Dial-Type Magnetic Induction Thickness Gauge

The pointer-type magnetic resistance thickness gauge measures coating thickness by detecting changes in magnetic resistance when the probe contacts the metal substrate, which drives the pointer to display the reading. It is used to measure non-conductive coatings on ferrous materials, such as paint or plastic. During operation, ensure the substrate is flat and avoid interference from strong magnetic fields.
Selection
When selecting, consider the magnetic permeability of the substrate; iron-based materials are suitable. The measurement range should cover the sample thickness, and the accuracy must meet process requirements. The probe size should match the shape of the workpiece, and regular calibration with standard shims is necessary. The environment should be free from vibration and corrosive gases.
