INTRODUCTION MICROPHONES COUPLERS

BRÜEL & KJÆR TRANSDUCERS Transducers have been a core part of Brüel & Kjær’s business for more than 70 years. The quality of our transducers is world‐ renowned and is the result of our unique experience and knowledge, backed up by meticulous testing and quality control, which ensures that you get the performance and durability you expect. But Brüel & Kjær goes beyond transducers. We are unique in the industry, producing all of the elements for complete sound and vibration test systems. Our goal is to create the most technologically advanced solutions, built to the highest quality and...

Our Development and Production Process Development from the Beginning We determine the specification of a new transducer based on input from our customers, their requirements, and our own product development plans. Using modern simulation and analytical tools, such as finite element models (FEM), we can, early in the process, begin to optimize the performance of the new design and reduce development time so the first units reach customers faster. Every Brüel & Kjær transducer is thoroughly tested during its production to ensure that its performance is within the specified parameters. Extremely high standards are met in our production...

Our Implementation of TEDS A wide range of TEDS (transducer electronic data sheet) transducers are available from Brüel & Kjær. TEDS is standardized by the Institute of Electrical and Electronics Engineers (IEEE) and is supported by many front ends and conditioning amplifiers including Brüel & Kjær’s PULSE LAN‐XI data acquisition, VC‐LAN vibration controllers, 16‐channel Conditioning Amplifier Type 2694, the NEXUS line of conditioning amplifiers, and many more. TEDS offers a number of benefits: • Plug and play facilities • Type, S/N, sensitivity and more read directly ...

TEDS Templates The TEDS template defines the memory mapping of the TEDS chip and hence the “understanding” between transducer and front end. A number of TEDS templates have been standardized by the IEEE and in addition to this, a number of non‐standard vendor specific templates exist. The different TEDS templates are differentiated by different ID numbers. See TEDS Microphones for a listing of the templates used with Brüel & Kjær microphones and preamplifiers. Ordering Transducers To order from Brüel & Kjær, you just need to know an item’s order number. For transducers and signal conditioners, these will be a...

Brüel & Kjær launches the world’s first high‐stability, measurement grade, electret microphones Falcon series is introduced. Featuring stainless steel, press‐fitted diaphragms, these microphones result in a step change in microphone technology The world’s only one‐unit Sound Intensity Calibrator enables calibration without dismantling the probe Surface Microphone – a Brüel&Kjær first: an “all titanium” sensor originally developed for aerospace applications Surface Microphones now also find their way into the automotive industry, where they break new frontiers in wind‐tunnel testing World’s first outdoor microphone where all parts exposed to the weather are ...

World’s first commercial piezoelectric accelerometer made from Rochelle salt crystals and developed by Dr. Per V. Brüel Brüel & Kjær’s first lead zirconate titanate (PZT) accelerometer Brüel & Kjær’s standard reference accelerometer based on an inverted, centre‐ mounted compression design with quartz crystal piezoelectric element, ensured a high degree of accuracy for calibration This all‐titanium accelerometer was the first based on Brüel & Kjær’s patented DeltaShear™ design. Still in use today, the construction is regarded as one of the all‐time, classic accelerometer constructions The first miniature accelerometer with a PlanarShear design – extending the ...
