Magnetic Induction Thickness Gauge

The magnetic thickness gauge measures the thickness of non-magnetic coatings by detecting changes in magnetic flux between the probe and the substrate. The probe contacts the coating surface, and magnetic resistance varies with the thickness of the coating. The instrument converts these signals into thickness values. It is used to measure the thickness of paint, plastic, or galvanized layers on steel substrates, ensuring coating uniformity.
Selection
When selecting, consider the shape of the substrate: use a single probe for flat surfaces and a small probe for curved surfaces. The measurement range should cover the expected thickness, with an error of less than ±3%. Environmental adaptation: choose a waterproof model for humid environments and a heat-resistant probe for high-temperature settings. Operational requirements: use a handheld device for routine inspections and a fixed installation for automated production lines. The degree of probe wear affects accuracy, so regular calibration with a standard calibration piece is necessary.
