ʻO Semicon hou a me nā mea uila kumu LM50CIM3X/NOPBIC CHIPS mau kaapuni i hoʻohui ʻia i loko o ka waihona.

wehewehe pōkole:

ʻO nā hāmeʻa LM50 a me LM50-Q1 nā mea ʻike wela i hoʻohui ʻia-kaapuni kūpono i hiki ke ʻike i kahi pae wela -40 ° C a 125 ° C me ka hoʻohana ʻana i hoʻokahi lako kūpono.ʻO ka puʻuwai hoʻopuka o ka hāmeʻa he laina laina i ka mahana (10 mV/°C) a he DC offset o 500 mV.Hāʻawi ka offset i ka heluhelu ʻana i nā wela maikaʻi ʻole me ka ʻole o ka lako pono ʻole.
ʻO ka puʻuwai hoʻopuka maikaʻi loa o ka LM50 a i ʻole LM50-Q1 mai ka 100 mV a i ka 1.75 V no ka pae wela -40°C a 125°C.ʻAʻole koi ka LM50 a me LM50-Q1 i ka calibration waho a i ʻole ka ʻoki ʻana e hāʻawi i ka pololei o ± 3°C ma ka lumi wela a me ± 4°C ma luna o ka piha piha –40°C a 125°C.ʻO ka ʻoki ʻana a me ka calibration o ka LM50 a me LM50-Q1 ma ka pae wafer e hōʻoia i ke kumu kūʻai haʻahaʻa a me ka pololei kiʻekiʻe.
ʻO ka hua laina laina, 500 mV offset, a me ka calibration hale hana o ka LM50 a me LM50-Q1 e hoʻomaʻamaʻa i nā koi kaapuni ma kahi wahi lako hoʻokahi kahi e pono ai ka heluhelu ʻana i nā wela maikaʻi ʻole.
Ma muli o ka emi o ka LM50 a me LM50-Q1 i ka 130 µA, ua kaupalena ʻia ka hoʻomehana ʻana iho i kahi haʻahaʻa haʻahaʻa 0.2°C i ka ea.

mea ike?

1. He aha ka mea ʻike?Nā ʻano mea ʻike?Ka ʻokoʻa ma waena o nā mea ʻike analog a me nā kikohoʻe?
ʻO nā sensors nā mea maʻamau i hoʻohana ʻia e ʻike i nā loli i ke kūlana kino a me ka helu ʻana i nā hopena o nā ana ma kahi kikoʻī a i ʻole ka laulā.ʻO ka mea maʻamau, hiki ke hoʻokaʻawale ʻia nā mea ʻike i ʻelua mau ʻano: nā mea ʻike analog a me nā kikohoʻe.Hoʻohana nā mea ʻike wela me nā huaʻōlelo analog i kahi huaʻōlelo analog e hoʻouna i ka mahana, ʻoiai ʻaʻole pono nā mea ʻike me nā puka kikohoʻe i ka reprogramming o ka ʻōnaehana a hiki ke hoʻouna pololei i kahi wela i hoʻoholo ʻia.

mea ike analog?

