokumu ʻana i ke kahua kūpono a me ka hoʻonohonoho ʻana i nā pale ma nā kūlana IEC 60079
Ka hopena
Hāʻawi nā mea hoʻolele kaomi silicon diffused i kahi kaulike kūpono o ka pololei, ka lōʻihi, a me ka versatility ma waena o nā kaʻina hana. ʻO ke koho kūpono—mai ka loiloi like ʻana o ka media a hiki i ka kikoʻī hōʻailona hoʻopuka—e hōʻoia i ka pololei o ke ana a me ka hilinaʻi lōʻihi.
ʻO ka nānā ʻana i nā laina mokumahu puʻu kiʻekiʻe, kaohi ʻana i nā hopena kemika, a i ʻole ka hōʻoia ʻana i ka mālama ʻana i ka ammonia palekana, hoʻonui ka hoʻonohonoho transmitter kūpono i ka pono o ke kaʻina hana a me ka palekana hana.
