He kūpono no ka excavator oil pressure pressure sensor 161-1704

Pūnaehana loaʻa wela BMS a me ke ʻano ana e pili ana i ka sensor wela NTC

ʻO ka ʻenehana patent e pili ana i ke kahua o ka loaʻa ʻana o ka mahana pākaukau o nā kaʻa uila, ʻoiai me kahi ʻōnaehana loaʻa wela BMS e pili ana i ka sensor wela NTC a me kahi ʻano ana.

I kēia manawa, hoʻohana nui ʻia nā mea ʻike wela i ke kahua o ka ikehu hou, ʻoi loa ka ʻōnaehana hoʻokele pākaukau o nā kaʻa ikehu hou, ʻo ia hoʻi ʻo BMS. I kēia manawa, hoʻohana pinepine ʻia ka mea ʻike wela kūpaʻa (RTD) a me ka thermocouple i hui pū ʻia me nā kaapuni ana like e hōʻiliʻili i ka mahana. Hoʻokomo ʻia nā kaʻapuni laʻana wela i ke ʻano o ka hoʻokaʻawale ʻana i ka volta kūʻē a me ke ʻano o ka hoʻoulu ʻana i ke kumu o kēia manawa. Eia nō naʻe, ʻo nā ʻano hana i luna aʻe nei nā hemahema: 1. He paʻakikī ka loaʻa ʻana o ka hōʻailona analog RTD a me ka hana kaʻapuni a he kiʻekiʻe ke kumukūʻai. ʻO ka mana i koi ʻia no ka ʻike e hoʻoikaika ʻia e lawe mai i ka piʻi ʻana o ka wela o loko a hoʻonui i ka hewa ana ʻana. I ka manawa like, he kiʻekiʻe ke kumukūʻai o kēia hoʻolālā, a he nui ka leo kaapuni o ka ʻāpana kūʻai, ʻaʻole kūpono i ka miniaturization. 2. Ma muli o ka haʻahaʻa haʻahaʻa o ka thermocouple, pono e hoʻonui i ka hōʻailona i hōʻiliʻili ʻia me kahi mea hoʻonui haʻahaʻa offset. Eia kekahi, ʻilihune ka linearity wela o ka thermocouple, no laila pono e uku i ke kaapuni, kahi e hoʻonui ai i ka hewa sampling a hoʻemi i ka pololei sampling. 3. I kēia manawa, ʻoi aku ka maʻamau o ke ʻano o ka thermistor i hui pū ʻia me ka puʻuwai puʻupuʻu. ʻO ke kumu nui o ka hoʻokomo ʻana i kēia hoʻolālā he ʻokoʻa nā ʻano thermistor a haʻahaʻa ke kumukūʻai. Eia naʻe, haʻahaʻa ka pololei o ka loaʻa ʻana o ka thermistor; No ka hōʻuluʻuluʻana, he paʻakikī ka pono o ka loaʻaʻana o ka mahana wela. ʻO ka manaʻo i nā hemahema o ka papahana loaʻa wela e kū nei, ke waiho nei kēia pepa i kahi ala kiʻekiʻe a me ke kumu kūʻai haʻahaʻa e loaʻa ai ka wela, i kūpono no nā ʻōnaehana hoʻokele pākaukau ikehu hou a me nā kula ʻē aʻe.
