Every day there are new innovations to make our tasks easier and more efficient in the work place. So why risk the success of your PdM (Predictive Maintenance) program on yesterday’s technology? With the GO EMERSON trade-in program, you can take advantage of the latest technology for data collection, analysis, and communications. Trade in your existing non-Emerson route-based vibration system for the AMS 2140 Machinery Health Analyzer.
Introducing the AMS 2140
With the AMS 2140, Emerson resets the bar for speed and efficiency in both data collection and advanced testing of a broad range of equipment in your plant. With more than 25 years of experience, Emerson’s latest release continues to be best-in-class:
- Simultaneous four-channel data collection moves you quickly through your collection route and makes easy work of advanced testing.
- New Lithium-Ion battery provides the longest battery life available.
- Collect all three bearing data collection orientations simultaneously using one of the fastest four-channel analyzer available on the market.
- Thinnest unit, lightweight, and comfortable for single hand operation.
- Wireless and Bluetooth capabilities enable communications from the field to the office, or from the analyzer to accessories.
Traditionally, control rooms did not receive vibration data due to the need for specialized training and tools to extract valuable information from the data.
Emerson's innovative PeakVue technology simplifies machinery analysis, offering a straightforward and dependable indication of equipment health through a single trend.
By filtering out conventional vibration signals, PeakVue focuses on impacting, which serves as a superior indicator of overall asset health for all types of rolling element bearing machines.
And now, with the introduction of PeakVue Plus, users will find it even easier to take advantage of this technology.

Let’s look at a typical process pump running between 900 and 4,000 RPM as it passes through the four stages of bearing failure. Starting with the baseline condition for a good bearing, we see a significant amount of overall vibration. However, it is important to note that the PeakVue value is at zero. This is because a good machine, properly installed and well lubricated, should not be impacting. Therefore we can state the Zero Principle – PeakVue on a good machine should be at or close to zero.
At stage 1 bearing failure, initially the defect is not visible to the human eye. There is no change in the overall vibration, but PeakVue already provides an indication that something is happening. When it climbs to a value of 10, there is a problem on the bearing.
At stage 2, small pits will being to appear, and the bearing will have less than 10% of its service life remaining. Typically there is still not indication of the developing faults in the overall vibration, but PeakVue continues to climb. When it doubles to 20, there is a serious problem with the bearing.
At stage 3, the bearing damage is now clearly visible. You may start to see a small increase in overall vibration of +/- 10%. Meanwhile, PeakVue continues to show the progression in fault severity.
In the final stage of bearing failure, the overall vibration might rise 20% or more. In comparison, PeakVue continues to increase sharply – perhaps as high as 40 g’s – and signals that the bearing is approaching end of life.
There will be a marked incrase in the overall vibration at the point of actual failure, but too late for planning. This in in effect notification that the machine is shutting down. In contrast, PeakVue has been indicating a developing fault over the past weeks and months. Immediately prior to failure, PeakVue levels may surge rapidly to 50 g’s or higher.
