Excavation At Sea with PROFINET Encoders

Encoders enable the wear-free detection of rotation on electric winches for the Reimerswaal trailing suction hopper dredger

The automation on the Reimwerswaal must be particularly robust in order to withstand the extreme environmental conditions.

Previously, the rotary encoders on the winches of the Reimerswaal hopper dredger hardly lasted a year due to the extreme stresses they were subject to on the high seas. The Dutch electrical engineering company eL-Tec therefore developed a wear-free solution for detecting cable winch rotation, using Turck’s QR24 robust and contactless inductive encoders. As the Profinet connection is implemented with Turck’s BL20 multiprotocol I/O system, the crew on board can now also replace an encoder themselves.
