Introduction to RTD Sensor
RTD (Resistance Temperature Detector) sensors are a type of temperature sensor widely used in various industrial, scientific, and commercial applications. The principle behind RTDs is that the electrical resistance of a metal changes predictably with temperature. Commonly used metals in RTDs include platinum, nickel, and copper, with platinum being the most popular due to its high accuracy, stability, and wide temperature range. RTD sensors offer several advantages over other temperature sensing technologies, such as thermocouples. They provide more accurate and repeatable temperature measurements, are less prone to drift, and have a better linearity over a wide temperature range. RTD sensors are crucial in applications where precise temperature control and monitoring are required, such as in pharmaceutical manufacturing, food processing, HVAC systems, and aerospace engineering.
