Hoʻohana ʻia nā thermistors wela wela (NTC) e like me nā ʻāpana sensor wela kiʻekiʻe i nā ʻano like ʻole o ka automotive, ʻoihana, mea hana hale a me nā noi olakino.No ka loaʻa ʻana o ka nui o nā thermistors NTC - hana ʻia me nā hoʻolālā like ʻole a hana ʻia mai nā ʻano mea like ʻole - koho i ka maikaʻi loa.Nā mea wela NTCno ka mea hiki ke paʻakikī kekahi noi.
No ke aha maikohoNTC?
ʻEkolu mau ʻenehana ʻike wela nui, ʻo kēlā me kēia me kona mau hiʻohiʻona: nā mea ʻike wela kū'ē (RTD) a me nā ʻano ʻelua o nā thermistors, nā thermistors coefficient mahana maikaʻi a maikaʻi ʻole.Hoʻohana mua ʻia nā mea ʻike RTD e ana i kahi ākea o nā wela, a no ka hoʻohana ʻana i ka metala maʻemaʻe, ʻoi aku ka nui o ke kumukūʻai ma mua o nā thermistors.
No laila, no ke ana ʻana o nā thermistors i ka mahana me ka pololei a ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi ma mua o RTDS.E like me ka manaʻo o ka inoa, piʻi ke kū'ē o ka thermistor wela maikaʻi (PTC) me ka mahana.Hoʻohana maʻamau ʻia lākou e like me nā mea ʻike palena wela ma nā kaʻa kaʻa a i ʻole ka palekana no ka piʻi ʻana o ke kūpaʻa i ka wā e hiki ai ka mahana hoʻololi.Ma ka ʻaoʻao ʻē aʻe, i ka piʻi ʻana o ka mahana, e emi ana ke kūpaʻa o ka thermistor kino ʻole (NTC).ʻO ke kū'ē i ka pilina o ka wela (RT) he pihi palahalaha, no laila pololei loa a paʻa no nā ana wela.
Nā pae koho koʻikoʻi
ʻO nā thermistors NTC ka mea maʻalahi a hiki ke ana i ka mahana me ka pololei kiʻekiʻe (± 0.1 ° C), e hoʻolilo iā lākou i mea kūpono no kahi ākea o nā noi.Eia nō naʻe, ʻo ke koho ʻana i ke ʻano o ke ʻano e hōʻike ʻia e pili ana i ka nui o nā pae hoʻohālikelike - ka pae wela, ka laulā kūʻē, ka pololei o ke ana ʻana, ke kaiapuni, ka manawa pane, a me nā koi nui.
ʻOi aku ka ikaika o nā mea NTC i uhi ʻia i ka epoxy a e ana maʻamau i nā mahana ma waena o -55°C a me + 155°C, aʻo nā mea NTC i hoʻopaʻa ʻia i ke aniani ke ana a hiki i + 300°C.No nā noi e koi ana i nā manawa pane wikiwiki loa, ʻoi aku ka kūpono o nā mea i hoʻopaʻa ʻia i ke aniani.ʻOi aku ka liʻiliʻi o lākou, me nā diameters liʻiliʻi e like me 0.8mm.
He mea nui e hoʻohālikelike i ka mahana o ka thermistor NTC me ka mahana o ka mea e hoʻololi ai ka mahana.ʻO ka hopena, ʻaʻole i loaʻa wale lākou i ke ʻano kuʻuna me nā alakaʻi, akā hiki ke kau ʻia i loko o kahi hale ʻano screw e hoʻopili ai i ka radiator no ke kau ʻana i luna.
ʻO nā mea hou i ka mākeke he alakaʻi ʻole (chip and component) NTC thermistors i kūpono i nā koi koʻikoʻi o ke kuhikuhi RoSH2 e hiki mai ana.
Palapala noiExampleOʻike maka
Hoʻokomo ʻia nā ʻāpana a me nā ʻōnaehana sensor NTC ma kahi ākea o nā kahua, ʻoi aku hoʻi i ka ʻoihana kaʻa.ʻO nā noi maʻamau nā huila hoʻokele wela a me nā noho, a me nā ʻōnaehana hoʻokele aniau.Hoʻohana ʻia nā Thermistors i nā ʻōnaehana hoʻihoʻi kinoea (EGR), intake manifold (AIM) sensor, a me ka wela a me ka manifold absolute pressure (TMAP).ʻO kā lākou ākea ākea ākea ka hopena kiʻekiʻe a me ka ikaika vibration, hilinaʻi kiʻekiʻe, a me ke ola lōʻihi me ke kūpaʻa lōʻihi.Inā hoʻohana ʻia nā thermistors i nā noi kaʻa, a laila pono ke kūlana koʻikoʻi AEC-Q200 honua ma aneʻi.
