Temperature Sensors - RTD (Resistance Temperature Detector)Temperature sensors are among the most important and widely used sensors in the industrial and research climate. Temperature sensors are used to measure the temperature of a variety of materials, from liquids to gases, metals to alloys, and organic materials. RTDs (resistance temperature detectors) are a class of temperature sensors that measure temperatures using electrical resistance. RTD\'s, as they are commonly known, are often used because of their accuracy, repeatability, and linearity when compared to other temperature sensors. RTDs, or resistance temperature detectors, measure temperature by determining the amount of thermal energy which is required to alter the electrical resistance of a material. RTDs are designed so that when a change in temperature is applied, the resistance of the device changes in a predictable, linear manner. The amount of resistance change is directly proportional to the temperature change. In essence, a resistance temperature detector is a resistor that changes resistance when the temperature of its surroundings is altered. RTDs come in a variety of configurations and materials. Most RTDs are made of Platinum due to its stability and low temperature drift. Other materials can also be used, including Nickel, Copper, and Palladium. RTDs come in a variety of shapes and sizes as well, ranging from minuscule 6mm point sensors to large U-shaped wire elements that span several feet.Although RTD’s range in shape and size, they all share a common basic principle: they measure the resistance of a material which changes proportionally with temperature. RTDs can cover a range of temperatures from –270°C to over 850°C with a typical accuracy of ± 0.1°C. RTDs are often used in industrial settings where accuracy and repeatability is crucial. They are also popular in hazardous environments due to their ability to withstand extreme temperatures, as well as in scientific and research applications for their repeatability. One of the most common applications of an RTD is in an immersion temperature gauge, which consists of a 20K ohm RTD placed in direct contact with the material being measured.The 32207399 application field and working principle of RTDs can be summarized by stating that it is a type of temperature sensor which measures the electrical resistance of a material which changes proportionally with temperature. RTDs allow for accurate and repeatable measurements of temperature over a range of temperatures from -270°C to over 850°C with a typical accuracy of ± 0.1°C. RTDs are most often used in industrial and hazardous environments, as well as scientific and research environments due to their accuracy and repeatability. The most common application for an RTD is in an immersion temperature gauge.
