HORIZONTALLY OMNIDIRECTIONAL ELECTROMAGNETIC SENSOR

An omnidirectional sensor which converts planar movement of a seismic mass into an electrical impulse by electromagnetic induction. The seismic mass is a hollow cylinder having the lower edge thereof slidable on a horizontal planar apertured surface of a support. A stop member extends through the ma...

Zusammenfassung:	An omnidirectional sensor which converts planar movement of a seismic mass into an electrical impulse by electromagnetic induction. The seismic mass is a hollow cylinder having the lower edge thereof slidable on a horizontal planar apertured surface of a support. A stop member extends through the mass and aperture and limits movement of the mass along the surface under an acceleration pulse of predetermined amplitude and time.
