K-OP-A: Armored Optical Sensors Chain for Harsh Environments

The K-OP-A measurement chain is a configurable array of optical FBG (Fiber Bragg Grating) sensors that withstand extremely harsh operating conditions. Such conditions can likely damage the adhesive bond of classic optical strain gauges.

A K-OP-A chain of optical sensors can integrate in a single optical fiber both, OL-WA linear weldable gauges, well-suited for high-strain applications, and OR-WA weldable rosettes, which measure strain at different points and directions.

Suitable to be spot welded to steel structures and materials, the K-OP-A sensors feature rugged fiber leads with armored cable protection.

In addition, OL-WA linear gauges can be used for temperature compensation of other optical strain sensors. The only requirement is to weld them to a steel body (OTC-WA-Plate) that can be ordered together with the sensor.

 

Example of a configured chain:

Passive

  • Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc.)
  • Electrical isolation

Safe operation in hazardous environments (e.g. potentially explosive environments, high voltage areas and intense electromagnetic fields)

Extremely Robust

  • Stainless steel packaging and steel-reinforced coating
  • Outstanding bending capability (6 micron core fiber)

Accurate results during 24/7 operation in aggressive atmospheres and under harsh environmental conditions, even on curved surfaces

Reliable

  • Based on the measurement of an absolute parameter - the Bragg wavelength - independent of power fluctuations

Self- referenced meaning: high quality measurements with long-term stability

Easy to Install

  • Easy installation by simple spot welding method

Long service life with a permanent non-degradable attachment to the structure material
