Input Modules: Dyn-X

Based on state-of-the-art, new technology, and with a useful analysis capacity exceeding 160 dB in one range, Brüel & Kjaer introduces a new, revolutionary set of input modules.

These will not only save you time and work, but will also allow you to make measurements not previously possible. Gone are the days of trial runs, overloads and under range situations. Gone are the days of repeating measurements, and setting input ranges.

This new range of modules covers all signal levels from 0 to 10V in one range - and there are no technical drawbacks. In fact, with these new modules all you have to worry about is choosing the right transducer.

160 dB in One Range

To date, high-quality transducers and preamplifiers have outperformed measuring equipment with regard to linearity and dynamic performance, being able to deliver a noise- and distortionfree signal over a dynamic signal range of 120 to 130 dB broadband and 160 dB narrow-band. Now, with Dyn-X technology, the entrie measurement and analysis chain, from the transducer to the analysis results, for the first time matches or outperforms the transducer used for measurement. This eliminates the need for an input attenuator for ranging the analysis system input to the output of the transducer.

Accuracy, Safety and Efficiency

With no input range to set, you no longer have to worry about overloads, underrange measurements or discussions about the validation and verification of measurement results. And with no need for trial runs to ensure that the input range is correct, you have a far greater certainty of getting measurements right first time. The measurement situations and applications below are examples of where the new Dyn-X technology can be usefully employed:

When you need to get the measurement right first time:

• crash testing 
• destructive testing 
• heavy machinery - run up/coast down

Where there's minimal user interaction:

• road testing 
• field testing

When time is limited:

• test cells
• wind tunnels
• road testing
• flight testing

When testing is unattended:

• production line 
• noise monitoring

When signal levels are unknown:

• run up/down 
• field testing

When an overview of the whole measurement scenario is difficult:

• when measuring many channels 
• when combining more signal types: vibration, sound, temperature, pressure, RPM, etc. 
• test cells
• in-car testing 
• sound, vibration and other parameters involved

High-dynamic applications:

• impulsive testing, room acoustics 
• run up/down 
• electroacoustics 
• structural measurements
