Fibre Strain Gauge Chain

The Strain Gauge Chain SGC-01 is a spliceless chain of several fibre optic Strain Gauges in series. These Strain Gauges are the fibre optic equivalent of electrical strain gauges. The Strain Gauges can be mounted directly on the surface of a structure by means of an adhesive. In this way, the fibre sensor makes direct contact with the surface and therefore accurately measures the strain at the surface. Supply of the installation tools and instruction manual can all be found in the Strain Gauge Installation Kit (SGK-01).

Key Features

• Single fibre cable containing multiple sensing points
• Fully configurable according to customer needs
• High strength sensors offering excellent fatigue resistance
• Direct attachment of the sensors to the surface(s) to be monitored

Primary Applications

• The Strain Gauge Chain SGC-01 is used to measure strain changes (due to tension, compression and bending) on the surface of metallic or composite structures under test, at multiple positions employing only a single optical fibre.

In this way, an entire strain distribution can be monitored with a single fibre cable so that the loads which act upon the structure can be deduced. In combination with high speed interrogators from FBGS, vibration analysis can be performed also.
