 ## Introduction
 RTDs (Resistance Temperature Detectors) and Thermocouples are used for temperature measurement in various industrial fields. **RTDs** are sensors that change resistance in response to temperature variation. They are used regularly in industries that require precise temperature measurements, such as food processing and pharmaceuticals.

 On the other hand, **Thermocouples** are transducers that provide a voltage proportional to the temperature difference between two junctions. They are widely used in industrial applications such as HVAC systems, diesel engines, and power plants.
