Geokon’s new Model FP4000 Fiber Optic Strain Gage is built around the proven Opsens OSP Fiber Optic Strain Gage Sensor. The gage uses 2 optical fibers precisely aligned inside a micro-capillary tube to form an optical Fabry-Perot interferometer.
These gages have been designed for the measurements of strains on steel and in concrete, where it may be difficult to use other types of strain gages because of space limitations, high levels of electrical noise or where intrinsic safety is an issue.
The gages are available in 3 ranges, ±1000 microstrain, ±2500 microstrain and ±5000 microstrain.

For optimum accuracy it is recommended that the Model FP4700 Fiber Optic Temperature Sensor, of similar construction, be installed alongside the Strain Gage to provide for precise temperature measurements (and compensation).
The FP4000 Strain Gage is immune to EMI, RFI and voltage surges (lightning). It is insensitive to transverse strains, capable of signal transmission over long distances and suitable for both static and dynamic measurements.
The readout device recommended for basic field measurements is the PicoSens single channel battery operated handheld signal conditioner.
Where multiple gages are to be monitored the FieldSens Multi-channel, signal conditioner is recommended.
