Abstract :
A standard measuring system (setup) has been developed at VNIIM to be used for the calibration of magnetic flux density gradient (MFDG) coils, sensors and magnetic gradiometers (MG). This measurement standard is based on the calculable quartz coil used for the reproduction of gradient which is uniform in a specified working space. It also includes measuring equipment to compare coils, gradiometers and differential measuring transducers. Theoretical and experimental aspects of the problem are discussed. The developed standard system allows calibrating MFDG coils with an uncertainty of 0.1 % within the range from 0.005 to 0.5 T/m.
