Technical Paper 1

Technical Paper 2


The T160 is a single-mode fiber (SMF) based multipoint Fiber Bragg Grating (FBG) sensor for environments to 1,000°C.

Available in a wide range of optical specifications. Annealed up to 1,100C, or produced without annealing, as the application requires. Naturally packaged (written) directly in fiber, these sensors can be used as they are or they can be packaged into a variety of higher level sensors for use in optical sensing systems. Small-size and fast response time. Excellent wavelength to temperature linearity after annealing or regeneration. The T160 FBG sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG sensors. EMI immune.

T160 series FBG sensors are fabricated using licensed and proprietary state-of-the-art laser manufacturing technologies and thermal designs in a variety of fibers, coatings and protection materials to fit a wide range of high-temperature applications.

Key Features:

Designed for applications to 1,000 Degrees Celsius. Factory annealing and regeneration for systems requiring pre-calibrated FBG sensors that are ready to measure out of the box; also available without annealing for applications that require a high-level of fiber flexibility during installation. Configurations for one-time setups or multi-use.

Sensor specification options. The precision made FBG structure written into the fibers’ core for producing the T160 yields a simple transducer configuration of high resolution, linearity, and measurement repeatability. High SLSR and customer specified BW for clear signal processing. Sensor length and spacing option.

High temperature protection options. The T160 is Coated/protected with heat resistant polyimide, gold, steel, or delivered in bare fiber format for secondary OEM packaging. Well fit for optical sensing systems that are required to operate in environments up to 1,000°C, ideally balancing cost, performance, and reliability for creating new and attractive commercial solutions.

Multi sensor array. Well suited for projects that include the need to monitor high temperatures distributed at many points. The T160 can be provided in FBG arrays or cables of various lengths with a customer defined number of embedded FBGs.

Ready for OEM designs. The T160 is a multipoint sensor that can be used AS IS or can be further packaged into higher level sensors. Inquire with us about high-temperature FBG arrays in OEM fibers, OEM coatings, and OEM packaging.
