Abstract

This paper presents the application of a Self-exited Acoustical System (SAS) for monitoring stress changes in the cement plant. The change in the speed of wave propagation, which is associated with a change in the resonance frequency in the system is caused by the deformation of the examined material. The SAS system is based on this phenomenon and can be used for the indirect measurement of the stress changes in the material.
