Self-Heating Effect in RTD: Meaning, Cause, Formula and Practical Importance
Self-heating in an RTD occurs when the measuring current generates heat inside the sensing element, causing the RTD to indicate a slightly higher temperature than the actual medium. This article explains the cause, formula, example calculation, influencing factors, importance in calibration, and practical ways to reduce RTD self-heating error.
