Features:

  • Long-term vibration resistance: 2g
  • Wide temperature range: -20~65°C
  • Convenient communication interface: RJ45 (TCP/IP, Modbus), CAN
  • Fully integrated: Built-in complete web-based configuration management system

Application:

  • FBG/FP sensor detection and long-term online monitoring
  • Infrastructure, turbines, equipment: stress, strain, structural damage

FBG interrogator is resistant to long-term vibration, data interface is resistant to high voltage, wide temperature range, flexible and convenient communication interface, and built-in complete web-based management system.

The interrogator has passed a series of reliability tests such as vibration, shock, humid heat, alternating temperature, electromagnetic compatibility and salt spray, and the product is safe and reliable, and has been in operation Mature use.

The products can also be applied to bridges, tunnels, petroleum and petrochemical, power grids, marine and aviation fields based on FBG or FP fiber optic sensors and other physical quantities based on FBG or FP fiber optic sensors for high-precision measurement.
