Measuring Principles

The gauge uses magnetic and eddy current thickness measurement methods. The non-destructive measurement can measure the thickness of magnetic metals (such as steel, iron, alloy steel) and hard magnetic and non-magnetic coatings (such as aluminium, chromium, copper, enamel, rubber, paint, etc.); the thickness of non-conductive coatings (such as enamel paint, plastic, rubber, etc.) of non- magnetic metals (such as copper, aluminum, zinc, tin, etc.).

Magnetic measurement method:

• When the (Fe) probe comes into contact with a metal surface, the magnetic field will be amplified. It then generates a voltage in a second coil (measuring coil). This voltage depends on the distance from the metal surface. If a non-magnetic coating is present, a defined distance results between the probe and the metal surface, and thus a defined coil voltage. This is electronically evaluated and digitally displayed as the coating thickness.

Eddy current measuring method:

• When the (NFe) probe with its alternating field approaches a non-ferrous metal, an alternating current – called the eddy current – is induced in this metal. This produces another electromagnetic alternating field in the opposite direction, weakening the original field. The effect in the probe is a change of inductiveness. By placing the probe in contact with the coating, a defined distance between the probe and the non-ferrous metal results, thus leading to a defined inductivity. This will be electronically evaluated and digitally displayed as the coating thickness.

Operation Instructions

Basic measurement steps

Sample piece surface preparation

• The preparation of the sample surface must comply with the relevant requirements in chapter 11.
• In the process of preparing the sample surface, the temperature on the sample surface should be avoided as much as possible.
• If the surface to be tested is too rough, it will cause measurement errors. Therefore, the sample surface must be exposed to metallic luster and be smooth and oil-free.
• Surface: A flat test surface is preferable. A sample surface with a radius of curvature of less than 30 mm must be tested with a small support ring or a profiled support ring.
• Sample support
  • For heavy sample pieces: no support is required
  • For medium sized pieces: the sample must be placed on a flat, stable surface with no shaking.
• The minimal sample surface thickness must comply with the requirements of Table 3.
• For hard surface layers, the depth of the layer must comply with the requirements of Table 3.
• Coupling:
  • Light samples must be tightly coupled with a strong support. The two coupling surfaces must be flat and smooth, and the amount of coupling agent should not be excessive. The test direction must be perpendicular to the coupling plane.
  • If the sample is a large-area plate, long rod, or bent; even if the weight or thickness are large, the sample piece may be deformed or unstable, this will result in inaccurate test values. Therefore, the sample should be reinforced or supported on the back side of the sample piece.
• The sample surface should not exceed 30 Gauss.

Measurement process
Before measurement, the instrument can be tested with a random test block. The indication error and repeatability should not exceed the requirements of table 1.

Note: the random test block must be measured with a calibrated device.

Measurement procedure

• Insert the probe into the probe input on the device.
• The probe must be placed into the test sample. The probe, sample and operator must now remain perfectly stable and the probe should be as perfectly perpendicular to the sample as possible.
• If the resulting value exceeds the measurable amount, the device will need to be calibrated separately with 5 test pieces.
• The distance between any two indentations or the distance from the centre of any indentation must comply with table 2.

Distance between two indentation centres| Indentation centre distance from the edge of the sample

not less than| not less than

Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law. For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations. If you have any questions, please contact PCE Instruments.
