A probe for the continuous measurement of the thickness of strips of electrically conducting, magnetic or nonmagnetic strips of material, comprises a the measuring pole (7) arranged in a roller (4) with a narrow running surface. The roller (4) has a ring-shaped crowned middle part (9) in alignment with the measuring pole (7) and is pivoted on a fixed axis of rotation (10) on both sides of the measuring pole (7). The axis of rotation (10) forms part of a housing (12) which screens the measuring pole (7) against external magnetic fields. The roller (4) can consist of a suitable nonmagnetic material, such as nonmagnetic steel, bronze, titanium, ceramic, etc., and the probe can operate according to the magnetic inductive process, according to the eddy current process or according to a combination of these two processes.
