Abstract

PURPOSE:To avoid inconveniency caused by erroneous sensing due to the directivity of amplitude by a method wherein vibration is grasped as the swinging width of a sphere within a spherical body. CONSTITUTION:A sphere 1 is a vibration sensitive body in the form of a true sphere with a steel sphere as the basic sample, while 2 refers to a sensory container equipped with the sensory body 1. The sensory container can be freely installed, matching a sensory mechanism constructed for raw material, its size, mutual diameter rates, etc. The sensory container 2 is designed to make the occurrence of contact sound natural, while the inside surface for operation is reduced to a certain R one to secure the unforced operation of the vibration sensitive body 1 and select the suitable material and wall thickness from time to time. A microphone 3 is mounted on the lowest bottom of the circumferential surface of the container 2, so that the microphone is used to catch the contact sound of the sensory body 1 and the container.
