I-MON 256 C DISB Interrogation monitor (1520 - 1579 nm)

The I-MON 256 C DISB Interrogation Monitors offer realtime spectrum monitoring of Fiber Bragg Grating (FBG) sensors in the 1520-1579 nm wavelength range. High spectrometer resolution combined with broad wavelength range provides high resolution interrogation monitors allowing measurement of a large number of FBG sensors.

Equipped with Ibsen DISB-400 electronics, the analouge video output from the detector is converted to a 16-bit digital signal that can be read over the SPI interface.

Applications

  • Vibration analysis
  • Temperature measurements
  • Pressure monitoring
  • Strain measurements
