Thermocouple vs RTD: Which Temperature Sensor Is Better?
Temperature measurement is essential in many industrial and commercial applications. Two of the most widely used temperature sensors are thermocouples and RTD sensors (Resistance Temperature Detectors). Engineers and buyers often ask the same question: Thermocouple vs RTD — which temperature sensor should you choose? Understanding the difference between these two technologies helps ensure accurate temperature measurement, longer sensor life, and better performance for your application. What Is a Thermocouple? A thermocouple is a temperature sensor made by joining two different metal wires together. When the junction of these two metals is exposed to heat, a small voltage is generated. This
