ABSTRACT:
A particle detection system for detecting the presence of a particle within a sealed enclosure. It includes a vibrator or shaker whereon is mounted an electromechanical shocking apparatus whereby an operator-actuated switch causes an armature to provide a physical or mechanical shock to the enclosure. A transducer is employed to sense the noise created by a particle within the enclosure striking a side wall thereof, and suitable indicating means are connected in circuit with such transducer to afford visual and audible indications of the presence of the particle. Means is provided for muting the indicators whenever the enclosure is shocked by the armature to prevent the indicators from responding to the noise created by such shocking.
