Measurement range,
turndown ratio, zero
suppression, and zero
elevation
(continued)
Reference accuracy -
per IEC 770 and SAMA
PMC 31.1
All reference accuracy
values are for transmit-
ters with zero based
spans, silicone oil fill,
and Hastelloy C-276
isolating diaphragms at
a reference tempera-
ture of 25°C (77°F).
The reference accuracy includes the effects of linearity, hysteresis, repeatability,
and deadband. The value listed may vary depending on the URL and calibrated
span of the particular transmitter. To determine the accuracy of a transmitter:
RA or
whichever is greater, where
RA = reference accuracy at
1:1 TDR and CF = compensation factor due to TDR.
Stability per 12-month
period
±0.1% of URL (±0.2% of URL for Type PTSDDA pressure transmitter) at reference
