| -Accuracy |
See Documents section: "S Series Accuracies" |
| -Stability/Drift |
Long term drift for Advanced Performance pressure transmitters is < ±0.03% of URL/yr for 10 years. |
| -Ambient Temperature Effect (per 55ºC, 100ºF change) |
For biplanar AP/GP transmitters with Span Codes B, C, and D, the total effect for a 28°C (50°F) change within normal operating conditions is ±(0.04% URL + 0.050% Span); For biplanar AP/GP transmitters with Span Codes E and F, the total effect for a 28°C (50°F) change within normal operating conditions is ±(0.08% URL + 0.025% Span);For DP transmitters (all Span Codes), the total effect for a 28°C |
| -Static Pressure Zero Effect (DP only) (per 7Mpa, 1000 psi) |
The zero and span shift for a 1,000 psi (7 MPa) change in static pressure is described below. |
| -RFI Effect |
For AP and GP transmitters, the output error is less than 0.1% of calibrated span for radio frequencies in the range of 30 to 1000 MHz and field intensity of 30 V/m when the transmitter is properly installed with shielded conduit and grounding, and housing covers are in place (per IEC Std. 61000-4-3). For DP transmitters, the output error is less than 0.1% of span within standard accuracy turndown limits, for radio frequencies from 27 to 1000 MHz and field intensity of 30 V/m when the transmitter is properly installed with shielded conduit and grounding, and housing covers are in place (per IEC Std. 61000-4-3) |
| -Turndown Ratio |
400:1 |
| -Operating Temperature |
-29ºC to +82ºC (-20ºF to +185ºF) |
| -Storage Temperature |
-54ºC and +82ºC (-65ºF and +185ºF) |
| -Environmental Protection |
The transmitter’s enclosure has the weatherproof, dust-tight, and water-tight rating of IP66/67 as defined by IEC 60529, and provides the environmental and corrosion resistant protection rating of NEMA Type 4X. |
| -Output Signal |
For HART transmitters, 4 to 20 mA dc square root (for DP only) or 4 to 20 mA dc linear with digital HART communication. The output is software-selectable and remotely configurable from the HART Communicator, and locally configurable with the pushbuttons on the optional display. For FOUNDATION Fieldbus transmitters, square root (for DP only) or linear. The digital output is software-selectable and remotely configurable from a FOUNDATION Fieldbus host computer or a console equipped with a FOUNDATION Fieldbus Interface Module. It is also locally configurable with the pushbuttons on the optional display. |
