Quality Statement The SWS-03 sensor is compliant with IEC 61757-1-1:2020 and IEC 61757:2026. All sensors are 100% tested and calibrated at SYLEX. The sensor is manufactured according to ISO 9001:2008 and ISO 14001:2004.

Notes:

  • 1) Accuracy is established for each sensor under laboratory conditions, and it includes hysteresis, non-linearity, and repeatability of the sensor. The guaranteed value is determined based on the largest absolute error found in this sample. The typical value is determined based on the average absolute error found in this sample.
  • 2) Precision is established on a batch basis and includes hysteresis, non-linearity, repeatability, and reproducibility of the sensor. The guaranteed value is determined based on the largest absolute error found in this sample. The typical value is determined based on the average absolute error found in this sample.
  • 3) FS: full-scale measurement range.
  • 4) The temperature range can be extended for operation from -35°C to +70°C.
  • 5) The operational strain range can be extended for ±2000μɛ.
  • 6) See the product drawing for further dimensional details.
  • 7) Cable length is extendable upon request.
  • 8) Other connector types available upon request.
