Analysis and comparison of data from a magnetic field camera and a thermal imaging camera

The research station shown in the photo consists of an IRS336 - NDT camera, a heat source (2x500W halogen lamps), and a desktop computer with IrNDT thermal imaging software installed. A DAQ data acquisition card (NI USB – 6251) is connected to the desktop computer. Additionally, an AT IRXBOX hardware module was installed for hardware triggering of thermogram recording and acquisition of thermal stimulation sources.
The thermal imaging camera is attached to the MagCam magnetic field camera station. This station consists of a magnetic field camera, a table with movable X, Y, Z axes and a desktop computer with software.

Experimental tests were carried out on composite samples made of iron powder mixed with polyvinyl chloride (PVC) in various proportions. The photos show exemplary composite samples with a composition of 75% Fe + 25% PVC (a,b,c) and 25% Fe + 75% PVC (d).

2. composite sample with inclusions of 3 mm thick transformer sheet (b)

3. composite sample with inclusions of 4 mm thick transformer sheet (c)

4. Composite sample with PVC inclusion (d)

As a result of the research, magnetograms and thermogram sequences were obtained, which were used for further analysis.

The gallery presents sample test results of a reference sample and a composite sample with a 4 mm inclusion.
