PR1231/PR1232 Platinum maʻamau-10% Rhodium/Platium Thermocouple

Māhele 1 Nānā

ʻO ka papa mua a me ka papa lua maʻamau platinum-iridium 10-platinum thermocouple i loaʻa ka pololei kiʻekiʻe maikaʻi maikaʻi kino a me nā waiwai kemika, maikaʻi ke kūpaʻa oxidation i nā wela kiʻekiʻe, kūpaʻa maikaʻi a me ka reproducibility o ka ikaika thermoelectromotive.No laila, ua hoʻohana 'ia e like me ka maʻamau ana mea ma (419.527~1084.62) °C, ua hoʻohana 'ia i ka wela magnitude transmit a me ka precision ana ana wela i loko o ke ana wela.

Māhele 2 Nā palena ʻenehana

Helu helu ʻO ka papa mua platinum-iridium 10-platinum thermocouple ʻO ka papa lua platinum-iridium 10-platinum thermocouple
Pono a maikaʻi ʻole ʻO ka mea maikaʻi he platinum-rhodium alloy (platinum 90% rhodium 10%), ʻo ka mea maikaʻi ʻole he platinum maʻemaʻe.
electrode ʻElua mau electrodes anawaena he 0.5-0.015ʻaʻole emi ka lōʻihi o mm ma mua o 1000mm
ʻO nā koi o ka ikaika electromotive wela. E(tCu)=10.575±0.015mVE(tAl)=5.860+0.37 [E(tCu)-10.575]±0.005mVE(tZn)=3.447+0.18 [E(tCu)-10.575]±0.005mV
Paʻa o ka Thermo-electromotive ikaika 3μV 5μV
Ka hoʻololi makahiki Thermo-electromotive ikaika ma Cu point(1084.62 ℃) ≦5μV ≦10μV
Kaulana Mahana Hana 300~1100 ℃
lima hoʻokaʻawale ʻO ke anawaena puka lua (0.8~1.0)mm, ka lōʻihi (500~550)mm.

 

Mahele 3Nā kuhikuhi noi

Pono nā thermocouple platinum-iridium 10-platinum maʻamau e like me ka papa ʻōnaehana hoʻopuka aupuni, pono e hoʻokō ʻia nā kaʻina hana hōʻoia National.Hiki ke ho'ohana 'ia ka papa mua ma'amau platinum-iridium 10-platinum thermocouple e ana i ka papa lua, Ⅰ papa, Ⅱ papa platinum-iridium 10-platinum thermocouple a me Ⅰ papa kumu metala thermocouple;Hiki ke hoʻohana wale ʻia nā thermocouple platinum-iridium 10-platinum papa lua no ke ana ʻana i nā thermocouple metala kumu Ⅱ.

Palapala hōʻoia aupuni Ka inoa hōʻoia aupuni
JJG75-1995 maʻamau platinum-iridium 10-platinum thermocouple kikoʻī calibration
JJG141-2013 Ke hana nei metala makamae thermocouple calibration kiko'ī
JJF1637-2017 kumu metala thermocouple calibration hoakaka

 

Mahele 4 Ka mālama ʻana a me ka mālama ʻana

1. ʻO ka manawa hoʻoponopono thermocouple maʻamau he 1 makahiki, a i kēlā me kēia makahiki e hoʻopili ʻia ka thermocouple maʻamau e ke keʻena metrology.

2. Pono e hana ʻia ka calibration nānā pono e like me ka hoʻohana ʻana.

3. Pono e ho'oma'ema'e ke kaiapuni hana o ka thermocouple ma'amau e pale aku i ka haumia o ka thermocouple ma'amau.

4. Pono e hoʻokomoʻia ka thermocouple maʻamau i kahi kūlana haumiaʻole a paleʻia mai ka pilikia mechanical.

 

Māhele 5 ʻO ka mālama ʻana i ka wā e hoʻohana ai

1. ʻAʻole hiki ke hoʻohana ʻia ka paipu insulation ma ke ʻano wela wela.Hoʻohana ʻia ka paipu insulation kumu ma hope o ka hoʻomaʻemaʻe ʻana a me ka hoʻomoʻa ʻana i ka wela kiʻekiʻe.

2. ʻAʻole nānā ka paipu insulation i ka maikaʻi a me ka maikaʻi ʻole, e hoʻohaumia ʻia ka pou platinum a e emi iho ka waiwai thermoelectric.

3. E hoʻohaumia i ka thermocouple maʻamau ka paipu insulation thermocouple maʻamau me ka uea makamae, a pono e hoʻohana ʻia ka paipu metala pale no ka hōʻoia ʻana i ka thermocouple metala kumu.

4. ʻAʻole hiki ke hoʻokomo koke ʻia ka thermocouple maʻamau i loko o ka umu hoʻoponopono wela, ʻaʻole hoʻi e lawe ʻia mai ka umu hoʻoponopono wela.E pili ana ka wela a me ke anu i ka hana thermoelectric

5. Ma lalo o nā kūlana maʻamau, pono e hoʻokaʻawale ʻia ka umu hōʻoia no ka thermocouple metala makamae a me ka thermocouple metala kumu;inā ʻaʻole hiki ʻole, pono e hoʻokomo ʻia ka paipu seramika maʻemaʻe a i ʻole corundum tube (ka anawaena e pili ana i 15mm) i loko o ka pahu umu no ka pale ʻana i nā Thermocouple metala makamae a me nā thermocouple maʻamau mai ke kumu metala thermocouple pollution.
