Grating manufactures FBG sensing systems and Distributed Optical Fiber Sensing (DOFS) solutions.

Their FB

G systems are based on the wavelength reflection principle, providing short-distance fixed-point or quasi-distributed temperature measurements. These systems are suitable for industrial monitoring, structural health, and harsh environments. 3.

Polytec Polytec offers FBG interrogators and fiber optic temperature sensors with high spatial resolution and wide temperature ranges (from cryogenic to +600°C). Their systems, such as the si155 and HYPERION platforms, support hundreds of FBGs or Fabry-Perot sensors, providing real-time, dynamic, and static measurements. Polytec's sensors are robust, EMI-resistant, and suitable for harsh industrial conditions.

Features and Capabilities

High precision and sensitivity: Sub-millimeter spatial resolution and temperature resolution up to 0. 1°C. Multipoint and distributed sensing: Ability to monitor multiple points along a single fiber or over long distances.

Harsh environment compatibility: Resistant to electromagnetic interference, extreme temperatures, and mechanical stress. Flexible installation: Can be embedded in structures, batteries, or industrial processes where traditional sensors cannot be used. Interrogator systems: Provide real-time readout, data acquisition, and analysis for FBG arrays or distributed fiber networks.

Applications
