What is cold junction compensation in thermocouples? How is
it achieved?
Answer Posted / vinoth.s
TC works on the principle of SEEBACK's Effect, which states
the the temperature difference is directly proportional to
induced emf, when two dissimilar metals are twisted together
and heated at end.
its equation states,
hot junction - cold junction = induced emf.
its means hot junction is the temperature measured..
cold junction means the ambient temperature unlessly
considering the compensation. we have keep the cold junction
as constant by giving a constant hot source or ice bath. so
that its easy to find the hot junction values.
