Operating Deflection Shape (ODS) analysis

Operating Deflection Shape (ODS) analysis is a highly detailed motion study to determine root cause(s) of complex vibration issues of a machine and as needed, its accompanying foundation, platform, piping, ductwork etc. Interviews with customer and preliminary testing and will determine the size and scope of the ODS model for optimum results.
An ODS scale model of the test subject is created in the ODS software. Hundreds of frequency, amplitude, and phase measurements are recorded to animate the model with true in-service data.
The model is animated at all applicable frequencies around a full 3D view for motion analysis and videos of important findings are recorded to accompany a full written report of findings and recommended solutions.

On-Line AMS 6500 prediction and protection

For some rotating assets, and the processes associated with them, periodic route-based data collection is insufficient to indicate asset health. Online condition monitoring provides the frequency and types of data necessary to stay on top of developing issues during normal operations and to respond quickly to sudden changes during transient conditions. Emerson’s AMS 6500 Machinery Health Monitor is a versatile, scalable system that can be deployed in a variety of configurations to deliver online condition monitoring exactly as needed for the application.
The AMS 6500 Prediction rack mounted multi-channel machinery health monitor and analyzer help troubleshoot your entire machine or group of machines. It offers optional transient analysis for turbo machinery startup, coast down, and production state monitoring. Monitor and record all channels continuously and simultaneously for hours, days, or weeks – unattended.
AMS Suite integration saves time and facilitates multi-technology integration. PeakVue™ technology can be added for early identification of bearing wear in paper machines, rolling mills, complex gearboxes, and rolling element bearing machines. The CSI 6500 Machinery Health Expert has all the capabilities of the CSI 2140 Machinery Health Analyzer. Portable vibration analyzers are the cornerstone of a successful predictive maintenance program. However, some anomalies, like root-cause investigations and machine train evaluations, can surpass the capabilities of even the most sophisticated 4-channel portable data collector. For example, turbo machinery start-ups, coast downs and production state monitoring require multi-channel, simultaneous recording, vibration monitoring, and real-time feedback to capture rapidly changing events across an entire machine train. For balance of plant critical machines, multi-channel monitoring solution with journal bearing, rolling element bearing, and gearbox monitoring technology is necessary for root cause analysis and to determine if the machine will survive to the next outage.

Ultrasonic Inspection

Ultrasonic Testing Services can be used in any industry. Typical applications include:

Leak Detection:

Ultrasound leak detection covers a wide range of leaks: pressure or vacuum and any gas.

One of the more popular applications for ultrasound is compressed air leak surveys. Technicians are able to analyze and report on cost reduction due to wasted energy.

A major advantage to ultrasound leak inspection is that as a high frequency, short wave signal, ultrasound emissions tend to be localized around the leak site. By scanning an area with an ultrasound instrument, a Technician will follow the sound of the leak to the loudest point. Once identified, the leak amplitude can be noted and recorded for reporting a cost analysis and environmental impact.

How Ultrasonic Leak Detection Works.

During a leak, a fluid (liquid or gas) moves from a high pressure to a low pressure. As it passes through the leak site, a turbulent flow is generated. This turbulence has strong ultrasonic components which are heard through headphones and seen as intensity increments or decibels on the instrument’s display panel. It can be generally noted that the larger the leak, the greater the ultrasound level.

Mechanical Inspection:

Ultrasonic inspection of mechanical equipment has many advantages. It provides early warning of bearing failure, detects lack of lubrication, prevents over lubrication and can be used on all bearing speeds (high, medium and low). In addition, since ultrasound is a high frequency, short wave signal, it is possible to filter out stray, confusing background noises and focus on the specific test point.

Ultrasonic Mechanical Inspection can be used to monitor bearing faults (all speeds), lack of lubrication, prevent over lubrication, compressors, pumps (cavitation), motors, gears/gear boxes, hydraulic systems, fans, couplings, and many others.

Ultrasonic condition analysis is straightforward. The technician can observe sound levels while simultaneously listening to the sound quality, perform data logging, data analysis, trending, trend reports, and spectral analysis through specialized software.

How Ultrasound Bearing and Mechanical Inspection Works

Mechanical movements produce a wide spectrum of sound. One of the major contributors to excessive stress in machinery is friction. Ultrasound instruments detect friction. By focusing on a narrow band of high frequencies, the instrument detects subtle changes in amplitude and sound quality produced by operating equipment. It then heterodynes these normally undetectable sounds down into the audible range where they are heard through headphones and observed on a display panel for trending, comparison, and analysis.


