摘要： The invention relates to a device for non-contact measuring of 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, preferably at a pitch angle of 45 DEG . 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. According to the invention each pick up coil (6-13) encircling the bar (1), which is associated with a strip zone (2, 3), is oriented in relation to the bar (1) in such a manner that the magnetosensitive axis of the pick up coil includes an acute angle, preferably an angle of 45 DEG , with the axis of the bar (1) in the strip zone.
