Question posted - March 16 to March 20, 2015:

How do you calibrate a DFT gauge in the magnetic field of a live power plant to measure coatings on steel substrates?

Selected Answers

From Tolga DIRAZ of CARBOLINE Turkey - Bursa Plant on March 19, 2015:
I suggest that the Faraday Cage Law may be utilized to construct a shielding enclosure around the DFT gauge, to prevent  interference from the electric and magnetic fields of the live power plant. Any comments?

From Antonio Leal of IMMT-Institut Macaé Tecnology and Metrology on March 4, 2015:
This issue should be analyzed by a specialized physicist in this area, and testing should be performed. It is logical that the magnetic field will interfere with the measurement result since  the measuring principle works that way. Also, the tool uses the parameter of  atmospheric pressure, working in a place with hyperbaric pressure. Metrology and the science in general  are not resolved.
