RTDs(Resistance Temperature Devices)

RTDs, or resistance temperature detectors, are temperature sensors that measure temperature by determining the resistance of a material as its temperature changes. RTDs are commonly made of materials such as copper, nickel, or platinum, which have a predictable change in resistance as their temperature changes.

RTDs are widely used in a variety of applications, including industrial process control, HVAC systems, and laboratory equipment. They are known for their high accuracy and stability, making them a popular choice for temperature measurement in many industries.

There are two main types of RTDs: wire-wound RTDs and thin-film RTDs. Wire-wound RTDs are made by winding a wire, typically made of copper or nickel, around a ceramic or glass core. Thin-film RTDs are made by depositing a thin film of a conductive material, such as platinum, onto a substrate.

RTDs are used in a variety of settings, including high-temperature environments, as they can operate at high temperatures without degradation. They are also resistant to vibration and shock, making them a good choice for use in industrial applications.

Overall, RTDs are a reliable and accurate means of measuring temperature in a variety of settings.