2.He aha ka mea ʻike analog?He aha ka mea i hoʻohana ʻia e hōʻike i ka nui o ka ʻāpana?
Hoʻopuka nā mea ʻike analog i kahi hōʻailona hoʻomau a hoʻohana i ka volta, ka manawa, ke kū'ē, a me nā mea ʻē aʻe e hōʻike i ka nui o ka ʻāpana e ana ʻia.No ka laʻana, nā mea ʻike wela, nā mea ʻike kaomi, a me nā mea ʻē aʻe he mau mea ʻike analog maʻamau.No ka laʻana, ʻo nā mea LM50 a me LM50-Q1 nā mea ʻike wela i hoʻohui ʻia i hiki ke ʻike i kahi pae wela -40°C a 125°C me ka hoʻohana ʻana i kahi lako maikaʻi.ʻO ka puʻuwai hoʻopuka maikaʻi loa o ka LM50 a i ʻole LM50-Q1 mai ka 100 mV a i ka 1.75 V no ka pae wela -40°C a 125°C.
ʻIke ʻia kahi mea ʻike analog maʻamau i kahi ʻāpana kūwaho, e like me ke kaomi, kani, a i ʻole ka wela, a hāʻawi i ka volta analog a i ʻole nā ​​​​mea hoʻopuka o kēia manawa e like me kona waiwai i ana ʻia.Hoʻouna ʻia ka waiwai hoʻopuka mai ka mea ʻike ana i kahi kāleka analog e heluhelu ana i ka hāpana ana a hoʻololi iā ia i kahi hōʻike binary kikohoʻe hiki ke hoʻohana ʻia e ka PLC/controller.
No nā mea ʻike analog, pono paha e calibrate i ka loaʻa DC a hoʻopau i ka hoʻokō pono ʻana o ka ʻōnaehana pono.ʻAʻole hōʻoiaʻiʻo ʻia ka pololei o ka wela o ka ʻōnaehana ma ka pepa ʻikepili no ka mea e hilinaʻi nui ia i ka hewa kuhikuhi DC.ʻO ka puʻuwai hoʻopuka o ka hāmeʻa he laina laina i ka mahana (10 mV/°C) a he DC offset o 500 mV.Hāʻawi ka offset i ka heluhelu ʻana i nā wela maikaʻi ʻole me ka ʻole o ka lako pono ʻole.

Wehewehe?

ʻO ka wehewehe ʻana i ka ʻike wela?
ʻO ka mea ʻike wela he mea ʻike e ʻike i ka mahana a hoʻololi iā ia i hōʻailona puka hoʻohana.ʻO nā mea ʻike wela ka ʻāpana nui o nā mea ana wela a hele mai i nā ʻano ʻano like ʻole.He pololei loa nā mea ʻike wela no ke ana ʻana i ka mahana ambient a hoʻohana nui ʻia i ka mahiʻai, ʻoihana, hale hana, hale kūʻai, a me nā māla ʻē aʻe.

Hoʻokaʻawale

Hoʻokaʻawale ʻike wela
Hiki ke hoʻokaʻawale nui ʻia ke ʻano o ka hōʻailona puka ʻana i ka wela i ʻekolu mau ʻāpana: nā mea ʻike wela kikohoʻe, nā ʻike wela hoʻoheheʻe loiloi, a me nā mea ʻike wela analog.

Nā pono

ʻO nā pōmaikaʻi o nā ʻāpana sensor wela analog.
Analog wela sensors, e like me thermocouples, thermistors, a me RTDs no ka ana wela, ma kekahi mau wela laina laina, 'aʻole maikaʻi, ka pono no ka anu-hopena uku a alakai uku;thermal inertia, lohi ka manawa pane.Hoʻohui pū ʻia nā mea ʻike wela analog i nā pono o ke kiʻekiʻe sensitivity, linearity maikaʻi, a me ka manawa pane wikiwiki i hoʻohālikelike ʻia me lākou, a hoʻohui pū i ke kaʻa kaʻa kaʻa, kaʻapuni kaʻina hana hōʻailona, ​​​​a me ke kaapuni pono logic control ma kahi IC hoʻokahi, nona nā pono o liʻiliʻi kūpono a me ka maʻalahi o ka hoʻohana.

Palapala noi

Nā wahi noi o nā mea ʻike analog
He ākea loa ka hoʻohana ʻana i nā sensor analog, inā paha, ma ka ʻoihana, ka mahiʻai, ke kūkulu ʻana i ka pale aupuni, a i ʻole ke ola o kēlā me kēia lā, ka hoʻonaʻauao a me ka noiʻi ʻepekema, a me nā ʻano ʻē aʻe, hiki ke ʻike ʻia ke kiʻi o nā sensor analog ma nā wahi āpau.
