Thermocouples cable

Extension Cable : this cable nature is the same as the respective thermocouples conductors. It is show of by an “X” following the thermocouple type.

Compensation Cable : his cable nature is different from the thermocouple. Different alloy could be used for the same type of thermocouple. It is show of by a “C” following the thermocouple type.

Accuracy following certification EN 60584-2 – 07/1993
