What is it? |
|
|
|
The GDS Mid Plane Pore Pressure probe
provides a direct measurement of the specimen pore pressure at the
mid height of the sample. The GDS Mid Plane Suction Probe is a
similar device but uses a high air entry porous disk in the tip to
enable suction measurements to be made for unsaturated soil testing. |

| What are its
uses |
| |
Mid-plane pore pressure measurement is preferred to measurements
made in the area of the base pedestal. The reason for this is due to
the minimal volume change of pore fluid
required to activate the transducer diaphragm compared to that in a
base pedestal transducer. |
