Convert RTD Reading
Converts an RTD voltage into a temperature value in degrees Celsius.
Ro
The RTD resistance at 0 degrees Celsius.
Default: 100 Ω
voltage
The voltage read from the RTD.
This input supports waveform and double-precision, floating-point data types.
Iex
The excitation current used with the RTD.
Default: 0.15 µA
A
A coefficient of the Callendar Van-Dusen equation that fits your RTD.
Default: 0.00390802 — Represents the coefficient for the European curve (also called the DIN 43760 standard).
B
A coefficient of the Callendar Van-Dusen equation that fits your RTD.
Default: -5.80195E-07 — Represents the coefficient for the European curve (also called the DIN 43760 standard).
temperature
The return temperature value in degrees Celsius.
This output returns a waveform or double-precision, floating-point data type depending on the data type of the voltage input.
