ʻO nā pono nui o E + H pressure transmitter:
1. Loaʻa i ka mea hoʻouna kaomi ka hana hilinaʻi a me ka hana paʻa.
2. Kūikawā V / I integrated circuit, liʻiliʻi liʻiliʻi nā mea pili, hilinaʻi kiʻekiʻe, maʻalahi a maʻalahi ka mālama ʻana, liʻiliʻi liʻiliʻi, ke kaumaha māmā, kūpono loa ka hoʻonohonoho ʻana a me ka debugging.
3. Aluminum alloy make-casting shell, ʻekolu hopena kaʻawale, electrostatic spray protection layer, ikaika a paʻa.
4. 4-20mA DC ʻelua-wire hōʻailona hoʻoili, ikaika anti-interference hiki a me ka lōʻihi mamao mamao.
5. ʻO LED, LCD, kuhikuhi ʻekolu ʻano hōʻailona, ʻoi aku ka maʻalahi o ka heluhelu kula.Hiki ke hoʻohana ʻia no ke ana ʻana i ka media viscous, crystalline a corrosive.
6. Kiʻekiʻe pololei a me ka paʻa.Ma waho aʻe o nā mea ʻike mua i lawe ʻia mai i hoʻoponopono ʻia e ka laser, ua uku maikaʻi ʻia ka holo ʻana o ka wela piha a me ka nonlinearity o ka mīkini holoʻokoʻa i loko o ka pae wela o ka hana.
Hana: hoʻouna ka E + H pressure transmitter i ka hōʻailona kaomi i nā mea uila, a laila hōʻike i ke kaomi ma ke kamepiula.ʻO ke kumumanaʻo e like me kēia: ua hoʻololi ʻia ka hōʻailona mechanical o ke kaomi wai i kēia manawa (4-20mA).ʻO ke kaomi o ia hōʻailona uila ma ka pilina laina me ka volta a i ʻole ke au, ʻo ia ka mea maʻamau.No laila, hoʻonui ka volta a i ʻole ka puka o kēia manawa e ka transmitter me ka piʻi ʻana o ke kaomi, a loaʻa kahi pilina ma waena o ke kaomi a me ka uila a i ʻole ka manawa.
Hoʻokomo ʻia nā paʻi ʻelua o ka mea i ana ʻia o ka mea hoʻouna kaomi E + H i loko o nā keʻena kiʻekiʻe a haʻahaʻa.ʻO ke kaomi o ke keʻena haʻahaʻa haʻahaʻa he kaomi lewa a i ʻole ka vacuum, e hana ana i nā diaphragms kaʻawale ma nā ʻaoʻao ʻelua o ka mea koʻikoʻi a hoʻouna ʻia i nā ʻaoʻao ʻelua o ka diaphragm ana ma o ka figueris isolation diaphragm a me ka wai hoʻopiha i ka mea.ʻO ka mea hoʻoili kaomi he capacitor i hoʻokumu ʻia i ka diaphragm ana a me nā electrodes ma nā ʻaoʻao insulating ma nā ʻaoʻao ʻelua.Ke kulike ole na kaomi ana ma na aoao elua, ua like ka nee ana o ka diaphragm ana i ka okoa pumi, no laila, ua like ole na capacitances ma na aoao elua, a ua hoololiia i mau hoailona e like me ke kaomi ma o ka oscillation a me ka demodulation.Hiki i ka E + H pressure transmitter ke ʻike i ke kaomi o nā mea like ʻole, inā he paʻa, wai a i ʻole ke kinoea, no laila ua hoʻohana ʻia i nā kula he nui.
