| Multi-point fiber grating string (array) |
| Fiber type | SMF-28E |
| Writing method | Mask |
| Center wavelength | 1525nm to 1565nm or According to customer needs |
| Reflectivity | 10% to 99% |
| Temperature range | -40 to 150 degrees Celsius (this product can be used repeatedly at 150 degrees, but it can not be placed at this temperature for a long time. It can be used continuously for a long time in default temperature) |
It has high sensitivity, fast heat transfer, good accuracy, small volume, lightweight, high tensile strength,
high-pressure resistance, high-temperature resistance, waterproof and moisture-proof, no combustibles,
corrosion resistance, etc.
Using the temperature measurement characteristics of the Bragg grating (FBG), the sensor can be probed,
stuck, surfaced, glued or embedded in the structure to be tested for temperature detection and monitoring.
It can be widely used in industrial production, power, railway, military, aerospace and other fields of single-point
or quasi-distributed temperature measurement.
