  • Relative or absolute pressure measurement.
  • Customizable for different pressure ranges (1, 4, 7, 10, 15 and 20 bar)
  • 2-fiber port configuration allowing for chain
    formation with a variety of FBG-based
    sensors on single fiber line
  • Ruggedized housing suitable for harsh
    environments
  • Extremely small drift (<0.5%FS/year)
  • Very high accuracy and stability

Application



  • Water height monitoring
  • Pore water pressure measurements
  • (Hazardous) tank monitoring
