The HBM FiberSensing FS63 Temperature Sensors are Fiber Bragg Grating (FBG) based sensors, designed to be bonded to surfaces and materials, spot welded to structures and components, attached or directly cast into concrete wet mix.

HBM FiberSensing temperature sensors are particularly suited for temperature measurements in large structures, such as Structural Health Monitoring (SHM) in civil structures and thermal mapping in electrical machines. They can also be used for thermal compensation of other optical sensors.

Key Benefits

• Robustness: Long-term reliability ensured by innovative sensor design, careful selection of materials and IP68 packaging.
• Completely passive: Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc.) and safe operation in hazardous environments.
• High multiplexing capability: Connection of a large number of sensors to a single optical fiber, reducing network and installation complexity.
• Remote sensing: Large distance between sensors and interrogator (several kilometers).
• Compatible with most interrogators: Provided with calibration sheet, allowing easy and accurate configuration.
• Self-referenced: Based on the measurement of an absolute parameter – the Bragg wavelength – independent of power fluctuations.

FS63 – High Temperature Dielectric Probe

The FS63 – High Temperature Dielectric Probe is a Fiber Bragg Grating (FBG) based sensor, specifically designed to withstand high temperatures and intense electromagnetic fields.

This sensor is completely non-metallic and employs only heat-resistant and highly dielectric materials.

Special Key Benefits of FS63 High Temperature Dielectric Probe:

• Robustness: Ruggedized construction with Kevlar® and PTFE strength layers, offering high longitudinal and transversal protection.
• High multiplexing capability: Possibility of connecting several sensors to the same optical channel in a single interrogator, by using active and/or passive multiplexers.
