newLight FS65 Optical Accelerometer for Low Frequencies

Based on the Fiber Bragg Grating (FBG) technology and the newLight optical sensor line, the FS65 accelerometer is a high precision vibration sensor tailored to measure acceleration at different frequencies from 0 to 50Hz.  

The accelerometer can be used in a large range of monitoring applications where low frequency, but relevant amplitude vibrations are present, including measuring load induced vibration of civil structures and ambient cable vibrations. The simultaneous measurement of vibration along different axes is possible using multiple accelerometers.

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


  • 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 materials with high levels of strain
