Accuracy and Stability
Differential and absolute pressure
accuracy
±0.05% of span (for spans ≥10% of URL)
±(0.005) x (URL/span)% of span (spans <10% URL)3
Process temperature accuracy (°F/°C) ±0.5 (0.28), not including RTD uncertainties
Stability <±0.05% of URL per year over five years
Static pressure effect ZERO Shift ±0.05% of URL, SPAN Shift ±0.1% of reading for 1000 psi (7 MPa)
Ambient temperature effect Total effect for a 100°F (55°C) change for absolute and differential pressure is:
