Installation of temperature sensors
To avoid noise in the Pt100 sensor signals, which may
cause errors in temperature readings, the following
precautions should be taken when installing these
equipment:
The connecting cables must be shielded and the shield
must be grounded;
The installation of the signal cables should be done in a
linear manner, avoiding turns and should not be
installed near of the power cables.
The cables connection must be tightened to prevent
poor contact or loose.
It is recommended that reading the temperature signal of
the Pt100 by specific instruments for temperature
acquisition in electric machines, as these instruments have
filters capable of eliminate the inherent noise of the
application.
