Accuracy
(Reference – Includes
combined effects of linearity,
hysteresis, and repeatability)
• Stated accuracy does not apply
for models with 2.9 inch
diameter remote seal
diaphragms.
• Accuracy includes residual error
after averaging successive
readings.
• For F
OUNDATION
Fieldbus use
Digital Mode specifications. For
HART use Analog Mode
specifications.
In Analog Mode:
±0.1% of calibrated span or upper range value (URV), whichever is
greater, terminal based.
For URV below reference point (30 psi), accuracy equals:

* 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.
** Transmitter URL limit or maximum seal pressure rating, whichever is lower.
*** Specification applies to transmitters with 2 seals only. Apply 1.5 times factor to temperature effect for capillary lengths greater than 10
feet.
