Temperature resistance for the connecting cable
The temperature at the cable entries of the device depends on
the design, the measuring medium temperature T
medium
and the
ambient temperature T
amb.
.
For the electric connection of the device, use only cables with
sufficient temperature resistance in accordance with the
following table.
