STASI (SEISMIC ACCELEROMETERS CALIBRATION SYSTEM)

This paper present a new instrument named STASI (Seismic and Accelerometers Calibration System) invented and patented by Aldo Renato Terrusi of ENEA - Italian Agency for New Technologies, Energy and Environment (patent n degrees RM2004A000147,3-22-2004). This paper is a brief overview on the state of the art at international level, describing and comparing the general characteristics and costs of the instruments in relation with what is currently available on the world market. The modifications on the STASI prototype were made after the I.N.RI.M.'s comments and the experimental tests performed by ENEA Casaccia Metrology Laboratories (SIT Center n degrees 10), which showed an improvement to reliability, calibration's uncertainty of and the ease of use.
