Accelerometers allow choice of three axes
A new family of robust triaxial accelerometers for vibration measurements in harsh industrial environments – the Type 4529 – has been developed by Bruel & Kjaer. Designed as a replacement for the company’s Type 4506 model, the Type 4529 family has a tougher design and wider frequency range.
They are nine times less sensitive to temperature fluctuations and 20 times less sensitive to base bending.
Another major difference is that the new accelerometer has a single-axis power supply, which allows much more flexibility. It means users can choose to measure with just one or two of the axes connected.
Being able to make single-axial and bi-axial measurements removes the need to connect all three channels, freeing up the data acquisition system for more accelerometers.
If only one or two axes are of interest, the ability to disconnect other axes also reduces unnecessary test complexity.
Having the flexibility to do this with the same accelerometer reduces the amount of accelerometers that testers need in their inventory.
Type 4529 has a range of mounting surfaces and a selection of clips, helping engineers to save on set‐up time and ensure accelerometers are correctly attached, making them ideal for structural testing.
These enhancements make the accelerometer suitable for use within a variety of application tests including aircraft, trains and satellites.
