Machinery Health™ Management Product Data Sheet CSI 9420 Wireless Vibration Transmitter n Accurately monitors vibration and temperature in hard-to-reach locations Provides complete vibration data including overall levels, energy bands, high resolution spectra, and waveforms Includes Emerson’s patented PeakVue™ technology for bearing and gear diagnostics Certified intrinsically safe for use in hazardous areas Delivers data and device alerts securely and reliably via IEC 62591 (WirelessHART®) networks Easily integrates into any host via Modbus or OPC with detailed diagnostics via AMS Suite software The CSI 9420 delivers complete vibration information, including high resolution spectra and waveform, over a self-organizing wireless network for use by operations and maintenance personnel. The rugged CSI 9420 Wireless Vibration Transmitter is the first device to provide full vibration data over a self-organizing wireless network. It provides rich information about machinery health for both operations and maintenance personnel. Overall vibration, PeakVue, and temperature readings can be easily integrated into any control system or plant historian while diagnostic data can be displayed by AMS Suite: Intelligent Device Manager or any EDDL compliant host. For advanced diagnostics, high resolution data can be delivered to AMS Suite: Machinery Health Manager for trending and analysis. Cost-Effective, Reliable Monitoring The CSI 9420 extends vibration monitoring to an entire array of new applications. While appropriate for most vibration monitoring tasks, it is especially well suited for hard-to-reach locations, such as cooling towers, pumping stations, remote equipment, and hazardous areas. In general, the CSI 9420 provides an excellent solution for any application that might otherwise involve extensive engineering, cabling, or installation costs. Advanced electronics deliver a high level of accuracy, while the IEC-approved WirelessHART standard delivers exceptional reliability.

Machinery Health™ Management Overall Condition in the Control Room Diagnostic Data to the Maintenance Office The CSI 9420 delivers information about the overall health of rotating assets directly to the control room via Modbus or OPC. Overall vibration data is a good indicator of shaft problems such as imbalance, misalignment, or mechanical looseness. In contrast, the PeakVue reading provides a reliable measure of impacting on the machine. As the PeakVue level increases, it provides direct indication of a developing problem, such as improper lubrication, bearing fault, or gear defect....

Machinery Health™ Management Flexible Configuration Options Wireless Architecture Overview The Power to Get Things Done Ultimate Simplicity There are two power options for the CSI 9420. For a truly wireless experience, utilize the SmartPower™ Module. Based on the low power output defined by the WirelessHART standard, the CSI 9420 can achieve an operating life of up to 10 years when using the Power Save option (update rate set to 2 hours). An operating life of 3-4 years can be expected when using the default settings (update rate set to 30 minutes). Built on the IEC 62591 (WirelessHART)...

Machinery Health™ Management Best-in-Class Security Seamless Integration to Host Systems Emerson’s multi-layered approach to wireless network security builds on the IEC 62591 standard to ensure that your data stays protected – no matter what. Authentication and verification make certain that only authorized devices can join the network, while 128-bit encryption shields your information. Channel hopping maintains operation, even in challenging environments. Easily configure and broadcast measurements to Emerson's DeltaV™ and Ovation™ digital automation systems or any Modbus or OPC compliant...

Machinery Health™ Management High Resolution Spectrum Energy Bands The first compression technique is FFT analysis, which transforms the vibration waveform into a frequency spectrum (shown below). This spectrum not only reduces the file size by over 60%, it also presents the frequency information in a more readable format. The smaller data set accelerates responsiveness of the system while reducing power consumption. As a final data compression technique, the CSI 9420 divides the spectrum into three predetermined energy bands (as shown below). It then calculates the vibration energy within...

Machinery Health™ Management December 2012 By trending the values in AMS Machinery Manager and comparing them to appropriate alert levels, it is possible to set up a system of intelligent alerts that not only inform you when the machine condition is deteriorating, but also provide information about the underlying cause of the problem. The figure illustrates how vibration data can be used to detect and diagnose a developing fault. Based on the increase in overall vibration (black line), an alert would flag the machine as having a potential fault – but with no indication at all about the...
