COATING THICKNESS MEASUREMENT GUIDE The choice of coating thickness gage depends on the type of coating, the shape and type of substrate, the thickness of the coating, the cost of the equipment and the accuracy required. The most commonly used techniques include non-destructive dry film thickness methods such as magnetic, eddy current, and ultrasonic. Wet film thickness measuring equipment is also available for powder and liquid coatings before curing. There are four main types of dry film thickness gauges available - magnetic pull-off, electromagnetic induction, eddy current and ultrasonic. Magnetic gauges are used to measure the thickness of non-magnetic coatings on ferrous substrates such as steel and iron. Magnetic pull-off gauges use a permanent magnet. As the coating thickness increases, the pull off force is reduced and this measurement of force is transferred to a graduated scale from which the coating thickness can be read. Electromagnetic induction instruments use a probe which produces a magnetic field. The magnitude of flux density produced is measured and this measurement is related to the distance between the probe and the metal substrate. The instrument converts the flux density measurement to a paint thickness reading on the instrument display. Eddy current instruments are used to measure the thickness of non-conductive coatings on non-ferrous metal substrates. The instrument probe produces eddy currents on the test surface. The paint thickness and the substrate characteristics affect the magnitude of the eddy currents. The eddy currents create an opposing electromagnetic field and this is measured by the main coil or by a second adjacent coil. Ultrasonic instruments can be used to measure the thickness of coatings on non-metal substrates (plastic, wood, etc). The probe transducer transmits ultrasound through the coating and this sound wave is reflected off the substrate surface and back to the probe. The instrument measures the time interval between the excitation pulse that generates the sound wave and the first returning echo. This time interval between is then converted to a thickness reading on the instrument display.
