Soil Pressure Gauges

KDA-PA/KDB-PA Soil Pressure Gauge 200kPa to 2MPaCE

These are 200-mm outer diameter soil pressure gauges widely used at construction sites. 
They are designed with a dual-diaphragm structure that can minimize the displacement of the sensing surface when pressure is applied, and thereby keep the stress distribution in the soil undisturbed. KDA-PA and KDB-PA models are available with differing cable exit directions, with KDA-PA used to measure pressure in soil and monitor the behavior of embankments, and KDB-PA used to measure pressure in earth-retaining walls and soil pressure on walls of structures.

KDC-PA/KDD-PA Soil Pressure Gauge 200kPa to 2MPaCE

These are corrosion-resistant all-stainless steel soil pressure gauges each 100 mm in outer diameter. They also allow soil pressure in ocean and coastal civil engineering structures, and also allow measurement of the dynamic pressure of waves. KDC-PA and KDD-PA models are available with differing cable exit directions.

KDE-PA/KDF-PA Soil Pressure Gauge 200kPa to 2MPaCE

These are soil pressure gauges each 50 mm in outer diameter. They are small in size and have a dual diaphragm structure, so they are widely used to conduct model experiments. KDE-PA and KDF-PA models are available with differing cable exit directions.
