E mafai fo'i ona fa'aigoa o uaea fa'ameamea, talu ai e fa'aaogaina mo le fuaina o le vevela. O le faufale e tutusa ma uaea meafaifa'aili fa'alua ae e 'ese'ese mea fa'atonu. Thermocouple e fa'aaogaina i faiga e lagona ai le vevela ma e feso'ota'i i pyrometers mo fa'ailoga ma fa'atonu. O le thermocouple ma le pyrometer e fa'a eletise e ala i uaea fa'alautele thermocouple / uaea tau totogi thermocouple. O ta'ita'i o lo'o fa'aogaina mo nei uaea fa'ato'a e mana'omia le iai o mea fa'atekono-eletise (emf) fa'apei o le thermocouple na fa'aaogaina mo le fa'alogoina o le vevela.
Ituaiga T Thermocouple (Copper + /Constantan– ) T ose laina vaapiapi ma maualuga le sao atoatoa uaea thermocouple. E ta'uta'ua i mea fa'asaienisi ma foma'i e mata'ituina le vevela. E sa'o ± 1°C / 2°F mo tapulaa masani ma ±0.5°C / 1°F mo tapula'a fa'apitoa, ma o lo'o iai le vevela -330°F ~ 662°F (-200°C ~ 350°C) fa'alagolago i luga ole fua ole uaea.
O la matou laau e masani ona gaosia le ituaiga KX, NX, EX, JX, NC, TX, SC / RC, KCA, KCB totogi uaea mo thermocouple, ma o loʻo faʻaaogaina i meafaifaʻaili e fua ai le vevela ma uaea. O a matou oloa faʻatauina thermocouple o loʻo faia uma e tusa ai ma le GB / T 4990-2010 'Uea Alloy o le faʻaopoopoga ma le tauia o uaea mo thermocouple' (Chinese National Standard), ma le IEC584-3 'Thermocouple part 3-compensating wire' (International standard).
O le sui o le comp. uaea: thermocouple code+C/X , eg SC, KX
X: Puupuu mo le faʻaopoopoga, o lona uiga o le uaea taui e tutusa ma le faʻaogaina o le thermocouple.
C: Puupuu mo taui, o lona uiga o le uaea taui e iai uiga tutusa ma le u'amea a le thermocouple i se vaega o le vevela.
Talosaga:
1. Fa'avevela - Fa'amu kasa mo ogaumu
2. Fa'alili - Fa'aaisa
3. Puipuiga o le afi - Temperature ma le vevela o luga
4. Pulea maualuga o le vevela - Umea lafo
