SDP31 Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for SDP31 is -20°C to 60°C. However, it can operate up to 85°C with reduced accuracy and lifetime.
  • The SDP31 is factory-calibrated and does not require additional calibration. However, it's recommended to perform a zero-point calibration in the application to compensate for any offset errors.
  • The SDP31 can measure differential pressures up to 350 mbar (35 kPa) with an accuracy of ±1.5% of the full scale.
  • Yes, the SDP31 is designed to operate in humid environments and can withstand relative humidity up to 90% RH. However, it's recommended to use a protective coating or enclosure to prevent condensation and corrosion.
  • The response time of SDP31 is typically around 1 ms, making it suitable for fast-changing pressure applications.
