Coating Thickness Gauge

A coating thickness gauge is a testing instrument that is used to measure the thickness of a coating that has been connected to a surface. It is also known as a paint meter. To choose a coating thickness gauge, we have to know the substrate first.  Coating thickness estimation could be a principle component in fabricating, particularly for items that depend on dependable coatings for execution or strength. Coating must be connected to correct determinations assigned by the end-users of the item. Deciding the thickness of a coating is critical since it impacts the general product’s life span, execution, and physical appearance.

Moreover, Correct thickness estimates are basis for understanding the coating’s capabilities and quality. High-quality gauges give predominant adaptability for analyzing coating thickness without harming the substrate.

In addition, Ultrasonic thickness gauges are perfect for measuring the impacts of erosion or disintegration on tanks, channels, or any structure. Ultrasonic thickness gauges are designed for measuring the thickness of steel, cast press and aluminum (metallic) and ceramics, plastics and glass(non-metallic) substrates.


Ferrous and nonferrous coating thickness gauges

 are useful for precise measurement of non-conductive coating thickness on magnetic and non-magnetic substrates. Iron is used for coating magnetic material and non-magnetic material. On metallic and non-metallic materials coatings of paint, enamel, rubber, and plastic are applied. A  Paint thickness gauge (paint meter) measures the overall film construct (thickness) of all car paint layers on metal vehicle boards. (Zinc phosphate, primer, base coat color,)are involved in automotive paint layers. Powder thickness gauge provides simple, fast, and accurate coating thickness measurement on smooth and thin industrial paint and powder coatings. Powder coatings producers prescribe target film thickness ranges to realize excellent execution characteristics.

Coating thickness guage Working Principle

The working principles for coating thickness gauge are the Magnetic Induction, Eddy Current, and Ultrasonic Principle.

  1. Magnetic Induction: In this method a magnetic field is used for measuring the thickness of non-magnetic coatings. A magnetic field is generated by the gauge that interacts with the coating. By observing the magnetic field changes, the thickness of the coatings is calculated. 

2. Eddy Current: The thickness of non-conductive coatings applied to conductive surfaces can be measured by using this method. The conductive substrate gets Eddy currents as a result of the gauges alternating current generation. Afterwards, the coating interacts with these Eddy currents and the gauge measures the coating thickness.
