Elektrophysik Coating Thickness Gauges

ElektroPhysik

A coating thickness gauge measures the thickness of a coating, such as paint, powder coat or plating, applied over a base material. Elektrophysik gauges, supplied through BTSA, use magnetic or eddy-current principles depending on the base material being coated.

What Is a Coating Thickness Gauge?

A coating thickness gauge measures how thick a protective or decorative layer is without damaging the part, which is essential for quality control in painting, plating and powder-coating processes.

Magnetic vs Eddy-Current Measurement

Magnetic gauges measure non-magnetic coatings, such as paint, on a magnetic base material like steel, using the change in magnetic field caused by the coating layer. Eddy-current gauges measure non-conductive coatings on a non-magnetic conductive base, such as paint on aluminium, using induced electrical currents. The correct method depends on both the coating and the base material.

Applications

Coating thickness gauges are used across automotive body-panel inspection, powder-coating quality control, and general metal-finishing processes where coating thickness affects both appearance and corrosion protection.

Frequently Asked Questions

What is a coating thickness gauge used for?

A coating thickness gauge measures the thickness of a coating, such as paint, powder coat or plating, applied over a base material, without damaging the part. It is widely used in automotive, metal-finishing and powder-coating quality control.

What is the difference between magnetic and eddy-current coating thickness measurement?

Magnetic gauges measure non-magnetic coatings on a magnetic base, such as paint on steel, using changes in magnetic field. Eddy-current gauges measure non-conductive coatings on a non-magnetic conductive base, such as paint on aluminium, using induced electrical currents. The base material determines which method applies.

Can a coating thickness gauge be used on any material?

No. The measuring method must match the base material: magnetic gauges need a magnetic base, and eddy-current gauges need a non-magnetic conductive base. Some gauges combine both methods automatically.
