Benstone Instruments’ Impaq Elite portable, 4-channel real-time analyser

The Benstone Instruments’ Impaq Elite portable, 4-channel real-time analyser is built for advanced noise and vibration measurements. The analyser is designed for operation optimisation, maintenance and design of industrial machinery in mining, power generation, aerospace, marine and ground transportation.

The analyser acquires signals with precision, features 24 bit sigma delta AD converters, and provides a high dynamic range with up to 40 kHz bandwidth. It is equipped with a large 6.4-inch colour touch screen display, which provides a user-friendly intuitive interface.

The analyser’s FFT allows cross-channel analysis such as FRF, coherence and cross power spectrum required for modal test, ODS testing or sound-intensity measurements. Also supported is continuous spectral measurements and waterfall display, required for analysis of varying speed machines. Demodulated spectrum analysis is standard for identifying early-stage bearing faults. Temperature and other parameters are also supported.

Order tracking is used to analyse varying speed machines such as Vehicle NVH testing or vibration analysis of turbine machines, calculating order spectrum, order traces, filtered or unfiltered orbits, gap reading and centreline of a shaft during a start-up or coast-down process. The Benstone Impaq Elite Balancing software can balance the rotating machines using single plane, dual plane, overhung dual plane, three-plane, four-plane and three-weights balancing techniques with a very high level of accuracy.

The Benstone Impaq Elite Octave Spectrum Analysis uses real-time digital filtering to generate octave, 1/3 octave or 1/12 octave spectrum, conforming to the IEC61260 and IEC61672 standards, making it a suitable solution for acoustic applications.
