GEOPHONE Russian patent published in 1997 - IPC

Abstract RU 2076341 C1

FIELD: seismometry. SUBSTANCE: invention can be used in the capacity of borehole and bottom geophone in sea seismometry. Cylindrical body is completely filled with liquid inertial mass and houses N piezoelements in the form of symmetrical two-side bimorphous cells which planes are perpendicular to end faces of body placed in symmetry relative to major planes of body by its end faces. Piezoelements anchored close to different end faces of body are intercoupled electrically in counterphase. EFFECT: expanded application field, improved functional reliability. 4 cl, 3 dwg
