Resistance Thermometer : Temperature Coefficient of Resistance Calculator
Posted by Dinesh onCalculate 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
