Abstract
An acceleration transducer defines a rectangular coordinate system with two orthogonal horizontal axes that are both normal to a vertical axis and includes a main body defining tangential side faces arranged tangentially to the vertical axis, and normal side faces arranged normally to the vertical axis. The transducer includes at least a first piezoelectric element secured to one the three tangential side faces, and exactly one seismic mass is secured to the at least one piezoelectric element, which has a high sensitivity for a shear force exerted by the attached seismic mass along a principal tangential axis and a low sensitivity for a shear force exerted by the attached seismic mass along another one of the three axes.
