The SND40 is ideally designed to provide a good quality performance and functionality for very specific purposes. It highly provides an ultra-high reliability in Weld Seam Detectionand. Due to the advantage incorporated within the device lies in the combination of magnetic leakage flux and eddy current technology, the user may operate all kinds of metals and can be expected even at cold drawn or heat treated materials a remarkable dependability. The latest SND40 unit is considered as the first PC based technology of its kind. It is combined with the strengths of analog sensor principles and digital signal analysis for weld seam detection. The high quality device is also integrated with a touchscreen capacity feature to enhance the unit's operational capabilities.
