Welding seam detection sensor (applicable for metal detection and distinguishing between magnetic and non-magnetic materials)
We will detect the welded parts using eddy currents. Since it is eddy current, it can be detected even if surface finishing, mirror finishing, painting, or plating has been applied.
This product is a welding position detection sensor that uses the eddy current method. It detects the welding seam position of magnetic materials moving in the same direction (non-destructive testing). The sensor detects the welding seam as a change in analog voltage, and the detected analog signal is converted into ON/OFF signals for a transistor by a comparator and outputted. (Analog output is also available.) It is not affected by surface treatments (mirror finish, sandblasting, shot blasting, painting, plating, anodizing, etc.), so there is a possibility of detecting workpieces that could not be detected by image sensors (image processing) or laser sensors. Detection is possible for both magnetic and non-magnetic metals, but it may be difficult to detect depending on the size and shape. Therefore, we suggest starting by discussing your needs, borrowing the target workpiece, and exploring the possibility of detection. We will generally respond free of charge regarding the possibility of detection, and if there are costs associated with jigs or other items, we will proceed after obtaining your consent. Please feel free to consult us about integration into inspection lines, improvements, joint development, patents, confidentiality agreements, and more.
