FIELD: seismic engineering. SUBSTANCE: device has casing with sensitive member located inside. The latter is designed as fiber light guide with inert mass added. The light guide cross- section is reduced and/or its longitudinal axis is bent on some local area of the fiber light guide being the sensitive member of the transducer. EFFECT: improved transducer sensitivity and noise immunity. 2 dwg
