Fibre Optic Accelerometer

Supplier: Bestech Australia

Bestech Australia is pleased to present the FS 6500 FBG accelerometer, from FiberSensing.

Price Guide: POA

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

This new accelerometer was designed to allow outdoor installation under severe conditions and with no extra protection. The robust design of this sensor meets the IP68 protection standards and includes aluminium case and input and output fibre optic armour cables. It provides 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 suited to a large range of monitoring applications, such as ambient vibration monitoring of civil structures.

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

It is also suitable for remote sensing, with it being possible to locate the sensor several kilometres away from the measurement unit. It offers intrinsic multiplex capability that allows the concatenation of a large number of sensors in a single optical fibre. This accelerometer is therefore particularly suitable for difficult-to-reach locations and large scale sensing networks.

Accessories allow a compact, in series mounting of two or three accelerometers in transversal directions for measuring vibration simultaneously along multiple axes.
