Calculate temperature coefficient of resistance using simple resistance thermometer calculator online.
Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes.
Formula:
where,
R0 = resistance of the sensor at 0 °C
R100 = resistance of the sensor at 100 °C
α = temperature coefficient of resistance
R0 = resistance of the sensor at 0 °C
R100 = resistance of the sensor at 100 °C
α = temperature coefficient of resistance
