Stainless Steel Seamless Tube Encapsulated Fiber Bragg Grating Temperature Sensor

The stainless steel seamless tube encapsulated fiber Bragg grating temperature sensor is a fiber grating sensor featuring high sensitivity, fast thermal response, excellent accuracy, as well as small size, light weight, high tensile strength, high compressive strength, high temperature resistance, waterproof and moisture-proof properties, non-combustible materials, and corrosion resistance.

Utilizing the temperature measurement characteristics of Fiber Bragg Gratings (FBGs), this sensor can be inserted, clipped, surface-mounted, adhesively bonded, or embedded into the structure under test for temperature detection and monitoring. It is widely applicable for single-point or quasi-distributed temperature measurement in industrial production, chemical industry, electric power, railway, military industry, aerospace, and other fields.
