About Multivoid tubing

Air conditioner tubing is inspected inline after extrusion. An encircling coil tests for outer surface defects and checks that the walls of the interior chambers are intact. It is specially designed for this tube shape.The eddy current signals are transmitted to an eddy current inspection unit that analyzes the signals for defects. The unit also controls marking of the defects and sorting of the test piece. Test results can be printed out immediately or stored for future reference.

Radiator tubing


Radiator tubing is inspected inline after welding using an eddy current probe.The eddy current signals are transmitted to an eddy current inspection unit that analyzes the signals for defects. The unit also controls marking of the defects and sorting of the test piece. Test results can be printed out immediately or stored for future reference.

Reated Projects

Double-wall brazed tubing

  • Detects critical defects: Finds typical processing defects such as flaws in the inner and outer seam, copper spots and runs
  • Inline inspection: Immediate test results and feed

Sheathed products

Eddy current technology can be used to detect splices, connecting wedges or joint inside coated material such as steel tubes with PVC insulation. In this example, an EDDYSENSOR and an e

Hot rolled copper rod

  • Ferrous inclusion detection: A specially designed FERROCHEK module detects ferrous inclusions in the copper
  • Rolling defect detection: Simultaneous identification of laps, crac

Inline testing

  • Input control: Identification of bad quality material, e.g. rolled wire (drawing lines for thick wire), bar, tube or pipe
  • Quality control: Detection of defective areas in tes
