Type
J (Iron vs. Constantan)
Can be used protected or unprotected. Reducing
atmosphere recommended. Iron wire oxidizes rapidly above
1000 F.
Type K
(Chromel-Alumel*)
Recommended for ixidizing atmospheres. Should be
used in suitable protection tube when in a reducing or
sulfurous atmosphere.
Type T
(Copper-Constantan)
Useable in oxidizing, reducing or inert
atmospheres.
Type E
(Chromel*-Constantan)
Oxidizing atmospheres recommended. Highest EMF of
common base metal thermocouples. |
Type
R (Platinum vs. Platinum 13% Rhodium)
Oxidizning atmosphere recommended. Should be protected with
ceramic protection tube. Higher EMF output than Type S.
Type S (Platinum
vs. Platinum 10% Rhodium)
Same general conditions as Type R
Type B (Platinum 6% Rodium vs. Platinum 13%
Rhodium)
Same general conditions as Type R adn S. EMF output is lower
than Type R and S.
Type N (Nicrosil
vs. Nisil)
For general use, better resistance to oxidation and
sulfur than Type K. |
