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 |
