While there is no known Ethiopia-based manufacturer, international suppliers like Luna, AtGrating, Optromix, FBGS, and Scaime provide high-quality Fiber Bragg Grating (FBG) strain gauges suitable for use in Ethiopia.

Key International Suppliers

1. Luna Innovations (os3100 series) Luna offers the os3100 optical strain gage, which uses FBG technology for precise strain measurement. It can be mounted via spot welding or epoxy, provides high fatigue life, and is suitable for harsh environments. Luna also offers temperature compensation options and integrates with the HYPERION interrogator for real-time monitoring . 2. AtGrating AtGrating specializes in FBG sensors for strain, pressure, temperature, displacement, and tilt. Their sensors are widely used in civil engineering, energy pipelines, aerospace, and medical applications. They provide full technical support, installation guidance, and customization options for distributed sensor networks . 3. Optromix Optromix produces FBG strain sensors that can be welded or embedded into metal and composite structures. Their sensors allow simultaneous strain and temperature measurement and are designed for civil engineering applications such as bridges, tunnels, and pipelines . 4. FBGS FBGS offers a variety of fiber optic strain gauges, including single sensors (SG-01) and configurable chains (SGC-01) for monitoring strain distribution. Their products are suitable for harsh environments and can be installed on-site or in laboratories . 5. Scaime Scaime provides a complete range of fiber-optic strain sensors for civil, industrial, and hazardous environments. Their sensors are immune to electromagnetic interference, suitable for long-term monitoring, and can be installed in complex structures like hydroelectric plants, offshore platforms, and aircraft fuel tanks .

Considerations for Ethiopia

• Shipping and Support: International suppliers typically ship to Ethiopia and may provide remote technical support.
• Applications: FBG strain gauges are ideal for structural health monitoring, civil engineering projects, and industrial installations.
• Installation: Sensors can be surface-mounted, embedded, or welded depending on the structure and monitoring requirements.
• Customization: Many suppliers offer tailored solutions for distributed sensing networks and multi-point monitoring. For Ethiopian projects, contacting these international suppliers directly is recommended to discuss shipping, installation support, and sensor customization to meet local infrastructure needs.
