Soil probing device with optical data transmission

摘要

A soil probing device comprises a probing rod which is assembled from a plurality of linkable rod sections and, while being pushed into the soil, is extended each time by one or more rod sections. The device further comprises a measuring probe which is fitted to the probing rod to obtain regarding the soil. The device also comprises a data transmitter that is designed for transmission of data between the measuring probe and a location at or near the soil surface. Each rod section is provided with an optical guide section extending between its ends in such a way that linking such rod sections results in the formation of a continuous optical guide within the probing rod.
