ThePosiTest DFTseries of gauges step coverings approximately 40 mils (1000 microns) making them ideal for non-destructive dimension of auto paint density on a range electronic thickness gauge of metals. ThePosiTest DFT Ferrousis perfect for dimensions on steel panels, where as thePosiTest DFT Combois offered for measurement needs on both steel as well as aluminum panels.
How is powder coating thickness measured?
Magnetic film gauges are used to nondestructively measure the thickness of a nonmagnetic coating on ferrous substrates. Most coatings on steel and iron are measured this way. Magnetic gauges use one of two principles of operation: magnetic pull-off or magnetic/electromagnetic induction.
Based on the designated application, customized evaluates and probes are readily available that are specifically developed for gauging on steel, aluminum or both sorts of steel. These top quality tools are utilized in all aspects of car manufacturing, fleet examination, and remarketing.
Evaluating with magnetic determines is delicate to surface roughness, curvature, substrate thickness and the make-up of the metal alloy. When gauging the density of paint over non-metal substratums such as plastic as well as fiberglass, an ultrasonic method is made use of. The probe of the instrument has an ultrasonic transducer that sends a pulse through the layer.
- To validate gage calibration, epoxy covered density requirements are readily available with qualification traceable to nationwide standards companies.
- This is genuinely a total paint thickness gauge, for this sort of price point.
- Calibration of coating density assesses will be impacted by the sort of material, the surface as well as the form surface of the metal substratum to be tested.
- Eddy current covering thickness determines appearance as well as operate like electronic magnetic gauges.
- Additionally, no need to alter the probe to determine the paint with the steel or light weight aluminum base.
The pulse reflects back from the substratum to the transducer and is converted into a high frequency electrical signal that is evaluated to identify finishing thickness. In some circumstances, individual layers in a multi-layer system can be determined. To learn more on this sort of measurement, go here. ThePosiTector 6000series of assesses offer similar dimension capabilities with greater precision as well as resolution.

What does a thickness gauge do?
A coating thickness gauge (also referred to as a paint meter) is used to measure dry film thickness. Dry film thickness is probably the most critical measurement in the coatings industry because of its impact on the coating process, quality and cost.
Various probes are offered with gauging ranges up to 25 or 500 mils (625 — 13mm) and also an option of probes to measure different shapes. With +1% accuracy as well as a 0.05 mil (1 micron) resolution, these are amongst one of the most precise tools offered. Added features such as memory and print capacity are also valuable to customers with a desire to log measurement results.