I nā kaʻa uila a me nā kaʻa hybrid, hoʻohana ʻia nā mea ʻike NTC no ka palekana o ka pākaukau, ka nānā ʻana i nā wili pulse uila a me ke kūlana hoʻopiʻi.Hoʻopili ʻia ka ʻōnaehana hoʻoheheʻe refrigerant e hoʻomaʻalili i ka pākaukau i ka ʻōnaehana ea.
ʻO ka ʻike wela a me ka hoʻomalu ʻana i nā mea hana hale e uhi i kahi ākea o nā wela.Eia kekahi laʻana, i loko o kahi mea holoi lole, aʻike welahoʻoholo i ka mahana o ka ea wela e kahe ana i loko o ka pahu a me ka mahana o ka ea e kahe ana i waho i kona puka ʻana i ka pahu.No ka hoʻoluʻu a me ka hau, kaNTC sensorana i ka wela i loko o ke keʻena hoʻoluʻu, pale i ka evaporator mai ka maloʻo, a ʻike i ka wela ambient.I nā mea hana liʻiliʻi e like me nā hao, nā mea hana kofe a me nā kīʻaha, hoʻohana ʻia nā mea ʻike wela no ka palekana a me ka pono o ka ikehu.ʻO ka hoʻomehana ʻana, ka ea a me ka ea ea (HVAC) e noho i kahi māhele mākeke nui aʻe.
Ka Uluwehi o ka Lapaau
Aia nā ʻano mea like ʻole o ke kahua uila uila no ka maʻi inpatient, outpatient a me ka mālama home.Hoʻohana ʻia nā thermistors NTC e like me nā ʻāpana ʻike wela i nā mea lapaʻau.
Ke hoʻopiʻi ʻia kahi lāʻau lapaʻau liʻiliʻi liʻiliʻi, pono e nānā mau ʻia ka mahana hana o ka pākaukau rechargeable.ʻO kēia no ka mea, ʻo ka hopena electrochemical i hoʻohana ʻia i ka wā o ka nānā ʻana e hilinaʻi nui ʻia i ka mahana, no laila wikiwiki, pono ka nānā pono ʻana.
Hiki i ka Continuous Glucose Monitoring (GCM) patch ke nānā i ke kiʻekiʻe o ke kō koko i nā poʻe maʻi me ka maʻi diabetes.Maʻaneʻi, hoʻohana ʻia ka sensor NTC e ana i ka mahana, no ka mea hiki ke hoʻopilikia i nā hopena.
Hoʻohana ʻia ka lāʻau ʻo Continuous Positive Positive airway pressure (CPAP) i kahi mīkini e kōkua i ka poʻe me ka apnea hiamoe e hanu maʻalahi i ka wā hiamoe.Pēlā nō, no nā maʻi hanu koʻikoʻi, e like me COVID-19, lawe ka mīkini ventilator i ka hanu o ka mea maʻi ma ke kaomi mālie ʻana i ka ea i loko o ko lākou māmā a me ka wehe ʻana i ke kalapona.Ma nā hihia ʻelua, ua hoʻopili ʻia nā mea ʻike NTC i hoʻopaʻa ʻia i ke aniani i loko o ka humidifier, ka ʻāʻī o ke ea a me ka waha komo e ana i ka mahana o ka ea e hōʻoia i ka ʻoluʻolu o ka poʻe maʻi.
Ua hoʻoikaika ka maʻi maʻi hou i ka pono o ka naʻau a me ka pololei no nā mea ʻike NTC me ka paʻa lōʻihi.Loaʻa i ka mea hōʻike virus hou nā koi hoʻomalu wela e hōʻoia i ka hopena kūlike ma waena o ka laʻana a me ka reagent.Hoʻohui pū ʻia ka smartwatch me kahi ʻōnaehana nānā ʻana i ka wela e aʻo ai i nā maʻi e hiki mai ana.
