An ultrasonic thickness gauge is an instrument used to measure the thickness of a material. It is a non destructive testing method that utilizes ultrasonic waves to determine the ultrasonic thickness measurement of the material undergoing investigation. The devices are used to improve safety and to ensure the durability of materials that often face corrosion or erosion. Applications include evaluation of steel thickness in boats and offshore constructions. Pipeline applications are common too.
An ultrasonic thickness gauge measures the time it takes for sound to travel from the transducer through the material. Sound waves bounce off the back end of the component and are measured by the gauge when received. As well as preventing materials from becoming corroded, ultrasonic thickness gauges are also used to test wall thickness and mould thickness in manufacturing industries.
Corrosion gauges with dual element transducers are the primary examination tool used to measure components like:
- Oil and gas pipelines
- Power pressure vessels
- Storage tanks
- Numerous other applications
Precision gauges utilize single element transducers to supply the thinnest range and highest degree of accuracy possible. Common applications include testing the ultrasonic thickness measurement of thin metals and a variety of non-metals like ceramic and glass. NDT stocks both ultrasonic thickness gauges with dual element transducers and single element transducers, contact us for more info.
The advantages of ultrasonic thickness gauges start with the fact that the devices do not need access to both sides of the sample. They can also be engineered to work around coatings and linings. Their accuracy is pinpoint, accurate to a degree of 0.1mm and less, depending on the device. They are also extremely easy to use.
Ultrasonic thickness gauges have been used to determine the presence of fake metals. With knowledge of the speed of sound through metals, owners of Ultrasonic thickness gauge nondestructive testing (NDT) equipment can determine whether an artifact is indeed made of the metal described by the owner.
NDT sells a range of non destructive testing equipment for use in many applications. If you’re in the market for an ultrasonic thickness gauge, we have several available that will fit most industrial, manufacturing and maintenance requirements.
