High Sensitivity Accelerometer for ambient vibrations.

This advanced optical accelerometer uses FBG technology to detect extremely low acceleration levels at low frequencies with exceptional sensitivity. Ideal for structural health monitoring, it excels in measuring small-amplitude vibrations in civil structures under ambient conditions, as well as larger excitation levels up to ±5g. Temperature compensation ensures stable performance, and multiple sensors can be combined for multi-axis monitoring.

Ultra-Sensitive

Detects extremely small movements at low frequencies, making it ideal for ambient vibration monitoring in large structures. When paired with MXFS DI, it achieves a resolution of 0.25 μg/√Hz across a 1000 Hz bandwidth, delivering exceptional sensitivity. The temperature-compensated design ensures consistent accuracy under varying environmental conditions.

Scalable

Combine sensors for bi- or triaxial measurements, offering advanced structural health monitoring capabilities.

Versatile Application

Combines very high resolution with a large measurement range, making it suitable for both ambient vibration and excited vibration load tests.
