Product Overview of Femtosecond FBG Temperature Sensor:
OFSCN® 500°C capillary seamless steel tube FBG temperature sensor consists of fiber connectors (FC, SC, LC, ST, etc.), stainless steel seamless tube, and single-point/serial femtosecond FBG encapsulation. The FBG is written using femtosecond laser point-by-point inscription technique, and the fiber used is doped polyimide fiber.
It is a FBG sensor with high sensitivity, fast thermal conduction, good accuracy, small size, light weight, high tensile strength, high compressive strength, high temperature resistance, waterproof and moisture-proof, non-combustible, and corrosion resistance.
By utilizing the temperature measurement characteristics of the FBG, this sensor can be inserted, clamped, attached, glued, or embedded into 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.

OFSCN® 500 degrees Celsius capillary seamless steel tube FBG temperature sensor can be encapsulated with a single-point femtosecond FBG or a multi-point femtosecond FBG string/array.
This product is currently defined as 500 degrees Celsius, which is related to the fiber quality and FBG quality. The product is encapsulated with femtosecond FBG and can be used for long-term applications in a 550 degrees Celsius environment (recommended temperature range from -200 degrees Celsius to 500 degrees Celsius, and it can be used repeatedly at higher temperatures, but temperatures above 600 degrees Celsius are not recommended, and the required product temperature should be specified when placing an order).
In terms of principle and actual measurements, this FBG temperature sensor is a universal product, and there is no issue with the compatibility of FBG demodulation equipment. With the matching FBG demodulator, this product can also be called an industrial-capillary thermometer.
