Composite Sensor - Patch Strain Sensor

Strain sensor for composite structures

The Composite Patch Strain Sensor (FBGS-01CP) is a fiber optic strain gauge sensor specially designed for detecting defects in composite material before it reaches the sensor’s position. After being embedded inside the structure it measures the strain changes as a point inner deformation of structure. Thanks to this, the composite sensor enables you to minimize the detectable damage size and keep the critical parts of the structure under constant supervision.

100% passive sensor without the need of power supply
Made from various types of commonly used composite materials
Universal platform enabling the use of additional sensor types

The Composite Patch Strain Sensor uses the state of the art optical FBG approach based on a long-standing tradition of manufacturing composite, sandwich and bonded structures for the aerospace industry and terrestrial transport industry. This guarantees high performance, quality strength and durability of patches.

Features & Benefits

Improves the stress analysis of composite structure and precise predictions
Used as a standalone sensor or in series as part of a larger sensing network
Optional accessories, like fiber protection, customized size, 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.

Embedded monitoring

Optical sensor is designed to be embedded into the composite structure between the layers. The sensor enables to monitor bonded joints assembly, curing procedure and their behavior during the service.
