  • Brüel & Kjær’s radiation-resistant accelerometers

    Carrying out vibration measurements in harsh industrial environments is much easier for engineers with Brüel & Kjær’s new Type 8347-C Accelerometer. The Type 8347-C accelerometer can withstand temperatures ranging from -196°C (-321°F) to +482°C (+900°F) and has high resistance to radiation. The shear design ensures the accelerometer  superior thermal ...

  • Brüel & Kjær accelerometers - 65 years of excellence

    The Thirties Already before the two young engineers Per V. Brüel and Viggo Kjær graduated as Masters of Electrical Engineering in 1939, they had decided to start a company together. However, they felt it was necessary to learn more and get some practical experience before actually going ahead, so P.V. Brüel became assistant to professor P.O. Pedersen in the newly created ...

  • Calibration – the sure way to accurate measurements

    Calibration   During testing, microphones and accelerometers can change sensitivity or break. They might look intact, but what happens if you continue measuring without having calibrated your transducer? Can you trust your data? Do you have to redo the entire test? In cases of extreme testing you might only have one shot at getting your measurement right as the product gets ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

  • Inalfa - production testing of sunroof systems

    Production Testing of Sunroof Systems Sound and vibration are growing in importance as critical factors in product quality. Therefore, manufacturers are required to perform noise and/or vibration quality testing prior to shipping a product. The proper implementation of such a test is a significant challenge – one that can offer a very large return on investment. To address this ...

  • Sonic booms – environmentally friendly?

    JAXA and Brüel & Kjær Join Forces to Measure Sonic Booms Brüel & Kjær and JAXA join forces in a research project to measure sonic booms. Side-by-side with JAXA’s ABBA sonic boom system, Brüel & Kjær’s PULSE LAN-XI based data acquisition and analysis system is used to study the effects of sonic booms on buildings. When ...

  • Helping Volvo maximise uptime

    With the many challenges facing the automobile industry, such as shortened development times, Volvo is increasingly moving its Noise, Vibration and Harshness (NVH) development into computer simulation and modelling, with less traditional prototyping. A well-established customer of Brüel & Kjær, Volvo benefits greatly from the value added to their systems in terms of the minimised ...
