Thickness Measurements

The requirement for accurate thickness measurements is found across many industries including aerospace, oil and gas, pharmaceutical and food processing.  Either for quality control in manufacturing or in-service verification often access is only available from one side and speed is critical.  The wall thickness from most materials can be measured ultrasonically including metals, composites, plastics and glass using a simple hand-held digital gauge.

 

In certain environments, a coating of paint or other non-metallic material may have been applied to protect the part.  A common application would be a painted pipe used in the petrochemical industry.  In this case a conventional ultrasonic gauge would give measurement errors from the presence of the paint.  However, with the correct gauge with through paint mode, measurement through the paint is possible resulting in the correct wall thickness measurement underneath.

 

Nomo Group offers a range of standard and high-resolution thickness gauges with features including A-trace display, B-scan, automatic probe recognition, data logging and much more.
