<p>#CMT# #/CMT# For the automatic measurement of the residual field strength in magnetized ferromagnetic workpieces, especially steel pipes (1), a measurement probe (3) is placed at one end (2) of the pipe to measure the emitted residual magnetic field. The probe measures the magnetic field components at the pipe end and also at the outer surface of the pipe for the magnetic fields to be correlated. #CMT#USE : #/CMT# The measurement of the residual magnetic field strength is for fault testing in the quality control of steel pipes. #CMT#ADVANTAGE : #/CMT# The residual field strengths are measured automatically in a rapid, simple and cost-effective process, giving results which can be reproduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the residual magnetic field measurement at a steel pipe. 1 : pipe 2 : end surface 3 : measurement probe 5 : magnetic field at the end side 6 : radial magnetic field components 7 : axial magnetic field components 8 : magnetic field components in the peripheral direction.</p> |
