MS-03 Mountable strain sensor

Type: Short-gauge strain sensors

Application: Concrete or grout embeddable, surface mountable

Installation method: Mounting brackets – weldable, screwable

Pre-strain setup: At installation

Temperature compensation: Through external temperature sensor

  • MS-03 is an improved sensor, developed to replace our MS-01 sensor
  • Short gauge strain sensor with a 90-110mm measuring base (gauge length).
  • MS-03 is capable of measuring length changes in µɛ or µm between its anchoring points.
  • Possible pre-strain setup during installation up to ±5000µɛ.
  • MS-03 can be connected in a series configuration.
  • Various anchoring designs
  • Embeddable into concrete/grout
  • Strain monitoring
  • Rebar strain or force monitoring
  • Wall-tie monitoring

Quality Statement MS-03 sensor is compliant with IEC 61757:2018 and IEC 61757-1-1:2020. All sensors are 100% tested and calibrated at SYLEX. Sensor is manufactured according to ISO 9001:2008 and ISO 14001:2004


  • 1) Calibrated in µm on demand
  • 2) Accuracy is established for each individual sensor under laboratory conditions and it includes hysteresis, non-linearity and repeatability of the sensor.
  • 3) Precision is established on a batch basis and it includes hysteresis, non-linearity, repeatability and reproducibility of the sensor.
  • 4) FS: full scale range
  • 5) For further dimensions details see the product drawing
  • 6) Cable length is extendable on request
  • 7) Other connector types available on request
