Characteristics
  • MSA-01 is a strain array sensor with variable number of FBG sensors (min = 1, max = custom) and various gauge lengths.
  • Effectively replacing numbers of individual sensors with multiple gauges in one-cable-array design.
  • Fully customizable in number of gauges and their individual lengths.
Applications
  • Strain profile in concrete and metal structures Borehole deformation.

Application note

MSA-01 with 1mm outer diameter needs approximately 30N per 1000µε and since the strain transfer is generated directly from the anchor points, a wavelength shift of 1,2pm will result in 1 µε.
The relationship between the length change and wavelength shift is linear, however, we recommend using the equation with coefficients from the calibration sheet.
