PERFORMANCE
SPECIFICATIONS
For zero based spans, reference conditions, silicone fill fluid, SST materials,
digital trim values range points. Applies to 4-20 mA HART output only unless
otherwise noted.
Conformance To
Specification (±3
(Sigma))
Technology leadership, advanced manufacturing techniques, and statistical
process control ensure specification conformance to at least ±3.
Reference Accuracy
2088
±0.10% of calibrated span. Includes combined effects of linearity,
hysteresis, and repeatability.
+/-0.075% of calibrated span (high accuracy option P8)
2090
+/- 0.20% of calibrated span. Includes combined effects of linearity,
hysteresis, and repeatability.
+/- 0.10% of calibrated span (high accuracy option P8)
Ambient Temperature Effect
2088
Expressed as a total effect per 50 °F (28 °C). Total effect includes zero and
span effects.
+/- (0.15% URL + 0.15% of span) from -40 to 185 °F (-40 to 85 °C)
2090
Expressed as a total effect per 100 °F (56 °C).
± (0.3% URL + 0.3% of span) from –40 to 185 °F (–40 to 85 °C).
Stability
±0.10% of upper range limit for 12 months.
