Displacement sensor

Displacement sensor for continuous structure behavior monitoring

The Displacement Sensor (FBGD-01) is a fiber optic displacement sensor specially designed for long term monitoring of structures behavior. It uses the state of the art optical FBG approach and keeps the critical infrastructure still under supervision. The sensor is a fiber optic equivalent of a potentiometric, inductive or capacitive displacement Gauges

  • 100% passive sensor without the need of power supply
  • Temperature compensation design
  • Universal platform enabling the use of additional sensor types

The Displacement Sensor is supplied with mounting plates which facilitate direct mounting on the surface of a monitored structure. In this way, the fiber sensor makes direct contact with the surface and therefore accurately measures the displacement changes between two points in the range of 50 mm.

Features & Benefits

  • Lower costs on installation and cabling
  • Used as a standalone sensor or in series as part of a larger sensing network
  • Advanced customization possible

Protected as IP68 rated devices

The IP68 rating guarantees complete dust-tightness and protection against the effects of long periods of immersion in water.

Immune to EMI/RFI

The sensor enables operation even in harsh environments, as the technology is fully passive, explosion safe and immune to electro-magnetic/radio frequency interference.

Leverage existing fiber optic network

The connection between unit and sensors is ensured via standard telecommunication optical fibers (e.g. dark fibers), which is very economical even for a large area of monitored objects.
