Anchor Sensor - Long gauge strain sensor

Anchor sensor

Strain sensor for structure behavior monitoring

The Strain Sensor (FBGS-01-AN) is a fiber optic strain long gauge sensor specially designed for long term monitoring of structures behavior using the state of the art optical FBG approach. It allows you continuous structural health monitoring and to keep the critical infrastructure under constant supervision. The sensor is a fiber optic equivalent of an electrical strain gauge, which can be mounted directly on the surface or inside the structure

  • 100% passive sensor without the need of power supply
  • Tension and compression monitoring of any structure
  • Universal platform enabling the use of additional sensor types

The Anchor Sensor is supplied with two specially designed anchors which facilitate a fixing to the structure. In this way, the fiber sensor makes direct contact with the construction and therefore accurately measures the strain of the monitored object. The strain changes are measured as elongation, compression or bending of a fiber between two fixed points.

Features & Benefits

  • Lower costs on installation and cabling
  • Used as a standalone sensor or in series as part of a larger sensing network
  • Optional accessories like sensor protective cover, customized mounting anchors, connectors etc.

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