The autarchic weld seam sensor for narrow metal strips up to 30 mm (1.18 in) of width, preferably for magnetisable steels or stainless steels with delta-ferrite in the weld seam. In combination with the cost-effective control unit XA100, this sensor represents a good solution for the small machine.
The Roland Company has now developed a new weld seam detector based on the eddy current principle for these type of semi-finished steel strips.
The system consists of a magnetizing unit and an eddy current encircling coil sensor that can be directly connected to the PLC. The orifice of the encircling coil is suitable for material with the dimensions 40mm x 8 mm (1.575 in x 0.315 in).
In ferromagnetic materials, the premagnetization increases the process reliability ofthe system.
| Applications: | Processing of narrow gauge steel strips and other long products (such as cable, wires); wherever it is necessary to detect the joints between individual segments (eg, strip coils with transverse welds, cable coils with connectors) |
| Material type and thickness: |
Carbon steel: 0,2 mm … 4 mm (0.008 in ... 0.158 in), Non-magnetic stainless steel: 0,5 mm … 4 mm (0.012 in ... 0.158 in), Aluminum: 0,5 mm … 4 mm (0.012 in ... 0.158 in) |
| Measuring method: | Eddy current - Encircling coil |
| Functional principle: | Weld Seam Detection, such as narrow gauge steel strips, cables and wires are fed through the eddy current encircling coil and transported continuously during the measurement process. The sensor detects the weld seam at stand-still as well as during continuous transportation. |
| Strip width: | 5 mm … 30 mm (0.916 in ... 1.180 in) |
| Control unit: | XA100 |
| Environmental temperature: |
+10°C bis +40°C (+50°F to +104°F) |
| Weight: | 7 kg (15 lb) |
