Temperature measurement is an ubiquitous primary element of almost every fluid process control operation, as well as a host of other industrial applications. Selecting and properly applying a temperature sensing technology is key to effective process measurement. Of the two common technologies, RTD and thermocouple, each has advantages under a certain set of operating conditions, and it is useful to be familiar with the basics of how they work and how they should be applied.
Pyromation, a long standing manufacturer of temperature measurement devices for industrial and scientific applications, provides us with a useful white paper detailing thermocouple and RTD operation, as well as the strengths and weaknesses of each in application.
