Fiber Optic Grating Strain Sensor Quotation

Fiber Bragg Grating (FBG) strain sensors are available in various configurations for surface, embedded, or distributed strain measurement, and quotations can be requested directly from specialized suppliers.

Sensor Types and Applications

1. Surface-Mount and Embedded Sensors

• Surface-mounted FBG sensors are glued or attached to structural surfaces to measure strain directly at the contact point, suitable for buildings, bridges, and mechanical components .
• Embedded sensors, such as those for concrete or reinforced concrete, are designed for long-term internal strain monitoring and structural health analysis . 2. Quasi-Distributed and Multipoint Arrays
• FBG arrays allow multiple gratings on a single fiber for simultaneous multipoint strain measurements, reducing cabling and installation time .
• These arrays can be customized for the number of FBGs, spacing, wavelengths, cable types, and protective coatings, making them suitable for laboratory and industrial applications . 3. Temperature Compensation
• Many FBG sensors include dual-grating designs or push-pull configurations to compensate for temperature effects, ensuring accurate strain readings .

Installation and Mounting Options

• Adhesive bonding for flat or slightly curved surfaces
• Embedding in concrete or composite materials
• Stainless steel or polymer packaging for rugged environments
• Series or parallel connections for quasi-distributed networks
