Product Overview:
The OFSCN® 350°C capillary seamless steel tube distributed fiber optic temperature sensor consists of an optical fiber connector, stainless seamless steel tube, and 350°C high-temperature resistant single-mode/multi-mode optical fiber encapsulation. This product features high sensitivity, fast thermal conductivity, good accuracy, compact size, light weight, high tensile strength, high compressive strength, high temperature resistance, and non-combustibility.
This sensor is suitable for various distributed fiber optic temperature sensing systems (DTS), including but not limited to Brillouin scattering (BOTDR, BOTDA, BOFDR, etc.) fiber optic temperature measurement systems, Rayleigh scattering and Raman scattering (FOTDR, FOFDR, ROTDR, ROFDR, etc.) fiber optic temperature measurement systems. Essentially, this sensor is a universal product and does not have compatibility issues with demodulation equipment.
Users and engineering companies can insert, clip, surface mount, glue, or embed this sensor into the structure to be measured for temperature detection and monitoring. The OFSCN® 350°C capillary seamless steel tube distributed fiber optic temperature sensor can be widely used in distributed temperature measurement in industries such as industrial production, power, railway, military, aerospace, and energy etc..
Although this product is defined as a 350°C product, it can be repeatedly used within the range of 400°C to 450°C (and can be continuously used in a 350°C environment).
