What is an RTD?
An RTD (Resistance Temperature Detector) is a temperature sensor that measures temperature by detecting changes in electrical resistance of a metal element, usually platinum, nickel, or copper. It generally consists of a sensing element, lead wires, protective sheath, and housing, which can be made of stainless steel or armored casing. RTDs are widely used in industrial automation, chemical, food processing, pharmaceutical, and HVAC systems.
