Use this PT100 Calculator to calculate temperature and resistance values from the standard PT100 curves. The calculator will produce a temperature value from an entered resistance or calculate resistance and thermometer sensitivity values from an entered temperature.
Use this PT100 Table Generator to generate a custom PT100, PT500, or PT1000 resistance table in Celsius, Fahrenheit, or Kelvin, by PT-385 or PT-392 thermometer type in any increment that you can download as a CSV and print.
Platinum Resistance Thermometry: Resistance vs Temperature relationship, tolerances, connection schematics, measuring circuits. Resistance vs Temperature Relationship Over The Range -200°C to +850°C. Tolerance values for 100 ohm elements,
A Pt100 is a platinum resistance thermometer (Pt=Platinum) with a defined resistance value of 100 Ω at a temperature of 0 °C. The resistance of a Pt100 increases with increasing temperature (positive temperature coefficient).
