Use of Cu10 sensors
•
Select ”Thermal resistance 3-wire” and ”Cu10” during configuration.
•
Wire the Cu10 sensor in 3-wire connection technology
•
During operation the wire resistance of the missing measuring wire is
automatically compensated internally.
Note
For optimum wire compensation with Cu10 please observe the following:
•
The total of wire resistance and measuring resistance must not exceed 31
Ω
.
•
The resistance of the wire must be a maximum of 8
Ω
if you want to use the
temperature range up to above 312
_
C. Example: A 200 m long Cu cable with
a cross-section of 0.5 mm
2
has about 7
Ω
, a small cross section reduces the
allowable cable length accordingly.
