Brüel & Kjær Introduces New Line of Tough Vibration Measurement Accelerometers

Press Release:
  Aug 7, 2013 — Brüel & Kjær has created a range of robust CCLD accelerometers for vibration measurements in harsh industrial environments.

The new Type 4533-B and Type 4534-B accelerometers feature a high signal output-to-weight ratio and very low sensitivity to environmental influences thanks to Brüel & Kjær’s patented ThetaShear® accelerometer design.

This makes them ideal for general vibration measurements for a range of different applications, such as automotive parts, aircraft, and industrial machinery.

The new units have output sensitivities from 1 mV/ms–2 to 50 mV/ms–2 and a non-destructive (shock) limit of 10 000g, making them more robust than normal CCLD accelerometers, which typically have a limit of 5000g.

Both accelerometers automatically self-identify and supply calibration information using TEDS technology (Transducer Electronic Data Sheet).

Each unit features lightweight, robust, hermetically-sealed titanium housing, an insulated base (avoiding ground-loop problems) and a 10–32 UNF thread mounting hole - suiting use in harsh environmental conditions.

Brüel & Kjær has also updated its Transducers & Conditioning catalogue, which provides a comprehensive guide to its full range of microphones, accelerometers and accessories.

This latest version has quick links to the different sections, a matrix to simplify choosing the right equipment, and service/repair information.

More information about 4533-B and 4534-B is available on Brüel & Kjær's web site:
