FAQ:
What is an ultrasonic thickness gauge?
An ultrasonic thickness gauge (ultrasonic wall thickness gauges, ultrasonic thickness tester, ultrasonic thickness meter, UT gauge, etc.) is a precision measuring instrument used to determine the thickness of materials by utilizing high-frequency sound waves. It works by emitting an ultrasonic pulse through a probe (transducer) into the material, then calculating the thickness based on the time it takes for the sound wave to travel through and reflect back. Sound waves reflect from the boundaries between dissimilar materials, and the transducer not only creates the sound pulse, but also listens for the echo.
What's the measuring principle of ultrasonic thickness gauges?
ACS Material ultrasonic thickness gauges feature dual-crystal probe which is consisted of two independent transducers angled, separated by a sound barrier. The instruments use single echo measurement principle. One transducer sends the ultrasonic pulses inside probe which returns after it impacts the back wall and another transducer receives the echo. It calculates the thickness of material by the sound velocity and the time taken between the pulses sent and echo received.
Single-echo UT gauge probes feature a dual element transducer with automatic V-Path compensation. Thickness is determined by measuring the propagation time of the speed of soun , dividing it by two and then multiplying by the velocity of sound for that material.
Why measure wall thickness with ultrasonic thickness gauge and where to use it?
Ultrasonic thickness gauges provide a non-destructive, accurate, and efficient method for measuring wall thickness in various materials. They are particularly useful when only one side of a structure is accessible, making them ideal for inspecting pipelines, tanks, and other industrial components. These gauges help detect corrosion and erosion early, ensuring preventive maintenance and safety. Their versatility allows measurement of both metallic and non-metallic materials, as long as they conduct ultrasonic waves and have relatively parallel surfaces. Additionally, they offer high precision, enabling fast and reliable inspections even in hard-to-reach areas. Industries rely on ultrasonic thickness measurement for quality control and compliance with safety standards, reducing the risk of failures and costly repairs while extending the lifespan of equipment and infrastructure.
The ultrasonic thickness testers are widely used in various industries for non-destructive testing and material quality and condition assessment, including petroleum, chemical, metallurgical, shipbuilding, aviation, aerospace and etc.
