<p>The rod has rod elements provided with energy- and/or data lines connected with an inner induction coil (100) and an outer induction coil. The induction coils are inductively coupled with each other for transfer of data e.g. pressure value, along the rod. The inner induction coil is provided at external circumference of an inner pipe. The outer induction coil is provided at internal circumference of an outer pipe. The induction coils are formed of ring segment parts and overlap in sections along radial direction. The inner pipe is designed as one of rinsing pipe, concrete pipe and double pipe.</p> |
