description The invention discloses an electromagnetic ultrasonic sensor for bolt axial force detection, which comprises a shell, and a magnet and a coil which are arranged in the shell, the coil is arranged below the magnet and is coaxial with the magnet, the outer side surface of the shell is provided with an insertion port communicated with the interior of the shell, and the insertion port is electrically connected with the coil; wherein in the direction from the magnet to the coil, the side surface of the shell for accommodating the coil is in an inward shrinkage trend. According to the invention, the influence on the bolt axial force test due to the existence of the steel seal on the surface of the bolt in the prior art is solved. 本发明揭示了一种用于螺栓轴力检测的电磁超声传感器，包括外壳及设置于外壳内的磁体和线圈，线圈设置于磁体下方，且与磁体同轴线设置，外壳外侧面设置有连通外壳内的插接口，插接口与线圈电性连接；其中，沿磁体至线圈方向上，容纳线圈的外壳侧表面呈内缩趋势。本发明解决现有技术中由于螺栓表面钢印的存在而对螺栓轴力测试的影响。
