AA222

Feature and Application

Introduction

AA222 is a tri-axial FBA (Force Balance Accelerometer) with +/-10V voltage outputs. Its dynamic range can be better than 150dB and it is suitable for various applications, such as EEW (Earthquake Early Warning), seismic hazard prevention, as well as RSDH (Rapid Structural Health Diagnostic). AA222 is an easy-to-use, reliable, and robust accelerometer, using IP67 waterproof aluminum alloy enclosure to ensure its performance for all environments.
AA222 provides voltage output and can be used with various brands of recorders; combined with triple technology recorders, it is FA330 integrated seismograph. The bottom of the AA222 is equipped with a mounting tenon, and an alloy expansion screw is attached randomly, which is easy to install; the shell is equipped with a level bubble meter and level adjustment screws, whether it is wall-mounted or ground-mounted, it can adjust the balance of the body, and can be installed with the current vibration. The surface is closely attached, and the measurement is indeed accurate.
