FiberSensing FS 6500 FBG accelerometer

Bestech Australia has released the FS 6500 FBG accelerometer from FiberSensing.

This single-axis device is a fibre-optic version of the conventional accelerometer but passive, offering inherent insensitivity to environmentally induced noise. It is specifically tailored for applications requiring the measurement of low frequency and small amplitude accelerations.

The device was designed to allow outdoor installation under severe conditions and with no extra protection. The robust design meets the IP68 protection standards and includes an aluminium case and input and output fibre-optic armour cables.

It is claimed to provide high accuracy and high resolution measurements, and total fibre-optic design ensuring intrinsic immunity to electric sparks and EMI/RFI and no ignition risk.

The high sensitivity and linearity as well as the flat frequency response and low transverse sensitivity of this new accelerometer make it suitable for a large range of monitoring applications, such as ambient vibration monitoring of civil structures.

Compatible with most standard FBG measurement units, the accelerometer combines compact size and high resistance to corrosion and harsh environments with long-term reliability.
