How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
Span = URV − LRV; EU/mA = Span / 16Inputs
| Name | Unit |
|---|---|
| Lower range (LRV) | psi |
| Upper range (URV) | psi |
Outputs
| Name | Unit |
|---|---|
| Span (hero result) | psi |
| Midpoint | psi |
| EU per mA | psi |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Assumes a 4–20 mA (16 mA) live span.
Provenance
- EU/mA is span/16 displayed in the engineering pressure unit.
