Accuracy (Reference – Includes
combined effects of linearity,
hysteresis, and repeatability)
•
Accuracy includes residual error
after averaging successive
readings.
• For FOUNDATION Fieldbus use
Digital Mode specifications. For
HART use Analog Mode
specifications.
In Analog Mode:
±0.15% of calibrated span or upper range value (URV), whichever is
greater.
For URV below reference point (300 psi), accuracy equals:
±0.10 + 0.05

* Performance specifications are based on reference conditions of 25°C (77°F), zero (0) static pressure, 10 to 55% RH, and
316L Stainless Steel barrier diaphragm.
