Technology

 

The unique Magcam sensor contains a patented sensor chip with an integrated two-dimensional array of 16.384 microscopic Hall magnetic field sensors. Each sensor independently measures the local magnetic field, resulting in a quantitative 2D magnetic field map with high spatial resolution, measured at record speed: less than 1 second for a 12.7x12.7mm² map with 0.1mm resolution. The MiniCube magnetic field camera sensor module only measures 24x24x24mm³. The sensor is mounted in an anodized aluminum enclosure or in a scanner. 

Features and benefits:

  • Quantitative digital magnetic field mapping, 128 by 128 array of Hall sensors
  • Single measurement for full magnet analysis
  • High speed measurements (<1 second per image)
  • High spatial resolution
  • Automatic temperature compensation
  • No moving parts
  • 2D camera mode and line scan mode
  • For multipole and uniaxial magnets, rotors and magnet assemblies
  • Advanced data analysis (see MagScope software)
  • Real-time quality control
  • Suitable for automation

 

Complete quantitative characterization of magnets and magnet assemblies:

Magcam offers a platform for advanced inspection of permanent magnets based on its unique and patented magnetic field camera technology, featuring a high-density 2D Hall sensor array integrated on a single semiconductor chip. The sensor chip records high resolution magnetic field maps at high speed.  
These quantitative magnetic field maps contain large amounts of information about the magnet’s quality. The maps are analyzed using the versatile MagScope  software, resulting in a thorough and fast analysis of the magnet. Many quantitative magnet properties are extracted from the measurement data, making the Magcam system ideal for both R&D and production applications. Magcam also offers measurement and analysis services, renting services and custom software development services.
