newLight FS65HSA High Sensitivity Accelerometer for Ambient Vibrations

The newLight FS65HSA is an advanced vibration sensor based on Fiber Bragg Grating (FBG) technology. It is part of the newLight optical sensor line and is designed to measure extremely low acceleration levels at low frequencies with exceptional sensitivity.

Ideal for a wide range of monitoring applications, the FS65HSA excels in detecting low-frequency, small-amplitude vibrations. It is particularly suited for ambient vibration monitoring of civil structures, aiding in structural health monitoring.

The sensor is self-compensated for temperature variations, ensuring stable measurements at very low frequencies. The simultaneous measurement of vibration along different axes is possible using multiple accelerometers, connected together and installed at different positions.

Safe and robust

Ruggedized packing with IP68 casing and electrical passiveness makes it suiteable for potentially explosive atmospheres, high voltage areas, and intense electromagnetic fields

Effective even under aggressive environments and adverse conditions such as humidity and salt

Versatile

In-series connection with other accelerometers for bi- or tri-axial measurements

Dual output for in-series integration

Highly sensitive

Linear sensitivity and impressive full frequency flatness

Accurate measurements even in very stiff structures under ambient vibration
