Deelat’s ultrasonic thickness gauges are available to measure the thickness of metal materials such as aluminum. They can also gauge the thickness in pipes which will help in identifying problems such as erosion. Our lightweight units can be easily transported on the work site and include a user-friendly screen that offers clear, concise readings.

How Do Ultrasonic Thickness Gauges Work?

What Is An Ultrasonic Thickness Gauge?

Ultrasonic thickness gauges are digital devices used to measure the thickness of a material by construction professionals. Thickness gauges provide quick, accurate measurement within fractions of a millimeter, and they can be used on virtually any type of common construction material.

How Digital Thickness Gauges Work

Ultrasonic thickness gauges measure thickness by sending sound waves through a target material. Essentially, the device emits a high-frequency sound wave – which is much higher than the waves humans hear – and the gauge measures how long the wave takes to pass through a material and bounce back.

If you were measuring a steel pipe, for example, the thickness gauge would send a wave that travels through the material, and then calculates the thickness based on the time it takes to receive the echo from the back wall of the pipe. Due to this technology, ultrasonic thickness gauges are extremely precise; some models can record accurate measurements within fractions of a millimeter.

Types of Materials You Can Measure with a Thickness Gauge

Commercial thickness gauges can be used to measure all types of materials, including common construction materials like plastic, metals, fiberglass and glass. Fortunately, you don’t need a specialized meter for the type of material you’re measuring. There are all-in-one gauges, like the BENETECH GM100, that are programmed to measure a range of materials.

One common application of ultrasonic gauges is for measuring the thickness of metals. For instance, construction professionals often consult metal thickness charts, which provide given thicknesses for different types of metal. Gauge 14 sheet metal or aluminum, for example, has a specific thickness.

Why is material thickness important? For one, different ultrasonic gauges are optimized for different types of materials. For instance, thin materials, like Gauge 16 sheet metal, require ultrasonic gauges that produce higher frequencies, while thicker materials require ultrasonic gauges that can produce lower frequencies.

Advantages of Ultrasonic Thickness Gauges

Ultrasonic thickness gauges provide several advantages over other precision measurement tools like calipers and micrometers.

1. Ultrasonic gauges provide non-destructive measurement; they only require access to one side of a material to provide an accurate measurement. That means they can fit into more places, and don’t require cutting out material to gain access.

2. Ultrasonic gauges are extremely precise. Depending on the type of gauge you’re using, you can determine the thickness of a material to within fractions of a millimeter up to several hundred millimeters. Clearly, they’re extremely versatile and the latest gauges are all very accurate.

3. Finally, ultrasonic gauges are easier than ever to use. For instance, the BENETECH GM130 provides auto calibration. These devices can be easily programmed to measure different types of materials, so that switch between measurement quickly. And they’re easy to use; operators point and shoot, and a measurement is provided within seconds.
