Abstract:
A soil probing device comprising a probing rod including a plurality of linkable rod sections, which probing rod, while being pushed into the soil, is extendable each time by one or more rod sections, said soil probing device further comprising a measuring probe which is fitted to the probing rod and is provided with measuring means to obtain data regarding the soil, and said soil probing device further comprising data transmission means which are designed for transmission of data between the measuring probe and a location at or near the soil surface, said data transmission means comprising transmitter means which are located next to or near the measuring probe and are designed for feeding data to an optical guide within the probing rod for the optical transmission of the data to receiver means which are located at or near the soil surface and are designed for receiving data optically transmitted by the transmitter means, wherein each rod section is provided with an optical guide section extending essentially between the ends of the rod section so that linking such rod sections results in the formation of a continuous optical guide within the probing rod.
