ʻO ka paʻa a me ka pololei o ka mahana CJ he mea nui i ke ana ʻana o nā thermocouples kiʻekiʻe.Pono e hui pū ʻia nā mika kikohoʻe kiʻekiʻe maʻamau me nā lako uku CJ kūikawā no ke ana thermocouple.Hoʻohui ʻia ka module uku uku CJ i hoʻolaʻa ʻia i nā thermometers PR293 series, no laila hiki ke ʻike ʻia ka hewa CJ o ke kahawai hoʻohana ʻoi aku ka maikaʻi ma mua o 0.15 ℃ me nā peripheral ʻē aʻe.

 

Nā hana metrology waiwai nui

ʻO PR291/PR293 series thermometers kahi mea hoʻāʻo kūikawā i hana ʻia no ka ʻoihana metrology wela.ʻEkolu mau ʻano hana o ka loaʻa ʻana, ka hoʻopaʻa ʻana i ke ala hoʻokahi, a me ke ana ʻokoʻa o ka mahana, ma waena o ke ʻano o ke ana ʻokoʻa wela e hiki ke hoʻopaʻa ʻia i ka like ʻana o ka mahana o nā ʻano mea wela mau.

Hoʻohālikelike ʻia me ka multimeter kikohoʻe kuʻuna, ua hoʻohui ʻia kahi ʻāpana 30mV no ke ana ʻana i nā thermocouple S-type a me kahi ākea 400Ω no ke ana kūʻē platinum PT100.A me nā polokalamu hoʻololi i kūkulu ʻia no nā ʻenekini wela like ʻole, hiki ke kākoʻo ʻia nā ʻano ʻike like ʻole (e like me nā thermocouples maʻamau, nā thermometers pale platinum maʻamau, nā thermometers pale platinum ʻoihana a me nā thermocouple hana) hiki ke kākoʻo ʻia, a hiki ke kuhikuhi ʻia ka ʻikepili palapala a i ʻole ka hoʻoponopono ʻana i ka ʻikepili. ka wela o na hopena hoao.

 

Hana ʻikepili ʻikepili

Ma waho aʻe o nā ʻikepili hoʻāʻo like ʻole, hiki ke hōʻike ʻia nā pihi a me ka mālama ʻana i ka ʻikepili, ka nui o ka ʻikepili i ka manawa maoli / ka liʻiliʻi / ka nui o ka nui, hiki ke helu ʻia ke ʻano o ka ʻikepili kūpaʻa wela, a hiki ke hōʻailona ʻia ka ʻikepili kiʻekiʻe a me ka liʻiliʻi e hoʻomaʻamaʻa i ka ʻikepili intuitive. ma ke kahua hoao.
