Introduction

Resistance Temperature Detector (RTD) is a temperature sensor that measures temperature by detecting a change in its resistance. RTDs, also known as temperature probes, are among the most precise temperature measurement tools available. The RTD measures temperature by converting the changes in resistance directly to temperature readings with the help of a precision current source. The 32207594-4K RTDs are some of the most widely used and reliable RTDs standards available.

Principle of Operation

An RTD relies on its inherent property of resistance change when subjected to a change in temperature. RTDs are typically constructed of metals such as copper, nickel, platinum or stainless steel. A resistance element, such as a coil, is wound in the metal and the measurement device supplies a constant current which runs through the element. As the temperature of the coil increases or decreases, its resistance changes in direct proportion. A change of 0.006 ohms is typical for every degree Celsius change in temperature.The most important aspect of the RTD operation is to maintain a constant current source. This is critical because it aids in maintaining the resistance-temperature relationship. By supplying a constant current, the output signal from the RTD element is reliably and precisely proportional to the temperature.
