DEVELOPMENT OF TEST RIG FOR CONTROL VALVE FAULT MONITORING SYSTEM USING ACOUSTIC EMISSION

Control valve is an important instrument in process industry. It has been used to control
fluid flow rate in a process control system. The significance of this project is to maintain
the quality of a process besides saving maintenance cost by developing a fault detection
monitoring system using Acoustic Emission (AE) technique. The concept of AE
technique is to attach a sensor at the body of the valve to detect fault and as a monitoring
system. Since faults on control valve often happens in the plant, there is a need to carry
out background study in order to investigate the problems occurring. This leads to the
project objectives that are to design and build test rig for experimentation purposes
followed by further analysis on the collected data. Based on the studies that have been
done, it is believed that the project is feasible and realizable.
