The High-Pressure Dilatometer (HPD) is the largest pressuremeter at ?95mm OD. This probe also has the highest available maximum pressure and as such can be used in materials ranging from rock, such as mudstone or chalk, to very weak clays.

The 95mm HPD is a pre-bored pressuremeter, so can only be inserted into ‘pockets’ of between 1.5 – 3.0m length, and nominally of between 98 – 101mm Diameter. A common choice for pre-boring (creating a ‘pocket’ for the instrument) is by utilising a 3m T6101 core barrel.

This instrument can be configured to include a digital electronic compass measuring and recording magnetic field. This can allow some insight to the anisotropy of the data collected during a test.

• Insitu direct strain measuring

• 95mm diameter (requires pocket diamter 98-102mm)

• 20mm arm expansion (42.1% strain)

• 20MPa working pressure

• Ideal for soils, sand and rock

• Deploy in pre-bored or cored pocket
