FBG Strain Sensors

S1

Sensor can be welded directly to the surfaces of metal structures (pipes, beams and other metal supports steel surface). Possesses protective silicone cover.

Details

S2

Sensor can be attached by adhesive to the test surface (pipes, beams, metal supports, composite and plastic materials).


Details

S3

Sensor can be used in concrete construction. Attached to a metal armature sensor is able to feel even the slightest deformation of reinforced concrete structures.

Details

S4

Sensor has an innovative design that provides the sensor operating at high temperatures and improves overall stability and scalability of the system.

Fiber optic strain gauge is welded directly into the surface of the metal structure (pipes, beams, etc.), and it has a protective silicone cover.Fiber optic strain sensors are durable and stable, widely used for civil engineering constructions, particularly they reinforce concrete structures exceptionally well.

Fiber Bragg Grating strain sensors demonstrate lots of advantages compared to the regular electrical strain gauges. Namely, they are immune to electromagnetic interference and power shortages. Compact size devices provide the most accurate measurements. FBGs are, literally, the best strain sensors right now.
