  • Beta Gauges
    the thickness of materials or coatings. For nonmetallic materials such as paper, plastic films, or webs, Beta gauges transmit radiation through the material. A radiation or Geiger-Muller detector that is located on the other side of the device measures radiation levels. With coated metallic materials
  • IR, Nuclear and Beta Gauge Instruments
    IR, nuclear and beta gauge instruments use the absorption of radiation to measure the thickness or basis weight of webs, sheet materials or coatings. On nonmetallic materials such as paper or plastic films or webs, the amount of radiation is reflected back or transmitted through the material
  • Thermal Imaging to Gauge Cooling Efficiency in Injection Molding
    and tool design; however this can affect productivity and quality. Thermal imaging is a cost-effective method that can provide valuable information vital to making informed assessments of the issues. Microsoft Word - 2005-028 Shaw.doc. Thermal Imaging to Gauge Cooling Efficiency in. Injection
  • Tension Testing of Metallic Materials (ASTM E8)
    and a nominal thickness of 3/16 inch or more. Sheet rectangular specimens have a reduced area section of 1/2 inch and their thickness should not exceed 3/4 inch. Subsize specimens with a 1/4-inch width can be used for material thicknesses up to 1/4 inch. When the material has a thickness of a 1/2 inch or more
  • Continuous Improvement of Material Characterization Methodology through Gage Repeatability and Reproducibility Studies
    Reliable metrology data such as layer thickness and composition measured by X-ray diffraction (XRD), sheet resistance measured by Eddy current, and qualitative pHEMT epi parameters measured by photoluminescence (PL) are essential in a large-scale epitaxial wafer manufacturing process. In this paper
  • New Materials - New Reliability Issues

Brass. Gauge length. 50 mm. Width 25 mm. Sample size. Parallel length. 60 mm. Width 25 mm, thickness 1 mm, gauge
  • Introduction to Strain Gages
    Strain Gages (gauges): What is a Strain gage? A Strain gage (sometimes refered to as a Strain Gauge) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. A Strain gage
