9.2.3 Sensitivity and Response Time
Depending on their type, the available transducers cover a very wide range of pressure
from a few Pascals to several hundred bars for membrane transducers. Their response
ranges from zero (stationary measurement) to approximately 10
5 Hz (see Fig. 9.9).
Whereas active pressure transducers have a measurement range extending from
a few Pascals to several thousands of bars; their frequency range extends from zero
(steady measurements) to almost 10
9 Hz (see Fig. 9.10).