Mechanical Thermography

In the world of mechanical systems heat will most of the time point to impending trouble caused by excessive electrical resistance, lubrication failure, worn components, and other common problems.  These problems can lead to expensive or even catastrophic failures and trying locate the underlying problem can be time-consuming, and manual inspection can be costly.   Because thermography is non-contact and nondestructive the need for a costly shutdown or manual inspection can be eliminated sustaining normal production until a root cause is identified.  This allows us to test production under normal loads and operating conditions in real time ultimately leading to a better understanding of how our machinery if functioning.  In only a matter of hours thousands of points can be collected, inspected, and cataloged allowing a case history to be built for each component of concern. 

Electrical Thermography

Electrical system failures are frequently preceded by a considerable period of increased heat in the faulty components of the system. If the increase in the component heat is detected in time, repairs can be performed before a failure occurs. Infrared thermography is the primary tool tool that can identify areas of abnormality.

What faults can be detected?

Infrared thermography can detect several conditions that may undermine the operational efficiency of your systems. These include overloads, loose connections, inductive heating, open circuits, harmonics, unbalanced loads and defective equipment.


With the high speed at which complex industrial processes run, sudden failure may create hazardous conditions. This could include flying debris that may hurt your workers. By detecting electrical problems in good time, the tool helps to avoid fires caused by overloaded circuits or faulty wiring.

Cost Savings

Inspections using infrared thermography will help in detecting problems and allow for repairs. This will mean fewer downtimes and interruptions in production which will lead to increased productivity, and significant financial savings.


Product quality is dependent on a processes that runs reliably and consistently. When you can deal with electrical problems before failure occurs your systems can operate optimally. This will greatly simplify your delivery quality products.

Lower insurance premiums

With reduced losses and improved your cash flow you will pay lower premiums for commercial insurance coverage that protects against interruptions.

Infrared thermography allows you to perform inspections without interruptions to your process during the inspection as the inspection can be done while systems are running. This will also help to improve your profits.


Field balancing is a technique used to balance a rotating part in place without removing the part from the machine. The advantages of field balancing are apparent, in that time can be saved by not removing the rotating part from the machine and sending it to a shop for balancing.

Imbalance occurs when a shaft’s center of mass does not rotate at the center of rotation.  This results in a heavy spot on the rotor. This heavy spot produces a centrifugal force that forces the rotor to rotate off center and causes a high vibration amplitude at 1x the rotor speed in spectral and time waveform vibration data.

Some of the causes of rotor imbalance can be from eccentricity, improper key length, stress relief distortion, thermal distortion, corrosion or uneven wear, deposit buildup, asymmetrical design, assembly errors, and rotor damage.

For more information please watch the below video that further describes what imbalance is and the methods used to correct it.

Process Optimization

Gain the process insight to optimize every point.

Your job is a balancing act. Downtime and off-spec product reduce your throughput, while challenges like energy inefficiencies, regulatory compliance and facility safety eat into your bottom line. At the same time, an aging workforce is retiring and taking its industry experience with it, leaving you with increasingly less-experienced personnel who must tackle new challenges and ever-changing regulations. To stay competitive, you have to address these constantly fluctuating priorities.

To achieve your goals, your facility must consistently produce at optimal throughput levels. Excessive maintenance, unscheduled outages and process variability all impact production throughput. The Rosemount 3051S Series of Instrumentation provides accurate and reliable measurements every time so you can reduce maintenance, outages, process variability, and achieve faster startups. The Rosemount 3051S also helps reduce maintenance and anticipate problems that might cause an unscheduled shutdown or slowdown by providing added process and equipment insight.

Condition Monitoring:

Condition monitoring is the main tenant to condition-based maintenance, which is performing maintenance after one or more predictive indicators identify that the equipment’s performance is deteriorating or it is going to fail. It is the process of monitoring certain parameters of rotating equipment like vibration and temperature to identify one or more developing faults. In addition, we believe that being comfortable knowing that “all is good” with your equipment is equally important and allows for scheduling production with confidence.

More than just data collection

It sounds simple – routine monitoring of your rotating equipment results in data necessary for deriving information about the condition of your equipment; however, if the data isn’t accurate, your analysis won’t be either. If you can’t acquire data in a timely manner, you will miss early warnings of developing problems. Emerson’s condition monitoring solutions are specific to the application and criticality of your machines, and deliver data you can count on for accurate diagnosis of machinery condition. In any event, Insight to how your equipment is currently operating and how it might be operating in the future allows for scheduling production with confidence or scheduling maintenance to support your production goals.
