HIGH ACCCURACY DILATOMETER
COMPATIBLE WITH DEEP BOREHOLE
USER-FRIENDLY TABLET-OPERATED READOUT
The DMPe Borehole – or Flexible – Dilatometer equipment is designed for the in situ determination of the deformation modulus of rock masses in 96 mm or 101 mm boreholes
The DMPe Dilatometer consists of a probe with a metal central body. The probe includes:
The probe is read with the D/P BOX Readout which is operated with an Android tablet (see datasheet D/P BOX for more details). A dedicated application, allows configuring the tests and calibrations, displaying and plotting the test results in real-time, logging the data.
The dilatometer probe is designed to be lowered down into the borehole using a string of rods. Nitrogen compressed dry gas is used for pressurizing the probe.
The borehole dilatometer test consists in loading the rock in progressive pressure steps and measuring the diametrical deformation resulting from this loading.
The test is used for generating the following parameters:
