Product Overview of the 300℃ Fiber Bragg Grating Temperature Sensor:
OFSCN® 300℃ Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor consists of fiber connectors (FC, SC, LC, ST, etc.), stainless steel seamless tube, and single-point/serial fiber Bragg grating (FBG) encapsulation. The FBG is written using the ultraviolet light masking method, and the fiber used is polyimide-coated fiber.
It is a FBG sensor with high sensitivity, fast heat conduction, good accuracy, small size, light weight, high tensile and compressive strength, high temperature resistance, waterproof and moisture-proof properties, non-combustible, and corrosion resistance.
By utilizing the temperature sensing characteristics of the Bragg fiber grating (FBG), this sensor can be inserted, clamped, adhered, or embedded into the structure to be tested for temperature detection and monitoring. It can be widely used in various industries such as industrial production, chemical industry, power, railway, military, aerospace, for single-point or quasi-distributed temperature measurement.

OFSCN® 300℃ Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor can be encapsulated with a single-point FBG or a serial FBG string/array.
This product is currently defined as a 300℃ product, encapsulating a FBG fabricated using the ultraviolet light masking method, with a polyimide coating that allows long-term use in a 300℃ environment (can be repeatedly used at 370℃).
In terms of principle and actual measurement, 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, this product can also be referred to as an industrial capillary thermometer.
