K-OP: Optical Sensors Chain for High-Strain Measurements

The K-OP measurement chain is a configurable array of optical FBG (Fiber Bragg Grating) sensors for high- strain applications. This time-saving setup will be shipped pre-configured for easy installation.

A K-OP chain of optical sensors can integrate both, linear strain gauges and rosettes, which measure strain in different points and directions, in a single optical fiber. It meets the requirements of modern materials with particularly high deformations, flexibility, and fatigue.

Sensors are available for gluing as well as welding. In addition, variations for extreme temperature ranges and for compensating the effects of temperature on strain measurements are available.


Example of configured chain:


  • Accurate measurement on curved surfaces
  • Long-term stability without drift
  • Thermal effect accurately compensated
  • Immunity to all electromagnetic interferences (EMI, RFI, sparks, etc.)
  • Extended temperature range versions available

Very precise measurement results with long-term stability


  • Patented sensor design with outstanding bending capability
  • High resistance to fatigue under high alternating loads
  • Plastic and stainless steel packing
  • Resistance to corrosion, even in humid and salty environments

Extremely resilient and suited for laboratory applications


  • Pre-configured sensor chain, ready-to-install
  • Light-weight optical fibers and reduced cabling
  • Simple installation similar to other strain gauges
  • Fitted for hybrid measurements (optical and conventional) using catman® software
  • Straightforward and automatic configuration for data acquisition

Universal and easy to use with little installation effort
