Resistance Temperature Detector (RTD)

A Resistance Temperature Detector (RTD) is a temperature sensor that measures temperature by correlating the
resistance of the sensor element with temperature. RTDs typically use pure platinum as the sensing element due to
its stable and repeatable resistance-temperature relationship.

  • Working Principle: The resistance of the RTD changes with temperature; specifically, it increases as the
    temperature rises. This change in resistance can be measured and converted into a temperature reading.
  • Applications: Widely used in industrial, HVAC, and laboratory applications for precise temperature
    measurement and control.
RTDs are favored in many applications due to their sensitivity, accuracy, and ability to perform well over time and across varying environmental conditions.

When selecting an RTD, it’s essential to consider the specific requirements of your application,
including temperature range, accuracy, and environmental conditions
