Why you need to Calibrate a Coating Thickness Gauge before testing?
Calibration of coating thickness gauges will be affected by the
type of material, the shape and the surface finish of the metal
substrate to be tested.
For example the magnetic properties of steel alloys vary and the
conductivity of different aluminium alloys and different
non-ferrous metals, copper, brass, stainless steel etc. also vary.
These variations can affect the linearity of a coating thickness
gauge. This means that a gauge set-up on mild steel for example
will read a different value for the same thickness coating on high
carbon steel. Similar linearity effects are seen on thin or curved
substrates and particularly on profiled substrates such as blast
cleaned steel used for structural steelworks.
To overcome these effects most coating thickness gauges have
features that allow you to set the gauge to the work being carried
out, thus maximising the accuracy of the readings.
Adjusting a Coating Thickness Gauge
Adjustment is the technique whereby you can set-up the coating
thickness gauge for the conditions prevailing for the work in hand.
In addition to material differences, shape and surface finish the
adjustment may be carried out at an elevated temperature or in the
presence of a stray magnetic field. By adjusting the coating
thickness gauge to these prevailing conditions the resulting errors
are greatly reduced and even eliminated.
The effect of surface roughness, particularly that produced by
deliberately profiling the substrate by blast cleaning with either
grit or shot or by mechanical cleaning, is quite significant.
