Enhancing Magnetic Field Measurements in Room Temperature Environments

This study by V. Remondino on March 21, 2006, analyzes the accuracy and limitations of room temperature magnetic measurements. The research explores the relationship between modulation, phase, eccentricity, and more. Results indicate that MQTL production surpasses MQT/MQTS accuracy and is near mechanical limits. Variation in azimuthal and radial shifts, along with coil width, is identified as a key harmonic factor.

  14. Conclusion • MQTL production is more accurate than MQT/MQTS (~ 30 %) and close to mechanical limits (0.1 mm) • The major cause of harmonics is variation in Azimuthal shift (Phi) and radial shift (RSHIFT) and width of coil (DFAK). FQWG
