The Ultrasonic Thickness Gauge is used to measure the thickness of material in order to evaluate the properties of a material, component or system without causing any damage to the material using the ultrasonic waves. It is a measuring instrument used for conducting a non-destructive investigation of the material which is one of the advantages of using the device. The test conducted to evaluate the properties of the material such as the thickness of the material for using it in the given application without any fear of damage. The industrial measurement instrument is used widely in various industries that are dealing with plastics, glass ceramics, metal and other materials.

The technique of testing the material is fast, reliable and versatile. It evaluates the thickness of the material as well as the integrity and other physical properties by the means of high frequency sound waves. The technique is used widely for product testing and quality testing. In the thickness gagging application, ultrasonic technique permits quick and reliable measurement of thickness without requiring the access to the both sides of the material.

What Can Be Measured With The Ultrasonic Thickness Gauge?

The ultrasonic thickness gauge can measure the thickness of the materials like plastics, glass, metals, composites, fiberglass, ceramics, epoxies, etc with an ease. The biggest advantage of using the device is; it doesn't require testing both sides of the samples to conclude the results or getting to the conclusion with just one side is fair enough for its accuracy. You can also measure the liquid levels and biological samples with the accurate and reliable results.

The major benefit of using the ultrasonic thickness gauge is it offers non destructive testing of the material which means there will be no requirement of cutting or sectioning of the material. This implies to optimum use of sample without wasting it.

The human ear is able to hear the sound frequencies ranging between 20 Hz to 20 kHz. Ultrasonic is the sound energy which is generated over the broad of frequency spectrum but is relatively higher than the audibility of the human ear. The ultrasonic testing is performed in the frequencies ranging between 500 kHz to 20 MHz, although some special instruments go down to 50 KHz which can be even lower than this or as high as 100 MHz. The frequencies are recorded to declare the final results as to know the working ability of the material. With such deep study of the device, we can estimate the precision of the device and its results.
