  • >Octave spectrum analysis
  • >Dynamic balancing
  • >Vibration Meter
  • >Order Tracking
  • >Raw data recording




FFT Spectrum Analysis module (optional):
Impaq Elite’s powerful FFT program allows you to conduct cross-channel analysis such as FRF, coherence, and cross power spectrum required for modal, ODS testing or sound intensity measurements.  Also supported is continuous spectral measurements and waterfall display, for proper analysis of varying speed machines.

  • > General vibration analysis
  • > Modal testing
  • > Sound intensity measurement
  • > Operational deflection shape measurement
  • > Bearing diagnosis




Computed Order Tracking module (optional)
The computed order tracking program is designed to analyze the sound or vibration signals of a varying speed machines.  Typical applications for this software module are NVH (Noise, Vibration, Harshness) testing of vehicles or advanced vibration analysis of turbine machines. 

> Order spectrum,
> Order traces,
> Filtered or unfiltered orbits,
> Gap reading
> Centerline of a shaft
> Waterfall plot or intensity map





Octave Spectrum Analysis module (optional)
The octave analysis program utilizes real-time digital filtering technology to generate octave, 1/3 octave or 1/12 octave spectrum.  Conforming to the IEC 61260 & IEC 61672 standards, the octave program is best suited for acoustic or vibration measurements in the field.



Vibration Meter module (optional)

The overall vibration level is a basic parameter for determining a machine’s operational condition.  By simulating the operation of an analog meter, impaq Elite’s vibration meter program performs time domain integration, filtering and root mean square (RMS) calculations for accurate measurements of vibration levels. 




Raw Data Recorder module (optional)
The recorder program directly records raw time data to the built-in compact flash card.  Post processing of Raw Data Recorder files such as FFT, Order Tracking or Octave Analysis from the playback mode can be done with Novian Computer based software.


Rotor Balancing module (optional):

The balancing software module can balance your rotating machines in the field with industry leading balancing techniques like; single plane, dual plane, overhung dual plane, 3 plane, 4 plane and 3 weights balancing. 
Now with multiple-point balancing, vibration in BOTH horizontal and vertical directions are minimized at the same time. 
By enabling coast-down measurements for 1X vibration, the heavy spot is identified correctly with only one measurement, saving you time, money and increasing safety.  T

MODULARIZED APPLICATION SOFTWARE
Because every person may have different testing requirements, Benstone Instruments has developed modular software for specific applications.  It is very easy to install the modular software to an existing Impaq Elite or to download an updated version from our website.  The following application programs are available from Benstone Instruments.
 
FFT Spectrum Analysis module (optional):
Impaq Elite’s powerful FFT program allows you to conduct cross-channel analysis such as FRF, coherence, and cross power spectrum required for modal, ODS testing or sound intensity measurements.  Also supported is continuous spectral measurements and waterfall display, for proper analysis of varying speed machines.
  • General vibration analysis
  • Modal testing
  • Sound intensity measurement
  • Operational deflection shape measurement
  • Bearing diagnosis
 
The standard FFT program supports bearing analysis using Envelope spectrum. Improper enveloping filtering will cause errors and produce improper results.  The FFT program conducts a scanning process by applying different enveloping filters showing the results on a 3D plot for the best envelope filter setting. Apply the bearing frequencies from a built-in bearing database for your complete bearing analysis.


  

 According to ISO 7626-1, the latest version FFT for impaq Elite can show bump test results with Accelerance, Mobility, Compliance and Stiffness functions for investigating the dynamic stiffness of the structure.   Envelope spectrum for detecting bearing failure, bearing damage, bearing fault frequencies: FIT, BSF, BPFO, BPFI   Envelope filter scanning



Computed Order Tracking module (optional)
The computed order tracking program is designed to analyze the sound or vibration signals of a varying speed machines.  Typical applications for this software module are NVH (Noise, Vibration, Harshness) testing of vehicles or advanced vibration analysis of turbine machines.  Calculation of the order spectrum, order traces, filtered or unfiltered orbits, gap reading and centerline of a shaft accurately during a start-up or coast-down process.  The impaq Elite’s order tracking algorithm performs digital re-sampling of the measured signal for ensuring data accuracy.  The order spectrum data can be displayed on a waterfall plot or intensity map. Cut a slice or a trace of data from the waterfall plot and then examine the individual traces.  As shown in the figure below, the user can enter geometric position(s) of the vibration sensors to create a plot to display orbit and shaft centerline motion, which relates to the realistic behavior of a turbine machine.

Octave Spectrum Analysis module (optional)
The octave analysis program utilizes real-time digital filtering technology to generate octave, 1/3 octave or 1/12 octave spectrum.  Conforming to the IEC 61260 & IEC 61672 standards, the octave program is best suited for acoustic or vibration measurements in the field.  For vibration applications, the octave program can perform measurements with user-defined weightings.  One example is that impaq Elite can perform measurements with the special weighting of ISO 6954, ISO8041, ISO2631 and more.  When measuring floor vibration, impaq Elite can display the VC curves on the spectrum, providing real-time evaluation of the vibration severity in the field.

Vibration Meter module (optional)
The overall vibration level is a basic parameter for determining a machine’s operational condition.  By simulating the operation of an analog meter, impaq Elite’s vibration meter program performs time domain integration, filtering and root mean square (RMS) calculations for accurate measurements of vibration levels.  One to Four channels can be measured at the same time, displaying the results to a trend chart, bar chart, or you may record the data continuously to a file.  Easily check vibration severity with the built-in ISO 10816-3 standard.  The user may select different filter settings, or create a user defined filter for special measurements.

Raw Data Recorder module (optional)
The recorder program directly records raw time data to the built-in compact flash card.  For example, a 1 gigabyte file will contain approximately three hours of continuous data with four channels recording at 2 kHz bandwidth.  Post processing of Raw Data Recorder files such as FFT, Order Tracking or Octave Analysis from the playback mode can be done with Novian Computer based software.

Rotor Balancing module (optional):
The Impaq Elite with the (optional) balancing software package can balance your rotating machines in the field with industry leading balancing techniques like; single plane, dual plane, overhung dual plane, 3 plane, 4 plane and 3 weights balancing. This advanced balancing software makes it very simple to balance machines in-field with a very high level of accuracy.  Now with multiple-point balancing, vibration in BOTH horizontal and vertical directions are minimized at the same time.  By enabling coast-down measurements for 1X vibration, the heavy spot is identified correctly with only one measurement, saving you time, money and increasing safety.  This technique prevents the user from danger by putting the trial weights in the wrong place and shortens the time required to balance.
