Phased array ultrasonic testing that meets your needs
As the world leader in NDT, we believe a name is only as meaningful as the results it delivers.
Waygate Technologies delivers comprehensive phased array NDT solutions for every inspection challenge. Our diverse probe range supports both standard and specialized testing needs across industries.
From material assessment and weld integrity to corrosion monitoring and composite analysis, our advanced portfolio includes capabilities for immersion testing, thin plate examination, and bolt inspection. We provide the precise technology you need, backed by our commitment to innovation.
Krautkrämer ultrasonic thickness probes are designed to measure a wide range of materials. These include:
Metals: such as steel, aluminum, copper, and austenitic alloys (commonly used in oil & gas, aerospace, and manufacturing).
Castings and machined components: including both rough and finished surfaces.
Plastics: widely used in industrial and manufacturing applications.
Composites: such as carbon fiber and fiberglass materials.
Glass: for thickness verification in quality control processes.
Coated materials: including painted or coated metals (using dual multi-mode probes that measure through coatings without removal).
High-temperature materials: when using specialized high-temperature probes designed for extreme environments.
Materials with high sound attenuation: using probes optimized for difficult or low-signal materials.
In general, any solid material that allows ultrasonic wave propagation can be measured, as long as the appropriate probe is selected based on factors like thickness range, surface condition, temperature, and required accuracy.
Choosing the right probe for high-temperature applications depends on your operating temperature, material, and inspection requirements. High-temperature (HT) probes are designed to withstand elevated temperatures—ranging from around 200°C for continuous use to up to 540°C for specialized applications.
It’s important to select a probe that matches your material type, thickness range, and whether measurements are intermittent or continuous. You should also ensure compatibility with your instrument, such as the Krautkrämer DMS Go+ or Krautkrämer DM5E.
For best results, refer to the probe specifications or consult an expert to identify the optimal solution for your application.
The accuracy and resolution of Krautkrämer ultrasonic thickness measurements depend on the instrument and probe combination used, but they are designed to deliver highly precise and reliable results across a wide range of applications.
For high-precision applications, instruments such as the Krautkrämer CL Go+ provide micron-level accuracy of up to 0.001 mm (0.0001”), making them suitable for demanding measurements like thin materials and complex geometries.
Krautkrämer systems also ensure consistent accuracy through advanced features such as:
Zero-cross measurement for stable and reliable readings
Automatic gain control for repeatability in corrosion monitoring
Built-in temperature compensation to maintain accuracy in fluctuating temperatures (up to 540°C depending on the system)
Overall, Krautkrämer thickness probes and gauges are engineered to provide precise, repeatable, and application-specific measurement performance, from general corrosion monitoring to micron-level precision inspection.
Krautkrämer ultrasonic thickness probes are designed for both field and laboratory use. They are engineered to deliver reliable performance in demanding on-site environments—such as pipelines, pressure vessels, and industrial facilities—while also providing the precision required for controlled laboratory applications.
In the field, the probes support applications like corrosion monitoring and maintenance inspections, with options available for harsh conditions and elevated temperatures. When used in a lab or quality control setting, they offer high accuracy and repeatability for detailed material analysis and measurement.
Overall, their versatility allows users to seamlessly transition between field inspections and laboratory testing without compromising on performance or reliability.
Krautkrämer ultrasonic probes are designed for easy maintenance and reliable calibration, ensuring accurate measurements in both field and laboratory environments.
Our instruments include features such as an integrated zero block for quick and simple probe zeroing before use. Routine care—such as keeping the probe face clean and checking for wear—helps maintain consistent performance.
For optimal results, always refer to the operating manual for your specific Krautkrämer instrument and probe.
