Is there any pitfalls in converting (amplifying) analog DC signal from transducer to measurements, except noise
If you have an ADC that gives sufficient resolution (which is a measure that you have to decide on/give us, we can't answer that for you) using only your 0-24mV signal, then this is likely the best option.
The amplifiers which are made by the same manufacturer are likely to work well with their transducer &amp; the isolation sure shouldn't hurt anything.
You could magnify the output voltage using something as simple as an OpAmp voltage multiplier circuit like this one:

(Note that this circuit DOES NOT isolate your ADC from the 24V supply, should the op amp or transducer fail)
