thermocouple.two dissimiler metals joined together it forms
thermocouple.if we apply voltage tn one junction is hot &
another becomes cold Junction.
such Thermocouple generates MV output signal according
to metal characterstics.it gives 0 mv for 0 degree. to
measure actual temperature of the measuring point we should
remove the temp. of measurment envirnment for that the
compansation equals to surrounding temp. is provided and
used as 0mv.
