When connecting signals to data acquisition equipment a number of
considerations can be quite important to achieve quality data.
The signals of interest are frequently low-level milli-volt signals
generated by such sensors as thermocouples, strain gages, etc.
Furthermore the sensors are frequently remote to the data
acquisition equipment requiring long cable runs and in some
cases in areas were high levels of electromagnetic interference (EMI)
is encountered. To further
complicate accurate measurements, less than ideal grounding
situations frequently exist.
Proper design and installation of wiring between sensors and
the data acquisition equipment can be an important factor in
obtaining quality data.
