Reed Sensors vs. Hall Effect Sensors

Reed Sensors vs. Hall Effect Sensors

Hoʻohana pū nā mea ʻike Hall Effect i ka hiki ʻana o ka mana magnetic e mana i ka wehe ʻana a me ka pani ʻana o kahi hoʻololi, akā ʻo ia kahi i pau ai ko lākou like. ʻO kēia mau mea ʻike he semiconductor transducers e hoʻopuka ana i ka volta e hoʻāla i nā hoʻololi paʻa-mokuʻāina ma mua o nā hoʻololi me nā ʻāpana neʻe. ʻO kekahi mau ʻokoʻa koʻikoʻi ma waena o nā ʻano hoʻololi ʻelua:

Ka lōʻihi. Pono paha nā mea ʻike ʻo Hall Effect i ka ʻeke hou e pale aku iā lākou mai ke kaiapuni, akā mālama ʻia nā mea ʻike ʻohe i loko o nā pahu hermetically sila. Eia naʻe, no ka hoʻohana ʻana o nā mea ʻike ʻohe i ka neʻe mechanical, ʻoi aku ka maʻalahi o ka lole a me ka waimaka.
Koi uila. Pono nā hoʻololi o Hall Effect i ke kahe mau o kēia manawa. ʻO nā mea ʻike ʻo Reed, ma ka ʻaoʻao ʻē aʻe, koi wale i ka mana e hoʻohua i kahi māla magnetic i waena.
Pilikia i ke keakea. Hiki ke hoʻololi i nā hoʻololi Reed i ka haʻalulu mechanical i kekahi mau kaiapuni, ʻoiai ʻaʻole nā ​​hoʻololi Hall Effect. ʻO nā hoʻololi o Hall Effect, ma kekahi ʻaoʻao, ʻoi aku ka maʻalahi o ka hoʻopili electromagnetic (EMI).
Laulā pinepine. Hiki ke hoʻohana ʻia nā mea ʻike hopena Hall ma kahi ākea ākea, aʻo nā mea ʻike ʻohe i kaupalena ʻia i nā noi me nā alapine ma lalo o 10 kHz.
Koina. ʻOi aku ka maikaʻi o nā ʻano sensor ʻelua, akā ʻoi aku ka liʻiliʻi o nā sensor reed holoʻokoʻa e hana ai, ʻoi aku ka maikaʻi o nā mea ʻike Hall Effect.
Kūlana wela. ʻOi aku ka maikaʻi o nā mea ʻike ʻo Reed i nā wela wela a i ʻole ke anuanu, ʻoiai nā mea ʻike Hall Effect e ʻike i nā pilikia hana i ka wela wela.
