The DensX is a high accurate in situ mud density
measurement system. It measures mud
densities between 1.0 T/m³ and 1.5 T/m³ with an accuracy of 0.25 %. The
technology is based on X-ray and is a direct measurement method. With a
sampling speed of 10 Hz the system supports fast profiling. The X-ray
technology does not suffer from strong legislation restrictions like radioactive
density measurement systems. The system weighs 70 kg and is able to deeply intrude
in soft sediment layers.
Along with the DensX comes
a user friendly software that controls a fully automated winch. The software
visualizes the density profile, the winch speed, the winch torque and the tilt
of the DensX. When several density profiles are taken, the software
generates a mud grid and interpolated dredging volume.
Today the DensX is
applied in ports and access channels to characterize mud layers, to measure
density based nautical bottom criteria and to prepare and evaluate dredging
works. The accurate density measurement capability allows to determine
precisely the ton dry weight of dredging material.
The DensX completes dotOcean’s product portfolio of
underwater sediment characterization profilers and is complementary to
rheological instruments as the GraviProbe.
