| description | The invention discloses an electromagnetic ultrasonic double-wave transducer for bolt axial force detection. The electromagnetic ultrasonic double-wave transducer comprises a shell, a magnet, a clamping ring and a hollow coil, wherein the magnet, the clamping ring and the hollow coil are arranged in the shell; the clamping ring sleeves the outer surface of the magnet part, and the inner diameter of the clamping ring is equal to the outer diameter of the magnet; the hollow coil is arranged below the magnet and is coaxial with the magnet, and the outer diameter of the hollow coil is smaller than that of the clamping ring; the outer side face of the shell is provided with a plug-in port communicated with the interior of the shell, and the plug-in port is electrically connected with the hollow coil. The influence of a clamping structure at the bottom of the magnet on the outer diameter of the hollow coil in the prior art can be solved, and the sensing performance of the electromagnetic ultrasonic double-wave tran |
