Pili i nā ʻāpana CAT excavator E330C Oil Pressure Sensor 161-1703

ʻO ke kumu kumu o ka ʻenehana hoʻohuihui ʻikepili lehulehu e like me ke kaʻina hana o ka lolo o ke kanaka ka hoʻoili ʻana i ka ʻike, ka mea e hoʻokō a hoʻomaikaʻi i ka ʻike o nā ʻike like ʻole i nā pae he nui a me ka nui-space, a ma hope e hoʻopuka i kahi wehewehe kūlike o ka nānā. kaiapuni. Ma kēia kaʻina hana, pono mākou e hoʻohana piha i ka ʻikepili kumu nui no ka mana kūpono a me ka hoʻohana ʻana, a ʻo ka pahuhopu hope loa o ka hui ʻana o ka ʻike e loaʻa i ka ʻike ʻoi aku ka maikaʻi ma o ka hui pū ʻana o nā ʻike he nui a me nā ʻano like ʻole e pili ana i ka ʻike ʻike i hoʻokaʻawale ʻia. loaʻa i kēlā me kēia mea ʻike. ʻAʻole wale kēia e hoʻohana pono i ka hana like ʻana o nā mea naʻau he nui, akā e hoʻopololei pū i ka ʻikepili mai nā kumu ʻike ʻē aʻe e hoʻomaikaʻi i ka naʻauao o ka ʻōnaehana sensor holoʻokoʻa.

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.

Mea hoʻolele puʻupuʻu silika diffusion

Hana ʻia ka mea hoʻoheheʻe kilika kilika ma ka encapsulating silicon piezoresistive pressure sensor me kahi kaʻawale i loko o ka pūpū kila. Hiki iā ia ke hoʻololi i ka wai i ʻike ʻia a i ʻole ke kaomi kinoea i kahi hōʻailona uila maʻamau no ka puka waho. Hoʻohana nui ʻia ka DATA-52 series diffused silicon pressure transmitter no ke ana ʻana a me ka mālama ʻana i nā kaʻina hana ʻoihana e like me ka lako wai/drainage, wela, ʻaila, ʻoihana kemika a me ka metallurgy.
