App id: INST-23. Reference version 1.0.

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

R(T) = R0 (1 + A T + B T²)  [T ≥ 0 °C]

Inputs

NameUnit
TemperatureC

Outputs

NameUnit
Resistance (hero result)ohm

Diagnose

This tool does not attach diagnose observations.

Assumptions

  • Leave R0 blank for Pt100.

Provenance

  • Same coefficients as INST-22.
