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.
