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 suitable 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 1mV/ms-2 to 50mV/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. The current version now has quick links to the different sections, a matrix to simplify choosing the right equipment, and service/repair information.
