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 movement 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, and 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 vibrations 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.

Turn-key Solution For Rotating Machinery

The Dewesoft Orbit Analyzer is bundled with award-winning DewesoftX data acquisition software and a very flexible DAQ hardware configuration. A simple user interface allows quick configuration, measurement, recording, interpretation of the measured results, and building of a printable report. DewesoftX software offers lifetime free software updates and free technical support which ensures a future-proof solution - and cost-free.

DewesoftX also offers other features useful for rotating machinery analysis such as:

  • Order tracking analysis

  • FFT analysis

  • Torsional and rotational vibration

  • Octave band analysis

All the measurements can be performed and analysis performed with the same DAQ device and software. This makes Dewesoft the only provider of such a comprehensive solution bundle on the market. 

With fully-fledged and complete turbomachinery analysis, easy setup, intuitive presentation of measured data, and industry-leading measurement technology orbit analysis measurement is reinvented the Dewesoft way.

The Dewesoft Orbit Analyser solution can be used for research and development or for operational machine condition monitoring purposes. 

Proven and Accurate Measurement Results

Our orbit analysis measurement results have been proven several times by our customers. The measurement and analysis results have been compared to the industry-leading solutions such as Bently Nevada 3500 and Bently Nevada Adre systems, as well as the OROS Orbitgate system. 

The comparison results have proven that our measurements are at least as accurate as the industry benchmark systems.

  • Compressors

  • Drills

  • Generators

  • Turbines

  • Engines

  • Pumps

  • Blowers

Standard visual displays such as recorders, digital/analog meters, etc. are also included with the software by default.

Additional inputs like temperature, CAN bus, deformations, vibration, etc. can easily be added and shown on the same screens.

Simple Machine and Bearings Setup

Dewesoft orbit analysis module offers a simple machine and bearing configuration. Machine configuration setup can be further broken down into subsections.

Machine Configuration

  1. Quick settings: Pair/Mono, CW/CWW, input ch., Angle, Position

  2. Measure: measure the DC gap button

  3. Setup: opens additional settings for the bearing, further explained below under Bearing setup

​​​​​​​Bearing Configuration

  1. Sensors: configure proximity probes, key phasor/tacho position, and angle.

  2. Runout compensation and reference orbit: input runout compensation or reference orbit data into the designated table or simply paste it from elsewhere.

  3. Measurement: set shaft rotation direction, clearance circle size, and shape, number of periods, and averages taken into the average orbit calculation or manually input DC Gap.

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.
