film thickness needs to be using some simple mathematical formulae:
- Wet Film Thickness.
- =
- Dry Film Thickness x 100.
- % Volume Solids.
- Spreading Rate (m2/litre) =
- % Volume Solids x 10.
- DFT Required.
How is plating thickness measured?
The plating thickness is determined by the amount of magnetic flux that the probe passes through the non-ferromagnetic plating and flows into the ferromagnetic metal substrate.
How is eddy current measured?
Direct measuring of eddy currents is simply impractical. Yes, you can attach electrodes to the media, where you excite currents, and measure the current directly. This will be called a transformer. Measuring eddy currents is a special area of NDT.

| Micrometers (um) | Millimeters (mm) | Mils (Thousandths) |
|---|---|---|
| 25.4 | 0.025 | 1 |
| 50.8 | 0.051 | 2 |
| 76.2 | 0.076 | 3 |

How is coating calculated?
For example, if a coating were 45% solids by volume, its theoretical coverage would be 1604 X 0.45 or 722 square feet at 1 mil dry film thickness. If a specification called for a dry film thickness of 2 mils, the theoretical coverage would then be 722 square feet divided by 2 mils, or 361 square feet per gallon.
What is a coating thickness gauge?
Coating thickness gauges (also referred to as a paint meter) are used to measure dry film thickness. The Elcometer range of dry film thickness gauges (DFT gauge), provide reliable and accurate coating thickness measurements on almost any metal substrate, whether ferrous or non-ferrous.
Where eddy current testing is used?
Applications. The two major applications of eddy current testing are surface inspection and tubing inspections. Surface inspection is used extensively in the aerospace industry, but also in the petrochemical industry. The technique is very sensitive and can detect tight cracks.
What is mils in paint thickness?
1 mil is equal to 1 one-thousandth of an inch (25 microns). The mil thickness of a coating not only effects the appearance of a coating but also the performance and protective qualities. A coating with a mil thickness that is too thin may have less than 100% coverage leaving the substrate vulnerable to corrosion.

How do you measure coating thickness?
Total Thickness – Carrier Material Thickness = Coating Thickness. The gauge can easily measure the total thickness of the material. In some cases, it is possible to measure the substrate or carrier material, but in others it is not due to the production set up.
What is an eddy current sensor?
Eddy-Current sensors are also called inductive sensors, but generally “eddy current” refers to precision displacement instruments (or nondestructive testing probes) and “inductive” refers to inexpensive proximity switches.
How do you measure steel thickness?
The most precise way to measure a metal’s thickness is to use a caliper. Calipers are hand tools designed to precisely measure the distance between two points. Just fit the two tips of the caliper around the metal you need to measure to determine its thickness.
