WELD SEAM DETECTION ROLAND! sensor technology WELD SEAM DETECTION IN NARROW STEEL STRIPS For magnetizable steels as well as for austenitic stainless steel • Suitable for narrow steel strips Independent of optical surface discolorations Also suitable for start and stop processes Analog outputs 4 to 20 mA or 2 to 10 V for the connection to the PLC • Cost-efficient control unit XA100-S Two different operating frequencies are selectable

• Detects invisible weld seams, very high detection reliability • Weld seam sensor based on eddy current • The system consisting of magnetization unit and eddy current coil can be connected directly to a PLC • With ferromagnetic materials, pre-magnetization increases the process reliability of the system During the continuous processing of narrow gauge steel strips and other long products (such as cable, wires), it is nesessary to detect the joints between individual segments (e.g. strip coils with transverse welds, cable coils with connectors). Materials, such as narrow gauge steel strips, cables...

Supply Connection

The transportation velocity of the strip should not exceed 16.40 ft/s. This implies that the PLC can capture and process the signals at a rate of 5 kHz. If this is not possible, then the control unit XA100 from Roland is available to generate the required output switch signal.
