See full text

A method and geophysical acceleration sensor (100) for measuring seismic data and also for protecting the sensor from shock. The sensor includes a housing (102); a flexible beam (104) having a first end fixedly attached to the housing; a piezoelectric layer (108) attached to the flexible beam; a seismic mass (112) attached to the flexible beam; and a first movement limiter (130) connected to the housing and configured to limit a movement of the flexible beam. A distance between a tip of the first movement limiter and the flexible beam is adjustable.
