ʻano hoʻohui sensor

ʻO ka uwila o nā mea ʻike ʻo ia kekahi o nā nīnau i nīnau pinepine ʻia i ke kaʻina kūʻai o nā mea kūʻai. ʻAʻole ʻike ka nui o nā mea kūʻai aku i ka hoʻopaʻa ʻana i nā mea ʻike. ʻO ka ʻoiaʻiʻo, ʻo nā ala wili o nā ʻano sensor like ʻole. Loaʻa i nā ʻenekia kaomi ʻelua uea, ʻekolu uea, ʻehā uea a me kekahi mau ʻōnaehana ʻelima.

He mea maʻalahi ka ʻōnaehana ʻelua uea o ka sensor kaomi, a ʻike ka hapa nui o nā mea kūʻai aku pehea e hoʻopili ai i nā uea. Hoʻohui ʻia kekahi uea i ka pou maikaʻi o ka mana lako, a ʻo ka uea ʻē aʻe, ʻo ia hoʻi, ka uea hōʻailona, ​​ua hoʻopili ʻia i ka pou maikaʻi ʻole o ka lako mana ma o nā mea kani, ʻo ia ka mea maʻalahi. Hoʻokumu ʻia ka ʻōnaehana ʻekolu uea o ka mīkini paʻi ma luna o ka ʻōnaehana ʻelua-uea, a ua pili pono kēia uea i ka pole maikaʻi ʻole o ka lako mana, ʻoi aku ka pilikia ma mua o ka ʻōnaehana ʻelua. Pono ʻelua mau mana hoʻokomo ʻana i ka ʻenekona ʻehā uea, a ʻo nā mea ʻelua ʻelua he mau hōʻailona hōʻailona. ʻO ka hapa nui o nā ʻōnaehana uila ʻehā he puka uila ma kahi o 4 ~ 20mA puka, a ʻo 4 ~ 20mA ka mea i kapa ʻia ʻo pressure transmitter, a ʻo ka hapa nui o lākou i hana ʻia i ʻelua ʻōnaehana uea. ʻAʻole i hoʻonui ʻia kekahi o nā hoʻopuka hōʻailona o nā mea ʻike puʻupuʻu, a ʻo ka puka piha piha he ʻumi wale nō o millivolts, ʻoiai ʻo kekahi mau mea ʻike puʻupuʻu he amplification circuits i loko, a ʻo ka hoʻopuka piha ʻana he 0 ~ 2V. No ke ʻano o ka hoʻopili ʻana i ka mea hana hōʻike, pili ia i ke ana ʻana o ka mea kani. Inā loaʻa kahi hāmeʻa kūpono no ka hōʻailona hoʻopuka, hiki ke ana pololei ʻia, inā ʻaʻole, pono e hoʻohui ʻia kahi kaapuni hoʻoponopono hōʻailona. ʻAʻole liʻiliʻi ka ʻokoʻa ma waena o ka ʻenekona ʻelima uea a me ka ʻenekona kaomi ʻehā, a ʻoi aku ka liʻiliʻi o nā ʻenekini ʻelima uea ma ka mākeke.

ʻO ka sensor kaomi kekahi o nā mea i hoʻohana nui ʻia. ʻO nā ʻenekini puʻe kuʻuna maʻamau ka mea maʻamau, e hōʻike ana i ke kaomi e ka deformation o nā mea elastic, akā nui kēia ʻano i ka nui a kaumaha i ke kaumaha, ʻaʻole hiki ke hāʻawi i ka hoʻopuka uila. Me ka hoʻomohala ʻana o ka ʻenehana semiconductor, ua hoʻokumu ʻia nā mea ʻike kaomi semiconductor. Hōʻikeʻia ia e ka leo liʻiliʻi, ke kaumaha māmā, ka pololei kiʻekiʻe a me nāʻano wela maikaʻi. ʻOi aku me ka hoʻomohala ʻana o ka ʻenehana MEMS, ke hoʻomohala nei nā mea ʻike semiconductor i ka miniaturization me ka hoʻohana haʻahaʻa haʻahaʻa a me ka hilinaʻi kiʻekiʻe.
