  • 8 Tips to Improve Your High-Temperature Corrosion Thickness Measurements
    Ultrasonic thickness gaging isn't limited to testing materials at normal (ambient) temperatures. Measurements can be made on materials whose surface temperature approaches 900 °F (500 °C). When working with metals, there may be times when the thickness needs to be measured during an ongoing process
  • Theory and Application of Precision Ultrasonic Thickness Gaging
    permit quick and reliable measurement of thickness without requiring access to both sides of a part. Calibrated accuracies as high as ±2 micrometers or ±0.0001 inch are achievable in some applications. Most engineering materials can be measured ultrasonically, including metals, plastic, ceramics
  • Optimised Metal Strip Measurement
    , the thickness profile of the metal strip is an important feature. There are many different approaches for measuring the thickness profile. A very interesting solution is provided by Micro-Epsilon, a sensor and system manufacturer from Ortenburg.
  • Introduction to Eddy Current Testing
    and service environments that require inspection of thin metal for potential safety-related or quality-related problems. In addition to crack detection in metal sheets and tubing, eddy current can be used for certain metal thickness measurements such as identifying corrosion under aircraft skin, to measure
  • High Precision Production Control in the Metal Industry
    Slabs, sheets or strips of steel, aluminum or non-ferrous metals are manufactured with ever tighter manufacturing tolerances. A decisive parameter in the production process is the thickness of the metal. In order to achieve high precision thickness measurements, laser scanners from Micro-Epsilon
  • Applying Infrared Imaging Techniques to Marine Surveying ... continued
    Audio gauging or ultrasonic thickness (UT) measurements are a common non-destructive testing method employed to determine the thickness of the metal and extent of corrosion based on the known original thickness of the metal plate. During the preparation for UT measurements, by chance I pulled out
  • Outer PI Loop Considerations
    , controlling the speed is necessary but not sufficient in controlling the process. When speed control alone does not achieve desired results, then outer Proportional-Integral (PI) loop control can be applied. One example is a metal strip that must be elongated to a set percent as part of the process
  • Application Considerations in Specifying High Frequency Ultrasonic Transducers
    materials like fine grain metals, ceramics, and thin polymers, these higher test frequencies permit measurement of significantly lower thickness limits and detection of significantly smaller flaws and other internal structures as compared to conventional test frequencies of 20 MHz and below. However
  • A Microfluidic System for Biological Particle Enrichment Using Contactless Dielectrophoresis
