Calculadora de Temperatura RTD (PT100/PT1000)
Convierte resistencia a temperatura para sensores RTD PT100 y PT1000 según IEC 60751.
Fórmula
Cómo Funciona
Resistance Temperature Detectors (RTDs) are precision temperature sensors that utilize the predictable relationship between electrical resistance and temperature in pure metals. The PT100 and PT1000 are standardized platinum resistance thermometers where the '100' or '1000' represents the resistance at 0°C, and the fundamental principle is that the electrical resistance of platinum increases linearly with temperature.
Ejemplo Resuelto
Problem: Calculate the temperature for a PT100 sensor with a measured resistance of 138.5Ω Solution: 1. R0 = 100Ω, α = 0.003851°C⁻¹ 2. T = (138.5 - 100) / (100 * 0.003851) 3. T = 38.5 / (100 * 0.003851) 4. T = 100°C
