Orbit Analysis
Application Overview

Measuring vibration data on a rotating machine is a strong diagnostic tool enabling the detection and prevention of many types of potential faults and machinery downtime.

Orbit analysis is an ideal analysis tool for rotor movements examination and assessment of any movement restrictions causing vibration. It prevents potential, unwanted damages to rotating machinery that would result in premature wear of components and could cause critical failures. It also helps to determine lubrication state, bearing states and can optimize machine operation.

Dewesoft orbit analysis works independently of a machine type. It can be a power plant or a high revving compressor. Steady, continuous operation with as few malfunctions and vibration as possible is essential for maximizing productivity and ensuring the reliable operation of a machine. To achieve this, measurement and analysis of rotational vibration data are crucial.

Multiple Machine Trains Monitoring

To save time, you can mount multiple sensors and measure and monitor several machine trains within the same setup in parallel. This is very useful when you want to monitor and analyze several machine trains at the same time.

The configuration is as simple as using a single instance. There can be any number of bearings defined within individual machine trains even when using more than a single instance of Orbit Analysis.

Proximity Probes Compatibility

Dewesoft orbit analyzer is compatible with most of the proximity probes on the market. In most cases you can use your existing installed proximity probes.

We suggest using Micro-Epsilon probes. Most of these probes can be connected directly to our data acquisition LV signal conditioning module without the need for a separate power supply. Probes cam bi powered directly from our signal amplifiers.

Can we integrate Bently Nevada proximity probes?

Yes. Depending on the customer’s system we can either connect to conditioned signal (3500) or directly to the proximitor using the power supply on the LV module.

FAQ

What is orbit analysis?

Orbit analysis is a tool for vibration analysis on rotating machinery, especially those machines that are permanently equipped with proximity probes for vibration measurement. The process is essentially an extension of time waveform analysis as it uses time-domain data from a pair of orthogonal probes plotted on an X-Y graph with consideration for the physical location of the proximity probes. 

What is orbit plot?

Orbit Plot displays the movement of the shaft centerline for orbit analysis on sleeve bearings. Orbit Plot requires two or four channels and the turning speed. If you use a tachometer, the signal is recorded automatically.

What is polar plot?

A polar plot is a single display in a polar plane displaying phase and amplitude (displacement) at certain RPMs.

What equipment is needed to perform orbit analysis?

A typical configuration would consist of a pair of proximity probes and a keyphasor (tacho probe) per one bearing. Dewesoft supports a virtually unlimited number of bearings, so this configuration can be multiplied as many times as needed in a particular application. If needed, Dewesoft Orbit Analysis also supports mono configuration with a single probe per bearing and offers additional customizability options to suit different measurement needs.

Do you support any industry typical orbit analysis displays?

Yes. There is a predefined Orbit Analysis screen to help you out in the beginning and there are virtually unlimited options when it comes to defining your measurement screen. In short, we support:

  • raw/direct orbit (with clearance circle)
  • averaged orbit (with clearance circle)
  • filtered/NX orbit
  • Shaft centerline (with clearance circle)
  • Full motion graph
  • Bode plot
  • Order and FFT waterfalls vs. RPM.

Channels are easily added to different dedicated displays (Orbit plot, Polar plot, 2D graph) in order to create exactly what you need. For example, the shaft centerline with a clearance circle is easily transformed into a full-motion graph with a single click.

Is Dewesoft Orbit analysis capable of compensating for shaft shape irregularities?

Of course. This is done through dedicated Runout compensation, which can be performed at any desired rotation speed. The user inputs the speed and selects the number of revolutions to average when performing the runout compensation. The compensation itself is handled through a dedicated measurement screen and is completely automated once started.

Are future updates and upgrades to the Orbit analysis module free?

Absolutely. All DewesoftX data acquisition software upgrades are free for all users and there is no exception to the orbit analysis module. The new future updates will be available for free to all existing users.

Do you offer monitoring capabilities together with Orbit analysis measurements?

We do. Our Historian time-series database can offer a complete solution for long term machine condition monitoring. Since these systems can vary in their architecture and requirements, we recommend getting in touch with the local representative and they will arrange for our engineer to contact you and prepare a solution for your measurement needs.

What proximity probes do we recommend and how do we connect them to our DAQ systems?

We suggest using Micro-Epsilon probes. Most of these probes can be connected directly to our LV module without the need for a separate power supply.

What if the customer already has probes?

We can support most of the probes out there, but to be sure it is better to contact our support team if unsure about supply voltage and ranges for the particular probe.

Can we integrate Bently Nevada proximity probes?

Yes. Depending on the customer’s system we can either connect to conditioned signal (3500) or directly to the proximitor using the power supply on the LV module.
