WEBThe wire or resistance is typically platinum but may also be made from nickel or copper. The PT100 is a common RTD constructed from platinum with a resistance of 100 Ω at 0°C.
Taking Temperature Measurements with RTDs: How-To Guide
WEBMay 15, 2024 · Resistance-Temperature Curve for a 100 Ω Platinum RTD, a = 0.00385. This relationship appears relatively linear, but curve fitting is often the most accurate way to make an accurate RTD measurement. The most common RTD is the platinum thin-film with an a of 0.385%/°C and is specified per DIN EN 60751.
WEBHow to calibrate an RTD or Platinum Resistance Thermometer (PRT) Application Note From the Fluke Digital Library @ www.fluke.com/library Introduction There are two types of calibrations applicable to PRTs—characterization and tolerance testing. The type of calibration to perform is determined by the way in which the UUT is
Driving RTD Temperature Sensors Appropriately | DigiKey
WEBJul 7, 2020 · A widely used choice for a temperature sensor is the resistance temperature detector (RTD), a precision metal element usually made of pure or nearly pure platinum. A platinum-based sensor has a fully detailed, repeatable, and characterized resistance-versus-temperature transfer function, so RTDs are widely used in scientific and instrumentation ...
Basics of Resistance Temperature Detectors (RTDs)
WEBThe resistive material may be platinum, copper or nickel with the most common by far being platinum because of its high accuracy, excellent repeatability, and exceptional linearity over a wide range and it exhibits a large resistance change per degree of temperature change.
