SEISMIC DETECTOR Russian patent published in 1995 - IPC

Abstract RU 2046375 C1

FIELD: vibrations parameters measurements. SUBSTANCE: seismic detector has body, mounted in it base with nonmagnetic hollow cylinder, inertial mass in the form of permanent magnet, transversal fixer, acting as transversal magnetic taut ligament ferromagnetic cylinder, ferromagnetic cups, inertial mass vertical movement sensor. Seismic detector own frequency adjustment is exercised by vertical motion of cups in respect to nonmagnetic cylinder. EFFECT: simplification of design. 2 cl, 1 dwg
