Displacement sensor

Displacement sensor for structures monitoring

The Displacement sensor is a fiber optic displacement sensor specially designed for long term monitoring of structures. It uses the state of the art optical FBG technology and keeps the critical infrastructure under constant supervision. The sensor is a fiber optic equivalent of a potentiometric, inductive or capacitive displacement gauges.

  • 100% passive sensor without the need for power supply
  • temperature compensated design
  • universal platform enabling the use of additional sensor types

100% passive sensor

Since the sensor does not need the power supply, it easily monitors places without access to the power and hazardous or inaccessible areas.

Temperature compensation

This FBG sensor is designed to minimize parasitic temperature dependence.

Universal platform

The strain sensor can also be used in combination with other sensors, such as temperature, inclination, vibration, strain, etc.

Protected as IP68 rated devices

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

Connectivity

The sensor can be used alone or incorporated into a large sensing network regardless of sensor interconnections.

Installation costs

Installation and cabling for optical sensor networks are much less expensive and cumbersome than comparable electronic gauge networks.

Immune to EMI/RFI

The sensor enables operation even in harsh environments and hazardous areas. The advantage is immunity to electromagnetic/radio frequency interference.

Leverage the existing fiber optic network

Standard telecommunication optical fibers, for example, dark fibers, can connect the unit and sensors. This is very economical even for a large number of monitored points.

Supplied with mounting plates

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.

Advanced customization available

The sensor can be customized for your project, for example replacing metal parts with plastics for high-voltage environments.
