impaq Plus Portable 4 channel dynamic signal analyzer

Spectrum Analysis

14 Vibration and Noise Measurement Analysis Functions: Modal Testing、Operating Deflection Shape Testing (ODS)、Envelope Spectrum Analysis、3D Waterfall Plot、Intensity、Testing and analysis of varying speeds, load changes, or vibrations dur-ing startup and shutdown or acceleration.

Octave Band Frequency Analysis

Using parallel time-domain digital filtering technology, it can simultaneously display 1/1 octave, 1/3 octave, and 1/12 octave spectra. The audio analysis includes built-in IEC 61260 and IEC 61672 standards, as well as vibration specifications with special weighting according to ISO 6954, ISO 8041, and ISO 2631. It can also be used for measuring floor vibration intensity with VC curves.

Order Tracking Analysis

Accurate measurement and analysis of the rotational speed order spectrum, order variation trends, filtered and unfiltered trajectories (Orbits), air gap variations, and shaft centerline during the start-up and shutdown processes of rotating machinery. Typical applications include NVH (Noise, Vibration, Harshness) testing for vehicles and vibration problem analysis for turbine rotors.

Online Rotor Dynamic Balancing Analysis

On-site Rotor Dynamic Balancing Calibration for Rotating Machinery
