Thermocouples and RTDs
Thermocouples and RTDs (Resistance Temperature Detectors) are types of temperature sensors widely used for temperature measurement in industrial processes, HVAC systems, or scientific research. Thermocouples consist of two dissimilar metal wires, generating a voltage proportional to the temperature difference between the sensing junction and the reference junction. RTDs, on the other hand, are temperature sensors with a defined resistance that changes with temperature. Thermocouples and RTDs offer accuracy, reliability, and compatibility with different temperature ranges and environmental conditions, providing precise temperature measurement in diverse applications.
