What this tool does
Callendar–Van Dusen resistance and temperature for IEC 60751 RTDs. This page says what the tool is for, in plain language. The working formula stays on the signed-in tool.
When to use it
Open RTD Pt100 / Pt1000 when this is the job: Callendar–Van Dusen resistance and temperature for IEC 60751 RTDs. That is usually a sensor check, a cold-junction question, or a reading that does not match the gauge.
Step-by-step
- Open RTD Pt100 / Pt1000 from the tool list.
- Fill Sensor, Direction, Value from the instrument, the drawing, or the job record. Use the unit shown beside each field.
- Run Calculate when that control is on the page, then read every result row and any warning.
- Check the result against the site procedure and the manufacturer data before you change a range, a wire, a setpoint, or a weight.
- This help page is public. Opening the tool still requires a Pro session.
Inputs
- Sensor
- The resistance thermometer or thermocouple type named on the head.
- Direction
- Which way the conversion runs, from the engineering value to the signal or the other way.
- Value
- The number you are converting. Read the unit the screen is asking for.
Results
- Result
- The reported value for RTD Pt100 / Pt1000. Use the unit printed on that row.
- Warnings
- A warning means an entry is incomplete or outside what this tool will stand behind. Recheck the inputs and the site procedure.
Common mistakes
- Picking the wrong sensor type, or leaving the cold junction at a temperature the terminal is not at.
- Reading resistance or millivolts as if they were already a temperature.
- Using a tolerance class that is not the class stamped on the sensor.
- Do not treat a result from RTD Pt100 / Pt1000 as a substitute for the site procedure or the manufacturer data.
