ʻO ka wehewehe pōkole:
Ke hoʻohana nei i ke kumu o ke ana wela o ka nalu acoustic surface, ka ʻike wela i loko o nā ʻāpana hōʻailona alapine electromagnetic. Hoʻokomo pololei ʻia ka ʻike wela ma luna o ka ʻili o nā ʻāpana wela o ka mea i ana ʻia, nona ke kuleana no ka loaʻa ʻana o ka hōʻailona lekiō, a hoʻihoʻi i ka lekiō me ka ʻike wela i ka ʻohi, ke hana maʻamau ka ʻike wela, ʻaʻole pono ia i ka mana o waho. lako e like me ka pākaukau, CT loop power supply. Hoʻomaopopo ʻia ka hoʻoili ʻana o ke kahua hōʻailona ma waena o ka sensor wela a me ka ʻohi wela e nā hawewe electromagnetic uila.
