Abstract: The invention relates to a device for non-contact measuring of stresses including bending stresses in a bar-shaped body (1), e.g. a cylindrical bar, shaft or the like. In at least one transverse zone (2, 3) the bar (1) is provided with a number of thin strips (4) of an amorphous magnetoelastic material, distributed along the circumference of the zone, said strips (4) being affixed to the circumferential surface of the zone and extending at a pitch angle therealong, a preferably at a pitch angle of 45.degree.. Means (5) are provided for generating a magnetic field over said zone (2, 3) and a pick up coil (6-13) encircling the bar is provided for each zone (2, 3), said pick up coil being connected to a measuring unit (16, 16A) for indicating signals generated in the coil.
