RTDPTCPt100

A temperature sensor is a device that detects and measures heat and cold by converting the data into an electrical signal. RTDs (Resistance Temperature Detectors) are temperature sensors that use a resistor whose value changes as the temperature changes. Typically, RTD probes consist of a thin coiled wire wrapped around a ceramic or glass core, in order to protect them due to their fragility. The most popular RTD is the Pt100, which is known for its accuracy, stability and repeatability. Pt100s are also relatively immune to electrical noise, making them suitable for measuring temperature in industrial environments, such as motors, generators and high voltage equipment. These sensors are made of platinum (Pt) and have a resistance value of 100 ohms at 0°C. There is also the Pt1000 sensor, which has a resistance value of 1000 ohm at 0°C. Both Pt100 and Pt1000 can be used interchangeably, depending on the instrument used and the specifics of the application. In some cases, Pt1000 may offer greater accuracy. Resistance temperature detectors can be classified according to the type of sensing element used. Some use thin film elements, while others use wound wires. Each type is better suited to certain environments and applications. PT100 resistance thermometers, commonly called "PT100 probes", are thermosensitive elements known for their sensitivity, accuracy and reliability. They come in various shapes, sizes and materials and are commonly used in applications with maximum temperatures up to 650°C (1200°F).
