I ka ʻoihana ʻoihana, hoʻohana nui ʻia nā sensor kaomi i nā lako like ʻole a me nā ʻōnaehana. No ka laʻana, i nā ʻōnaehana hydraulic, nā ʻōnaehana kaomi ea, nā ʻōnaehana refrigeration, a me nā mea ʻē aʻe, hiki i nā mea ʻike kaomi ke nānā i nā loli kaomi i ka manawa maoli e hōʻoia i ka hana maʻamau o ka ʻōnaehana. Ma ke kahua kaʻa kaʻa, hoʻohana pū ʻia nā mea ʻike kaomi i nā mīkini, nā ʻōnaehana brake, nā kaila a me nā mea ʻē aʻe e hōʻoia i ka palekana a me ka hana o ke kaʻa. Eia kekahi, ma ke kahua aerospace, he mea koʻikoʻi hoʻi nā mea ʻike kaomi i ka nānā ʻana i ke ea a me nā loli kiʻekiʻe o nā mokulele, rockets a me nā mokulele ʻē aʻe.
