Pehea e hoʻokaʻawale ai i ka hoʻohālikelike thermocouple

- 2021-10-19-

Hiki ke hoʻokaʻawale ʻia nā thermocouples i hoʻohana mau ʻia i ʻelua mau ʻano: thermocouples maʻamau a me nā thermocouples non-standard. ʻO ka thermocouple maʻamau i kapa ʻia i ka thermocouple nona ka mana thermoelectric a me ka mahana i hoʻopaʻa ʻia i ka hae aupuni, i ʻae i nā hemahema, a he papa ʻaina kaulike maʻamau. Loaʻa iā ia kahi hiʻohiʻona hiʻohiʻona kaulike no ke koho. ʻO nā thermocouples non-standardized ʻaʻole maikaʻi e like me nā thermocouples maʻamau e pili ana i ka laulā noi a i ʻole ke kauoha o ka nui. ʻO ka maʻamau, ʻaʻohe papa ʻaina kuhikuhi mau, a hoʻohana nui ʻia ia no ke ana ʻana i kekahi mau hanana kūikawā.

ʻO nā thermocouple maʻamau ʻehiku, S, B, E, K, R, J, a me T, he mau thermocouple o ka hoʻolālā kūlike ma Kina.

ʻO ka helu helu helu o nā thermocouple ka nui o S, R, B, N, K, E, J, T a pēlā aku. I kēia manawa, pili ʻo S, R, B i ka thermocouple metala makamae, a ʻo N, K, E, J, T no ka thermocouple metala makamae.

ʻO ka aʻe ka wehewehe o ka helu helu thermocouple
S platinum rhodium 10 maʻemaʻe platinum
R platinum rhodium 13 platinum maʻemaʻe
B platinum rhodium 30 platinum rhodium 6
ʻO K Nickel Chromium Nickel Silicon
T ke keleawe maʻemaʻe keleawe nikela
J nikela keleawe hao
N Ni-Cr-Si Ni-Si
E nickel-chromium keleawe-nickel
(S-type thermocouple) platinum rhodium 10-platinum thermocouple
ʻO ka platinum rhodium 10-platinum thermocouple (S-type thermocouple) he thermocouple metala makamae. Ua kuhikuhi ʻia ke anawaena o ka uea kāne he 0.5mm, a ʻo ka hewa i ʻae ʻia ʻo -0.015mm. ʻO ka haku mele nominal o ka electrode maikaʻi (SP) he platinum-rhodium alloy me 10% rhodium, 90% platinum, a me ka platinum maʻemaʻe no ka electrode maikaʻi ʻole (SN). ʻIke mau ʻia ʻo ka thermocouple platinum rhodium hoʻokahi. ʻO ka mahana hana lōʻihi lōʻihi o kēia thermocouple ʻo 1300℃, a ʻo ka mahana hana kiʻekiʻe o ka wā pōkole he 1600℃.
