How To Select And Use The Right Temperature Sensor

people usually ask the question “OK, so how do I determine which sensor to use in my application?” . This paper is intended to answer that question. After a brief review of how (RTD) and thermocouples are constructed and used to measure temperature, we will discuss what differentiates these sensors from one another. We will discuss the topics of temperature range, tolerance, accuracy, interchangeability and relative strengths and weaknesses for each type. After reviewing these topics you will have a better understanding as to when each type of sensor should be used and why.
