Magnetic Induction Paint Film Thickness Gauge

The magnetic induction coating thickness gauge generates a magnetic field through its probe. When the probe approaches a ferrous substrate, the magnetic flux changes, and variations in the thickness of non-ferromagnetic coatings lead to differences in magnetic reluctance. The instrument calculates the coating thickness by measuring these differences. It is used for detecting the thickness of coatings such as paint and plastic on ferrous substrates and is commonly employed in on-site quality inspections in industries such as automotive and steel structures.
Selection
When selecting, confirm that the substrate is magnetic metal, the measurement range covers the thickness of the coating to be tested, and the ambient temperature meets operational requirements. The probe size must match the shape of the test piece, and consider whether the instrument error meets the standard. Portable types are suitable for on-site use, while fixed types are suitable for production lines. Verify the calibration certificate and protection rating.
