Acoustic Automatic Test System

 

System Introduction

Mainly consisting of automatic test systems for acoustic launching/receiving, the Acoustic Automatic Test System performs static acoustic measurement on acoustic devices. The measurement items include: Level of launch sound source, launch directivity, axial sound pressure of launch, frequency response of launch voltage, frequency response of launch current; level of receiving susceptibility, response level of receiving susceptibility and receiving directivity under certain frequency; energy transducer impedance characteristic measurement, etc. The automatic control system of traveling crane uses energy transducer of PLC for system test to position automatically in directions of X, Y, Z and θ, and revolves synchronously with the measurement system during directivity measurement.
