How does
ultrasonic thickness measurement work?
The Ultrasonic Thickness Gauge works by sending a short
pulse of high frequency sound through the material being measured. The
thickness gauge then measures the time taken for an echo to be received from
the back wall. With this data, the thickness of the material is determined.
To suit a wide variety of material testing applications,
Cygnus Instruments employ three measuring modes:
Multiple
Echo Measuring Mode (developed & pioneered by Cygnus Instruments)
Give error-checked, accurate metal thickness measurements through coatings upto
20mm thick.
Echo-Echo
Measuring Mode
Measure through paint (max 0.5mm), ideal for testing painted metals with heavy
back wall corrosion or pitting.
Single-Echo
Measuring Mode
For checking uncoated materials; metals with extreme corrosion; specific
geometry; attenuative materials; wide range of plastics.
