FBG Interrogators and Sensors
Fiber Bragg Gratings (FBG) interrogators are the main components of systems that allow measurements, simultaneously and at several points along the same optical fiber, of different parameters, such as temperature, strain, pressure displacement, acceleration…
Our measurement units are designed to provide the best cost to performance ratio. The fully modular concept of measurement units allows you to configure and optimize the performance and, therefore the cost, to suit your specific needs.
We offer a broad range of interrogators:
- 4, 8, 2×4, 16 independent optical channels
- Scan frequency 20-200 Hz, 100-1000 Hz, up to 3 kHz
- Spectral ranges 1500 nm to 1600 nm
- Resolution / Repeatability <1pm
- Short-term accuracy +/- 2 pm
- Absolute Accuracy (Long term) +/- 4 pm
- Dynamic range 20 dB to 50 dB
- Communication interfaces RS232, RS485, CAN Open, USB 2.0, Ethernet IP, GPRS …
- Data Logging 128MB to 1GB
