ABSTRACT:
An accelerometer having a base unit carrying one or more transducers and encapsulated in a housing. The base includes a base piece and a prism-shaped stud with a rectangular cross-section having shear sensitive transducing elements, with associated seismic masses, fixed on the opposite, wide faces of the stud. The stud is shaped like an inverted T, so that the cross-section of the lower T-bar part has the same thickness but a greater lateral dimension than the T-leg part which carries the transducing elements. The stud is affixed perpendicular to the base piece with high precision using the lower T-bar part of the stud as a guide, and is easily fastened to the base piece without the use of screws or cement.
