Resistance thermometers are temperature sensors that operate on the principle of variation of electrical resistance of a metal as a function of temperature.
Platinum resistance thermometer which has an ohmic resistance of 100 ohmn at 0°C is known as PT100 or RTD. Their scale of work is from -200 to 600ºC. The error limits of the PT-100 are referred to DIN EN 60751 standards. Its use in the industry provides accuracy, stability and sensitivity.
In the temperature measurement with 3-wire resistance thermometer the distance can be about 30 m.
