Quick Overview
- What it is: Triaxial piezoelectric accelerometer for simultaneous XYZ vibration measurements
- Typical Use: Modal analysis, structural vibration, automotive & aerospace R&D, calibration labs
- Status: Obsolete (out of production; may be available through surplus or secondary markets)
A Br�el & Kj�r 4520 Triaxial Accelerometer doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 4520, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
