3.13. Cold Junction Terminal
ICJ 104
At temperature measuring via thermocouples the
Datalogger IDL 101
offers the possibility of internal cold junction
compensation. For these purposes a separate terminal strip called
ICJ 104
is available. The
ICJ 104
must be ordered
additionally as a accessory part.
At temperature measuring via thermocouples with internal cold junction compensation the terminal strip for the analog
inputs simply will be replaced with the cold junction compensation terminal strip
ICJ 104
,
which is colored green instead
of the common grey color in order to show the difference. A Pt100-resistance is placed between the terminal SOURCE
and AGND in the
ICJ 104
- terminal strip. Via the resistance thermometer the
Datalogger IDL 101
determines the
terminal temperature and executes the cold junction compensation. Up to 6
ICJ 104
can be connected to one IDL 101.
