Fiber Optic Strain Gauges
Temperature Sensors (Fiber Optic)
The Model FP4700 Fiber Optic Temperature Sensors are designed for use in environments where high levels of electrical interference exist or where intrinsic safety is an issue. The FP4700 uses the temperature-dependent birefringence of a specially selected crystal as the temperature transduction mechanism. This crystal does not show thermal creep or aging as with some other fiber optic sensors.
