Fieldpaq II portable sound and vibration analyzer
built for advanced noise and vibration measurements in the field.  

> Ruggedized housing, IP 65 rating.  
> 5-inch color (800 x 480 high resolution) touch screen.  
> Powered by  Microsoft's WinCE. 
> Acquires measurement signal with 24 bit sigma delta AD converters
> Up to 40 kHz maximum bandwidth.  
> Powered by a DSP chip for real-time analysis.


 

Connectors on top

> Two BNC connectors on top for dual channel measurements.  
> Use the LEMO 4 pin connector to extend to  4 channels 
> AUX channel provides tachometer signal input and power supply


External memory card and USB interface:

Store your data in the SD card and use USB connection to transferred data to a PC.

 


Optional 2 or 4 channel FFT module

Measures time waveform, Orbit, power spectrum, Cross power spectrum, complex spectrum, FRF, Coherence, PSD and Envelope spectrum


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

Optional balancing module:
The Fieldpaq II’s balancing software package supports simultaneous 4 channel measurements with multiple point balancing technique. 
By conducting coast-down measurements for 1X vibration, the heavy spot can be easily identified with only one measurement saving you time, money and increasing safety.  


Optional Vibration Meter (VM) module
  • Measure overall vibration levels in displacement, velocity and acceleration
  • Measure Crest factor for detecting bearing failure
  • continuous recording over time or RPM

Octave Spectrum Analysis
The octave analysis program utilizes real-time digital filtering technology to generate octave, 1/3 octave or 1/12 octave spectrum.  
Perform measurements with the special weighting of ISO 6954, ISO8041, ISO2631 and more.  
When measuring floor vibration, fieldpaq II can display the VC curves on the spectrum, providing real-time evaluation of the vibration severity in the field.

 

 

Fieldpaq II is a portable 4 channel real-time analyzer that is built for advanced noise and vibration measurements in the field.  For measurements in challenging environments, Fieldpaq II is manufactured with a ruggedized housing by a dual injection molding process and protective sealing to provide an IP65 rating.

FFT Spectrum Analysis (optional):
Fieldpaq II’s 2 or 4 channel FFT program allows you to conduct cross-channel analysis such as FRF, coherence, and cross power spectrum that are required for modal test, ODS testing or sound intensity measurements.  Also supported is continuous spectral measurements and waterfall display, which is required for analysis of varying speed machines.

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

 
 Fieldpaq II’s FFT program also supports bearing vibration analysis as a standard feature.  By taking advantage of demodulation technology, one may see the fault frequencies of a bearing on a demodulated spectrum at its early stage of damage.

Octave Spectrum Analysis (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.

Rotor Balancing:
The Fieldpaq II’s balancing software package supports simultaneous 4 channel measurements with multiple point balancing technique.  Now with multiple-point balancing, vibration in BOTH horizontal and vertical directions is minimized at the same time.  By conducting coast-down measurements for 1X vibration, the heavy spot can be easily identified 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 balance time.  Other features / functions are:

  • > Multi-point balancing
  • > Component calculation
  • > Drill depth calculation
  • > Allowable residual unbalance calculated from the ISO 1940 standard
  • > Unequal radii calculation
  • > Decoupled balancing (couple + static)
  • > Review historical vibration data on a polar plot.
  • > Review historical balancing data on a polar plot
  • > Heavy spot estimation with one shot measurement.
  • > Redo a previous balancing job with saved balancing factors.

Vibration Meter
The overall vibration level is a basic parameter for determining a machine’s operational condition.  By simulating the operation of an analog meter, fieldpaq II'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.
