Bruel and Kjaer has broadened its vibration sensors product range by adding more than 50 new types of products including various accelerometers, force transducers and hammers.

The new product expansion reflects Bruel and Kjaer's renewed commitment to offer the most comprehensive line of high-performance, high-quality, economical, rugged and lightweight uniaxial and triaxial sensors for almost any application.

The company also supplies a wide variety of quality connectors, cables and mounting options that ensure optimum measurement integrity, ease of setup and data reliability.

The product range expansion has been developed to meet the company's growing customer demands for precision instrumentation.

Bruel and Kjaer has increased its focus on product development, testing and quality to provide customer-dedicated solutions as well as a high level of pre- and after-sales support.

To support the new product developments Bruel and Kjaer has invested in new production facilities in Denmark.

The new manufacturing capability enables the company to react faster to market and customer demands for precision instrumentation and also gives the opportunity to perform exacting tests on new designs to fully optimise product quality.

Bruel and Kjaer has also strengthened its dedicated team of in-house engineering staff to support its continuous development of new accelerometers and sensors.

Building on the many years of Bruel and Kjaer experience and knowledge the increased in-house engineering department adds capacity not only to improve existing accelerometers, but also to develop new versions and make customer-specific variants of existing designs.

Two of the first products to emerge from the new accelerometer development programme are the miniature triaxial DeltaTron accelerometer Type 4524, which is ideal for automotive applications, and the DeltaTron accelerometer Type 4511 developed to address aerospace requirements.

The miniature triaxial DeltaTron accelerometer Type 4524 a new lightweight, triaxial, piezoelectric, OrthoShear accelerometer addresses the needs of the automotive industry and is suitable for: structural analysis measurements; multichannel modal analysis measurements as well as modal measurements for automotive body and powertrain applications.

Ideal for use by civil and military helicopter manufacturers, the piezoelectric DeltaTron accelerometer Type 4511 is flight-test certified.

All the Type 4511 processes and materials comply with MIL-STD-11268.

The device's primary design objective has been reliability under extreme conditions, yielding very high robustness versus mechanical, electrical and environmental influences.

Applications include: flight test; measurement in harsh environments; health usage monitoring systems (HUMS); and gearboxes.

Both the Type 4524 and Type 4511 accelerometers were developed using finite element modelling.

Each accelerometer is individually calibrated and supplied with a comprehensive calibration chart, using state-of-the-art, random FFT technology, providing an 800-point, high-resolution calibration (magnitude and phase), ultimately giving a unique characterisation and securing the integrity of the vibration measurement.
