Resistance thermometers use the change in resistance of a metal wire with temperature to convert the temperature to be detected into a measurable signal. The material offering the best sensitivity, linearity and stability for this purpose is platinum. Resistance thermometers are identified by the abbreviation of the metal of which the sensing element is made, followed by the resistance value of the sensing element at a temperature of 0 °C. Examples of the most common resistance thermometers are Pt25, Pt100 and Pt1000.
Our laboratory can calibrate these probes by taking readings resistance and by calculating the parameters of the characteristic curve of the probe, as well as supplying the resistance-temperature conversion tabulation in full.
