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.
- For spot welding, the Heller c30 Impulse Welding Device is recommended (not available in the US).
