RTD TEMPERATURE VS RESISTANCE TABLES
The tables in the links below display the relationship between temperature and the electrical resistance of RTDs. The tables are in 1 degree increments. Linear interpolation can be used for “in-between” temperatures. The actual resistance/temperature mathematical functions can be found in Minco’s whitepaper, “Resistance Thermometry”.
