PROTECTION SIGNALLING APPARATUS Russian patent published in 1995 - IPC

FIELD: protection systems. SUBSTANCE: apparatus provides different responsibility levers of distributed pickups in different channels in dependance upon their mounting conditions. Structure of vibrational pickups allows to enhanced reliability of operation of the apparatus. The apparatus is provided by means, allowing two modes of operation: a mode of noise suppression and a mode of maximally adjustable responsibility. EFFECT: enhanced reliability of the apparatus in conditions of significant vibrational loads of pickups, with a background of vibrational noise and at conditions of distributed surfaces, being protected, with different levels of vibrational disturbances. 1 cl, 10 dwg
