Measurement Principle

The GoldScreenSensor utilises the eddy current measurement for its measurement principle.
Every metal exhibits a characteristic conductance value (unit: Megasiemens per meter [MS/m]),
which enables the identification of falsifications or an under-alloying. Due to similar densities,
the most used metals for falsifications like tungsten, lead or tantalum usually differ significantly
in their conductivity compared to precious metals or gold alloys.
The inductive testing method uses electromagnetic alternating fields, whose penetration depth
depends on the applied frequency and the electrical conductance of the testing sample. The
penetration depth of the GoldScreenSensor go beyond the thickness of the metal layers that
normally have been applied by chemical means or by electroplating and range from
approximately 250 µm (pure silver, highest conductance), 350 µm for pure gold (middle
conductivity range) and up to 650 µm (gold alloys, e.g. Krugerrand, lower conductivity range).
The whole sensor as well as the electronic unit is situated inside the compact casing of the
battery-powered device allowing the use of the GoldScreenSensor as a mobile device.
