Resistance behavior

Resistance thermometers can be designed for temperatures between −328 and 932 °F. Outside of that range, resistance becomes non-linear or doesn’t depend on temperature. Most resistance thermometers are designed to work immersed in the environment or liquid that they measure; later, Samuel Pierpont Langley showed, with a similar design, the ability to determine a temperature at a distance.

Carl Wilhelm Siemens, without a criminal intent, also became known as Sir Charles William Siemens.
