Thickness gauge QuintSonic T Ultrasonic 8-Layer, ElektroPhysik

QuintSonic T ultrasonic coating thickness gauge is an upgraded version of the QuintSonic, proven effective by combining the measurement system with evaluation software in a sensor directly connected to an industrial tablet.

The QuintSonic T measures the individual thickness of up to 8 layers on various substrate materials (e.g., metal, plastic, GFRP, CRFP, WPC, fiber-reinforced composite materials) using the real-time ultrasonic sampling method. All layers are measured in a single operation.

Product Information for QuintSonic T: All measurement parameters are displayed on the screen of the QuintSonic T, which is capable of measuring up to eight layers in a single operation. The device can measure polymer coatings such as paint, gloss, and composite materials, as well as glass, ceramic, or metal coatings on nearly any substrate material. With high accuracy and ease of use, the QuintSonic T can measure all typical coating systems such as:

• Gloss coatings on composite materials
• Composite materials on wood
• Glass coatings on metal, and many other coatings.

With a large 8-inch display, the QuintSonic provides a user-friendly view of measurement results as well as the corresponding ultrasonic signal process (A-scan). Signal adjustment parameters are displayed simultaneously, allowing for real-time adjustments for the current measurement, significantly saving time. Final parameter adjustments can also be made via the new storage option for A-scans.

Thickness gauge QuintSonic T Ultrasonic 8-Layer, ElektroPhysik

Operating Principle

QuintSonic T coating thickness gauge operates based on the ultrasonic reflection principle, specifically the real-time ultrasonic sampling method. When an ultrasonic signal is emitted and encounters a coating or the boundary between two material layers, it reflects back.

The device calculates the time taken for the signal to reflect and return, thereby determining the coating thickness.

Application Range

• Non-destructive measurement of coatings such as gloss, composite materials, glass, and enamel on surfaces like wood, composites, glass, metal, and ceramics.
• Measurement of metal coatings on composite materials, ceramics, and wood.
• Measurement of up to 8 layers in a single operation.
• It can also be used to measure wall thickness.

How to Choose the Right Device

• Measuring Range and Accuracy: Based on your specific requirements, choose a device with an appropriate measuring range, resolution, and accuracy. For instance, if you need to measure ultra-thin coatings, select a device with high resolution.
• Number of Layers to Measure: If you need to measure multiple layers at once, opt for a device capable of measuring several layers, such as the QuintSonic T, which can measure up to 8 layers in a single operation.
• Interface and Features: Depending on the work environment and connection requirements, consider interfaces such as Bluetooth, WiFi, and SD-card.

Considerations When Purchasing a Device

• Certification Standards: Ensure that the device meets international standards, such as DIN EN ISO 2808.
• Operating and Storage Temperature: Consider the operating environment and choose a device that can function within the required temperature range.
• Impact Resistance and Harsh Environments: If the device will be used in harsh conditions, select one with toughened glass and high standards of water and dust resistance.
• Support and Warranty: Make sure the device you purchase comes with manufacturer support and a good warranty policy.

With the features and operating principles outlined above, the QuintSonic T stands as a top choice for those requiring accurate and efficient measurement solutions.

What does the DIN EN ISO 2808 standard indicate?

DIN EN ISO 2808: Determining the thickness of coatings

Purpose and Scope

• This standard specifies methods for determining the thickness of coatings (such as paint, lacquer, and other composite materials) on all types of surfaces, including metal surfaces.
• These methods are applicable to thin, medium, and thick coatings.

Measuring Methods

• Several methods are described in this standard. Specifically, Method 10 (used by the QuintSonic T) involves the use of ultrasonic waves.
• Other methods may rely on mechanical tools such as calipers or the reflection of light.

Applications and Limitations

• In some cases, determining the thickness of coatings can help assess the quality of the coating application or estimate the expected lifespan of the coating.
• However, the application scope of each method may be limited by factors such as the thickness of the coating, the properties of the substrate material, and environmental conditions.

Certification and Compliance

• Businesses or organizations that use or provide coating thickness measurement services are often required to comply with this standard to ensure their measurement results are accurate and comparable.
• Many countries and international organizations have adopted and applied this standard as a benchmark in the coating industry.

DIN EN ISO 2808 standard is an important and widely used standard for determining the thickness of coatings on various surfaces and with a variety of coating types.

What are GFRP, CRFP, and WPC materials?

• GFRP (Glass-Fiber Reinforced Polymer): This is a composite material reinforced with glass fibers. It combines glass fibers and polymers to create a material that is strong, lightweight, and resistant to chemicals. GFRP is commonly used in construction, the maritime industry, and other applications that require high strength with low weight.
• CRFP (Carbon-Fiber Reinforced Polymer): Similar to GFRP, but reinforced with carbon fibers instead of glass fibers. The carbon fibers provide higher strength and rigidity, making CRFP one of the most popular composite materials, especially in aerospace, high-performance automotive industries, and applications requiring high durability.
• WPC (Wood-Plastic Composite): This is a composite material combining wood and plastic. WPC is often used in outdoor applications like decking, fencing, and railings due to its combination of the aesthetic qualities of wood with the durability, water resistance, and termite-repellent properties of plastic.

What is a Histogram Chart?

Histogram Chart is a type of chart that represents the frequency distribution of a dataset. It is used to show the distribution of a continuous variable by dividing it into intervals and counting how many data points fall into each interval.

Here are the key features of a Histogram Chart:

• X-axis: Represents the intervals or bins of data values. These intervals can be of equal width or vary depending on how the data is divided.
• Y-axis: Represents the frequency (count) of data points that fall into each interval.
• Bars: Each bar in the chart represents a specific interval, and the height of the bar represents the frequency of data points in that interval.

Histogram Chart helps to better understand the distribution, central tendencies, variance, skewness, and shape of a dataset. It is commonly used in statistical analysis to identify and visualize the distribution of data.
