Conventional geophone topologies and their intrinsic physical limitations, determined by the mechanical construction, limit their velocity sensing capabilities. Therefore, Magnetic Innovations has developed a novel, patent pending topology with a passive magnetic spring, that overcomes these limitations. The compact, robust and passive design offers new improvement possibilities for semiconductor and seismic industries.
