Principle and Price of Fiber Optic Strain Sensors

Fiber and communications infrastructure knowledge brief Published 10 Oct 2021

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Fiber optic strain sensors typically range from a few hundred to several thousand USD per sensor, depending on type, packaging, and system requirements.

Price Range and Factors

The cost of fiber optic strain sensors varies widely based on sensor type, packaging, and application. Basic bare fiber FBG sensors are the most economical, suitable for direct installation, while packaged sensors with protective housings for industrial or harsh environments can cost 20–40% more than basic models due to enhanced durability and calibration requirements. Specialized sensors, such as displacement or acceleration FBG sensors, can be 2–3 times more expensive than standard temperature sensors because of complex mechanical assemblies and dynamic calibration needs.

High-definition fiber optic strain sensors, like Luna's HD6S, provide continuous, high-resolution measurements along the fiber and can measure over 1,000 distinct strain points per meter. These sensors are available in lengths up to 100 meters, and the cost scales with length and measurement density.

System Considerations

The sensor cost is only part of the total investment. Fiber optic systems require interrogators to read the sensor signals, which often represent 50–70% of the total system cost. Additional factors affecting cost include: Number of sensors per fiber (multiplexing reduces per-sensor cost)Measurement range and resolutionEnvironmental ruggedization and packagingIntegration with data acquisition systems and software support SummaryBasic bare fiber FBG sensor: hundreds of USD per unitPackaged FBG strain sensor: 20–40% higher than basic sensorsSpecialized sensors (displacement, acceleration): 2–3 times higher than standard sensorsHigh-definition continuous sensors (HD6S): cost depends on length and measurement density, potentially several thousand USD for long, high-resolution fibersInterrogator system: often 50–70% of total system cost Overall, fiber optic strain sensors are more cost-effective for large-scale or high-density monitoring compared to traditional strain gauges, especially when multiple sensors can be multiplexed on a single fiber.
