Abstract:  
In shot peening apparatus, a device is provided for sensing shot peening intensity and the uniformity of shot flow. It is basically comprised of a detector plate mounted on a cantilevered arm; torque created at the arm mounting due to the impact of shot is measured with a transducer. The detector is mounted on a structure adapted to translate the detector through a large shot peening zone. The invention is especially suited for assuring consistency in a process wherin uniform spherical shot is gravity accelerated to impact a workpiece with uniform velocity.
