Comparisons of Different Transducers

In general, electric transducers are more accurate than pneumatic transducers, while pneumatic transducers, in turn, are more accurate than mechanical transducers. Typical accuracy of electric transducers is 0.5 to 1.0%, pneumatic transducers about 1.5%, and mechanical transducers about 3% [4]. 

The reproducibility for electric systems is about 0.1 to 0.2%, for pneumatic systems about 0.5%, and about 1 to 2% for mechanical pressure transducers. The hysteresis with electric pneumatic transducers is about 0.1 to 0.2%, while it is as high as 4 to 5% with mechanical systems.
