¹ - Time required to reach 63% of a temperature step.

² - Includes reproducibility (sensor/module exchange), repeatability and hysteresis, non-linearity, scale error, offset error, conditioner temperature compensation error

  • Temperature:

Accuracy of ±0.25°C can be achieved using the 25°C to 45°C calibration.

Accuracy of ±0.40°C can be achieved using the −10°C to 120°C calibration.

  • Pressure:

Accuracy at room temperature.

³ - SCAI is an SCA connector with smart chip communicating calibration data to signal conditioner module.
