What Is An Ultrasonic Thickness Tester?
An ultrasonic thickness tester is a sophisticated tool often used in industrial environments. This article focuses attention on ultrasonic thickness testers, what they are, their advantages and disadvantages and provides common examples of their use.
What is an Ultrasonic Thickness Tester?
An ultrasonic thickness tester, also known as a thickness gauge, employs a non-destructive method to determine the thickness of a component or material.
How do Ultrasonic Thickness Testers Work?
Ultrasonic thickness testers determine sample thickness by measuring the amount of time it takes for sound to cross from the sensors transducer through the measured material and back to the transducer. The ultrasonic thickness tester will then rapidly and automatically calculate the data based on the speed of the sound through the tested sample and display the resulting measurement on an LCD.
There are several advantages and disadvantages of ultrasonic thickness testers.

Advantages |
Disadvantages |
+Â Â Â Â Â Â Â Non-destructive measurements. +Â Â Â Â Â Â Â Access to both sides of the sample is not required. +Â Â Â Â Â Â Â The sensors can be engineered or calibrated to measure and cope with coatings and linings. Â |
-Â Â Â Â Â Â Â Â Â Usually requires calibration to specific materials. -Â Â Â Â Â Â Â Â Â The sensors require good contact with the surface area to be measured. -Â Â Â Â Â Â Â Â Â Coupling material between the measured surface and the probe is often required. |

Applications for Ultrasonic Thickness Testers
Ultrasonic thickness testers are used to check material thickness and properties regularly throughout many industry applications. Common examples include the measurement of:
- Metal thickness
- Corrosion monitoring
- Wall thickness
- Casting/moulding thickness testing
- Paint and coating thickness; and
- Plastic thickness.
