RTD Tables
Platinum RTDs to IEC 60751, the 0.00385 curve. Resistance against temperature by the Callendar-Van Dusen equation, so the table is generated, not looked up and rounded. Convert a single reading either way, or build a table at any interval.
Guided setup
Tell me the sensor, the direction, and your reading. The wizard runs the exact same IEC 60751 math as the form, and it can build a resistance table over any range.
The wizard only asks questions and runs the calculator. Every number comes from the deterministic engine, not the AI.

If the numbers here do not match what the loop is doing, the problem is usually the installation, the ranging, or the process itself rather than the device. Describe the symptom and a specialist answers by email, at no charge.
