WebRTD generally operates in the range between -200 to 600° C. In contrast, a thermocouple offers even wider operating range than RTD i.e., usually -200 to 2000° C. Thus, thermocouple suits a variety of applications. Thermocouples offer a response time of 0.1 to 10s which is better than the response time of RTDs ranging between 1 to 50s. WebA thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wire legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a temperature dependant voltage is produced.
