what do you mean by CJC (cold junction compensation).?
Answer Posted / balajirajgopal
i assume u asked for thermocouple .as per seeback effect 2
junctions of the thermocouple should be maintained at
different temperature i.e. hot junction in high temp and
cold jn at zero degree temp.but in practical application it
is difficult to maintain cold jn at 0deg C .so a thermister
is placed in the location where the cold jn. is kept.the o/p
of thermister is used to measure the temp at that location
and is used in calculation to neglect the the effect of temp
at cold jn.
pls dont ask me the calculation,bcause i am also searching
for it.
