Inductive Thickness Gauge Tool

The induction thickness gauge utilizes the principle of electromagnetic induction. The probe generates an alternating magnetic field, and when it approaches a metal substrate, the eddy current effect alters the probe's impedance. By measuring this change, the thickness of the coating or film is calculated. It is used for non-contact thickness measurement of coatings, electroplated layers, plastic films, etc., on metal surfaces, enabling rapid on-site measurements in industries such as automotive, electronics, and packaging.
Selection
When selecting, consider the base metal type and curvature: use magnetic induction principle for ferrous metals and eddy current principle for non-ferrous metals. Choose the model based on the measurement range, with the standard 0-5mm range meeting most needs. Check the accuracy of ±1-3% and resolution of 0.1μm. Pay attention to the probe size to match the shape of the measurement surface; use a small probe for curved surfaces. Environmental temperature affects stability, so opt for heat-resistant models in high-temperature conditions. Ensure it includes base material calibration functionality and data output interfaces.

Application of Coating Thickness Gauges in Electroplating Thickness Detection
Coating thickness gauges are used to measure the thickness of electroplated layers, primarily employing the electromagnetic induction method for measuring non-magnetic coatings on magnetic substrates, or the eddy current method for measuring insulating coatings on non-magnetic metal substrates.
Eddy current thickness gauge measures metal coatings on non-conductive substrates.
The eddy current thickness gauge utilizes the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil to induce eddy currents in the metal coating, thereby measuring thickness based on changes in coil impedance.
Magnetic thickness gauge measures the thickness of coatings on steel surfaces.
Magnetic thickness gauges are used to measure the thickness of non-magnetic coatings on ferromagnetic substrates such as steel, based on the principles of magnetic induction or changes in magnetic attraction. Prior to use, calibration should be performed according to relevant standards, and attention should be paid to factors such as substrate characteristics, workpiece shape, and surface conditions that may affect the measurements.
