  • Low-Field Magnetic Sensing with GMR Sensors
    Industry continues to reap the benefits of. solid state magnetic field sensing. Every day new. applications are found for solid state magnetic field. sensors due to their small size, low power. And. relatively low cost. The new frontier for these solid. state sensors is very low magnetic fields
  • Ten Easy Things to Do with Magnetic Sensors
    The measurement of magnetic fields for their own sake is a relatively uncommon goal outside the laboratory. It is more typical (in industrial, consumer, and automotive applications, for example) to see a magnetic field used as an indicator of some other phenomenon such as position or speed. Over
  • Imaging Dilemmas in 180 Hz Magnetic Fields
    While performing an IR scan of substation cable spaces, a thermographer detected an anomaly in the imager display. The problem was most obvious when the imager was near the neutral inductors and cables in the substation. While the thermal imager is exposed to a variety of magnetic fields within
  • Chemists Spin Materials To Improve Magnetic Resonance Data
    COLUMBUS, Ohio -- An Ohio State University chemist and his colleagues are taking new, high-tech materials for a spin -- inside a nuclear magnetic resonance (NMR) instrument. Philip Grandinetti, associate professor of , and his research partners have named their new technique FASTER, short
  • Measurement Techniques for Incremental Sensors: Encoders, Frequency Counters, Magnetic RPM sensors, etc.
    Measurement of angle, distance, frequency, and speed, as well as general event counting measurements are commonplace in a variety of industrial situations including gearboxes, engine and motor operation, conveyor belts, milling and drilling machinery, and robotic assembly systems. This paper
  • Electromagnetic Field Measurements in the Near Field
    Electromagnetic Field Measurements in the Near Field. This text examines measuring methods for EMF, electric and magnetic fields, power density, and photonic EMF. The author describes methods that provide accurate data to aid in development of new, improved standards for labor safety and public
  • Current Transformers Provide Accurate, Isolated Measurements (.pdf)
    advantageous to determine the current flowing in a conductor by means of its associated magnetic field. This provides isolation between the measuring equipment and the circuit being measured.
  • Coating Thickness Measurement: The Fundamentals
    the surface and the base substrate is measured. Inside the measurement probe is a coil that generates a changing magnetic field. When the probe is placed on the substrate, the magnetic flux density of this field is altered.
