= Thermocouple
{wiki}
A <thermocouple> uses two different <electrical conductors> and the <Seebeck effect> to infer a measuring-junction <temperature> from a voltage and a known reference <temperature>. The reference material and the reference <temperature> are distinct choices: B specifies the comparison <Seebeck coefficient>, while $T_c$ specifies the lower limit of the <integral>. The two-material experiment in <Seebeck effect> gives the geometry, sign convention, and calibration limitations.
