Thermocouples, RTDs Sensors
Thermocouples and RTDs (Resistive Temperature Devices) are both devices commonly used for temperature measurement. The main difference between them is their respective sensing elements: a thermocouple uses two dissimilar metals, while a RTD uses a resistive wire element.
Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes. Thermocouples are also used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered appliances.
