How to measure steel thickness using an ultrasonic thickness gauge…
Determining the thickness of materials where you only have access to one side, such as tank walls or pipelines for example, is typically achieved through ultrasonic thickness measurement, using an ultrasonic thickness gauge, which is a form of non-destructive testing or NDT Inspection.
The Elcometer MTG2 Ultrasonic Thickness Gauge has been designed to provide fast, accurate material thickness measurements of uncoated steel substrates – ideal for monitoring corrosion and erosion before painting.
This video is a basic introduction to the Elcometer MTG2, and ultrasonic thickness measurement using an ultrasonic NDT gauge.
Using an ultrasonic pulse to determine the thickness of the material, the Elcometer MTG2 ultrasonic material thickness gauge provides instant and reliable steel thickness measurements from just one side of an uncoated steel substrate.
Using a small amount of ultrasonic couplant, you press the dual element transducer flat against the surface.
When the transducer is placed correctly on the material, the reading stability indicator shows how strong the ultrasonic signal is – a full bar means a strong signal; ensuring accurate, reliable
measurements.
With a pre-set measurement rate of 4 readings per second (4Hz), the Elcometer MTG2 can measure uncoated steel up to 500mm (20”) thick, with a maximum accuracy of ±1% across its range.
Pre-calibrated specifically for steel, the Elcometer MTG2 ultrasonic thickness gauge is ready for use straight out of the box to measure steel thickness. Simply zero-point calibrate using the integrated zero disc, to ensure accuracy at all times.
You can connect the Elcometer MTG2 ultrasonic material thickness gauge to a computer using a USB cable, and you can transfer your readings live to ElcoMaster, Elcometer’s free software for PC – along with all of your other inspection data; such as surface profile or surface cleanliness readings, among others – to generate professional inspection reports, instantly.
So you can now measure steel thickness using an ultrasonic thickness gauge, but what if you want to non-destructively measure the thickness of a material that’s already been coated? Or measure materials other than steel, such as aluminium, copper, plastics, porcelain or epoxies for example?
That’s where the Elcometer MTG4, MTG6, and MTG8 Ultrasonic Material Thickness Gauges come in.
