I-MON 256 DISB Interrogation monitor (1525 - 1570 nm)

The I-MON 256 DISB Interrogation Monitors offer realtime spectrum monitoring of Fiber Bragg Grating (FBG) sensors in the 1525-1570 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-411 electronics, the analoge 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
