Eddylab presents a new waterproof eddy-current driver with IP68 protection class.

The new AX-Series in combination with our ultra-robust eddy-current sensors is an entirely waterproof eddy-current system. A customized molding procedure admits subsea operation of the entire system.

The CNC-machined electronic box is sealed with an O-ring. The frontsided connection between eddy-current sensor and housing is achieved with a hermetically sealed LEMO-connection. The M12-connection on the rear side is also IP68 rated and withstands pressures up to 10 bars. The high degree of pressure resistance between the cable and the connector comes with a specialized injection molding process. The injection process crosslinks the cable’s TPE-jacked and the connector to a monolithic unit.

The AX-System is utilized in tidal power plants. These turbines are placed 40m below sea level with a period free of maintenance for five years. The eddy-current sensors measure the deflection curve of the rotating blades. This information serves as a parameter for maximum performance of the turbine.

Michael Reiter, CEO advices: “The application of sensors under water or in a wet process is a demanding task. A leakage is a no-go. Therefor the choice of the appropriate protection class during projecting is essential.”
