offers a cost effective condition monitoring solution with the CSI 9420 wireless vibration transmitters from Emerson.
Vibration monitoring offers several benefits in condition based maintenance programs in most industries. However, every industry has difficult monitoring applications, such as machines that can’t be readily accessed for portable monitoring or machines that are too remote.
Online monitoring with permanently wired instrumentation can be prohibitively expensive in many of these applications. However, wireless vibration monitoring with devices such as the CSI 9420 wireless vibration transmitters helps to improve the reliability of difficult-to-monitor plants with rapid and cost effective deployment.
Wireless vibration monitoring solutions are ideal for applications such as pump health monitoring and conveyor pulley bearing monitoring.
Pump health monitoring
When online monitoring is restricted to a small number of highly critical machines, it leads to a situation where a large number of process pumps receive only periodic checking, while remote pumps may receive very little attention. Wireless monitoring solutions such as CSI 9420 wireless vibration transmitters featuring a standard range of 228m line of sight enable convenient monitoring of remote machines.
Emerson’s scalable pump health monitoring solution incorporates multiple sensor types to detect restrictions, cavitation, seal flush fluid level, process leakage, excessive temperature and excessive vibration, with all the information presented on an at-a-glance interface plus alerts for situations requiring attention.
Conveyor pulley bearing monitoring
A single rolling element bearing failure on a conveyor can stop a production, mining or port operation, and also cause fires and other health, safety and environmental issues. Most conveyors have accessible pulley bearings that can be adequately monitored utilising periodic handheld vibration monitoring transmitters.
However, for bearings that cannot be safely accessed for monitoring or where installing cabling is too costly and impractical, the CSI 9420 works as an ideal solution for monitoring vibration and temperature while providing spectral and waveform data for analysis. Installation time and costs are minimal, while WirelessHART provides reliable and secure data transmission with very low power utilisation.
Case Study: Wireless Vibration Monitoring at Western Australian Mining Site
Engineers at a mining operation in Western Australia realised that they had a serious gap in the coverage of their condition monitoring program. A conveyor shuttle was not being monitored due to access issues, with a potential failure likely to cost millions of dollars in downtime.
Since permanent cabling was not an option, the company decided to install 27 CSI 9420 wireless vibration transmitters to monitor vibration and temperature on conveyor bearings. Commissioned by Alstom MSc, the system is providing vital data to both the plant control system and Machinery Health Manager software.
