3.3.1 Pore water pressure transducers

Pore water pressure transducers, most of them are generally strain gauge type, precisely catch minute fluctuation in pressure with high accuracy. The transducers are mainly used as instruments to measure distributions of pore water pressure in the model ground and to observe the consolidation process during the flight. In case of liquefaction tests, these transducers are essential to locate the liquefied portion and its magnitude.
