LATEST PULSE INNOVATIONS EXPAND MEASUREMENT POSSIBILITIES WHILE SAVING TIME AND MONEY. Bruel & Kjaer expands its market-leading PULSE PC-based sound and vibration analyser system with PULSE X, a new measurement solution which delivers innovative and unique technologies for safer, more productive operations, standardised data management, and product problem resolution. PULSE X’s revolutionary Dyn-X 6- and 12-channel input modules boost measurement performance and accuracy over an extreme dynamic input range – for the first time, 160dB. The measurement performance and accuracy of Dyn-X matches or outperforms the capacity of today’s high-quality transducers. Dyn-X technology eliminates the need for an input attenuator for ranging the analysis system input to the output of the transducer. Users no longer need to protect their measurements from overload or under-range situations, but are concerned only with selecting the right transducer for the measurement. Dyn-X is therefore ideal for applications where an accurate measurement has to be right first time, or where many different transducers and unknown signal levels are involved, for example in crash testing, destructive testing, and rotating machinery (run up/coast down). Cutting-edge aerospace and automotive applications will benefit from Dyn-X’s innovative real-time digital signal processing algorithms, combined with state-of-the-art analogue conditioning achieving the utmost quality and accuracy gains. The new technology is also well suited to time-limited applications such as test cells, wind tunnels, road testing, and flight testing, as well as to high-dynamic applications such as structural measurements, impulsive testing, room acoustics and electroacoustics. For field or road testing, Dyn-X requires minimal user interaction, and reduces the skill level required for production line testing. “With the launch of PULSE X, fast and safe measurement results are ensured first time,” says Lars Barkler, Vice President, Technology & Marketing. “Dyn-X enables measurements not previously possible, and improves existing applications. The new technology saves both time and money because trial runs, overloads and the necessity to re-take measurements become things of the past.” A further innovation in Pulse X is an advanced Source Path Contribution (SPC) solution with the emphasis on useability, data management, and Source Path Receiver model management. Bruel & Kjaer provides complete solutions, combining dedicated transducers for measurement of operating and body characteristics with instrumentation and signal processing platforms, contribution analysis, and vehicle target management. Torben G. Nielsen, Business Manager Automotive, adds: “This solution allows NVH automotive engineers not only to comprehend and analyse structural and airborne contributions in vehicles, but also to tune and design sound and vibration contributions according to particular design parameters. A new user interface coupled to PULSE Data Manager provides a framework for a hierarchical vehicle NVH model that reflects the physical structure. An additional benefit of this approach is that targets can be allocated at each point in the model, providing a platform for target cascading and verification.” Finally, users who prefer to record time data and postpone their analysis decisions will appreciate the new, stand-alone Multichannel Data Recorder. This provides an economical replacement for instrumentation tape recorders for in-vehicle or portable recording, from one to hundreds of channels, with a user interface optimised for ease-of-use and productivity. The data recorder can be used directly with PULSE X portable front-ends, and the time files post-processed out in the field or in the office.
