Temperature data
Temperature resistance for the connecting cable
The temperature at the cable entries of the device is dependent
on the measuring medium temperature T
medium
and the ambient
temperature T
amb.
.
For the electrical connection of the device, use only cables with
sufficient temperature resistance in accordance with the
following table.
T
amb.
Temperature resistance for the connecting cable
≤ 50 °C (≤ 122 °F) ≥ 70 °C (≥ 158 °F)
≤ 60 °C (≤ 140 °F) ≥ 80 °C (≥ 176 °F)
≤ 70 °C (≤ 158 °F) ≥ 90 °C (≥ 194 °F)
From an ambient temperature of T
amb.
≥ 60 °C (≥ 140 °F), the
wires in the connection boxes with the enclosed silicone hoses
need to be additionally insulated.
Note
The signal cable supplied by ABB can be used without
restrictions up to an ambient temperature of ≤ 80 °C (≤ 176 °F).
