Benefits and Purposes of Ultrasonic Thickness Gauge

Do you’re employed with massive strong elements in your business, however are you spending an excessive amount of time, power, and cash on thickness testing?

Let’s take into consideration a testing software that may test the thickness of strong supplies, whether or not steel or non-metal.

  • A software that doesn’t break up the fabric.
  • A software that’s straightforward to make use of however moveable.
  • A high-accuracy software that saves money and time.

These are only a few of the advantages you’ll get from utilizing ultrasonic thickness gauges for all your materials thickness testing.

What Is An Ultrasonic Thickness Gauge?


An ultrasonic gauge is a tool used to measure the thickness of a fabric. It really works by utilizing high-frequency sound waves to measure the thickness. It does this by putting a probe known as an ultrasonic transducer on the fabric it’s being examined on. The transducer emits sound waves that go by way of the fabric.

The sound waves journey to the tip of the probe and bounce off the tip of the tube. The time that passes by way of the tube is then transformed into the fabric thickness and proven on the instrument show. Fairly easy, proper?

Historical past of Ultrasonic Gauging

Within the Thirties, the primary makes an attempt have been made to check strong supplies for flaws. The primary business utility of ultrasonic testing was launched on the finish of the Nineteen Forties. Tools producers improved these gauges within the Nineteen Seventies.

These gauges turned smaller, extra correct, and extra versatile to satisfy quite a lot of measurement necessities. As microprocessor expertise developed, so did the extent of efficiency, as demonstrated by the most recent options accessible out there immediately.

How does Ultrasonic Measurement Work?

The ultrasonic wall thickness gauge is made up of a fixture containing a number of ultrasonic sensors across the tube. An ultrasonic sensor is an digital gadget that transmits power from one type of power to a different.

The ultrasonic gauge transmits {an electrical} drive pulse to the ultrasonic sensors and the sensors convert {that electrical} power into ultrasonic sound waves. The ultrasonic sound waves are then mirrored again into the ultrasonic sensors from the wall of the product (e.g. plastic pipe or tube). The ultrasonic sensors convert the power again into {an electrical} waveform.

Relying on the extent of protection required and the extent of accuracy required, the ultrasonic gauge system can use a number of sensors. Every sensor produces an ultrasonic sign which can be utilized to measure one layer or a number of layers of the product.

For multi-layer plastic pipes or tubes, the echo happens at each layer of the product and every layer of the product could be measured individually.

Purposes of Ultrasonic Thickness Gauge


Ultrasonic thickness gauge is especially utilized in materials thickness testing and high quality testing within the manufacturing business. Along with materials thickness testing, an ultrasonic thickness gauge can be used to detect defects that aren’t seen to the human eye. Examples of functions embrace:

Wall thickness Willpower

Ultrasonic wall thickness gauge measures the wall thickness or thickness of supplies. Wall thickness measurement is necessary in industries the place the supplies are uncovered to excessive temperatures and pressures. For instance, within the oil business, excessive wall thickness necessities are essential to stop accidents and losses brought on by explosions or leaks.

Corrosion Checking

What’s corrosion? Merely put, corrosion is the method of rusting steel surfaces. Common ultrasonic thickness gauges are used to check for corrosion regularly. This helps to make sure that constructions meet the required tolerances and reduces the danger of security hazards. Monitoring for corrosion additionally reduces the frequency of frequent repairs, saving you money and time.

Materials Defect Testing

One of many key variations between an ultrasound thickness gauge and different thickness testing units is that ultrasonic thickness gauges can detect defects in strong supplies.

However how does that occur? You could be asking your self, “How is that this attainable?” Properly, let’s break it down for you. Ultrasonic waves journey inside a strong in a predictable sample. Nonetheless, if the sample is disturbed, it signifies a structural flaw and will probably be seen on the instrument show.

Benefits Ultrasonic Testing Gauges

The advantages of ultrasonic thickness gauge in comparison with different materials thickness testing instruments are:

  • Measurement can solely be completed from a single aspect of the pattern materials
  • Supplies exact measurements with values of 0.1 mm or much less Transportable & user-friendly
  • A number of measurements could be carried out in a brief time frame
  • A number of settings can be utilized to handle testing for numerous steel coatings & linings
  • Have a broad measurement vary

What Are the Newest Advances?

Ultrasonic wall thickness gauge options provide high-performance operation and productivity-enhancing options. For example, NDC’s ultrasonic gauge (BETA LaserMike) UltraScan Professional can measure a broad product vary to satisfy the vast majority of wall thickness measurement necessities.

The gauge is provided with “Snap Know-how” for automated ultrasonic waveform setup. Which means waveform setup is instantaneous and totally computerized. Ultrasonic gauge UltraScan Professional presents multi-layer measurement capabilities in addition to ultra-thin wall thickness measurement for measuring as many as 4 layers and as much as the smallest attainable wall thickness.

There may be additionally a high-speed tolerance checking function that can be utilized to test for short-term modifications within the wall thickness of every particular person layer. (The extremely scan professional system could make as much as 10,000 partitions per second, which is ultrafast.) Moreover wall thickness measurement, this gauge additionally has the choice to measure ovality in addition to outer diameter for small to large-size merchandise.

Getting Prepared for Business 4.0

Gauging immediately is about communication and connectivity. And these are the capabilities that immediately’s producers want to contemplate when selecting the suitable ultrasonic wall thickness measuring system for his or her manufacturing operations.

With regards to Business 4.0 help, ensure your ultrasonic gauge system supplies full communications and helps vast Ethernet connectivity comparable to Modbus TCP, profinet IO, profibus DP, Ethernet/IP, and gadget web. These capabilities present the idea for higher operational management and improved processing capabilities for extra environment friendly manufacturing efficiency.
