Fundamentals of Instrumentation, Process Control - EIT

Self-heating: Another consequence of current excitation of the RTD is the possible effect that internal heating of the device may have on the accuracy of the actual temperature measurements being made. The degree of self-heating depends on the medium in which the RTD is being used, and is typically specified as the rise in temperature for each
