The digital D-Cone series represents Geomil Equipment’s latest innovation in Cone Penetration Testing (CPT). Since the introduction of the CPT in 1932, our cones have evolved from mechanical to electrical and now to digital. For over 80 years our equipment has contributed to the successful completion of many challenging projects across the globe.
Drawing on our experience and proven technology the all new, next generation, digital cones are developed in-house. The D-Cone measures the cone resistance (qc) and local sleeve friction (fS) using strain gauged precision load cells. In addition, the dynamic pore water pressure (u) is measured by a piezo element and an accelerometer is used to monitor the inclination in X and Y directions.
The standard offered measuring range is 100 MPa for qc and 1 MPa for fs with additional ranges available on request.
The D-Cone is part of the newly developed Geotechnical Sensor Network (GSN).
