OFSCN® Fiber Bragg Grating (Fiber Optic Grating) Temperature Sensor Overview Video:
It is a FBG sensor with insulation, high sensitivity, fast thermal conduction, good accuracy, small size, light weight, high-temperature resistance, waterproof and moisture-proof properties, non-combustible characteristics, and corrosion resistance.
By utilizing the temperature measurement characteristics of the FBG, this sensor can be inserted, clamped, surface-mounted, or adhesive-bonded to the measured structure for temperature detection and monitoring. It can be widely used in industrial production, power, railway, military, aerospace, and other fields for single-point or quasi-distributed temperature measurement.

The OFSCN® Ceramic Packaged Fiber Bragg Grating Temperature Sensor can package both single-point and multipoint fiber bragg gratings (FBGs).
By selecting FBGs with different temperature resistance grades, the product can adapt to temperature environments ranging from -200°C to 800°C. In terms of principles and actual measurements, this FBG temperature sensor is a universal product and does not have compatibility issues with FBG demodulation equipment. When used with a matching FBG demodulator, the product can also be called an industrial-use capillary thermometer.
