For example, the temperature of a 3D-printer’s hot-end is typically measured with an NTC thermistor, generally with a rated ambient temperature (25ºC/77ºF) resistance of 100kΩ. When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If the thermistor is being used to measure the temperature of the environment, this electrical heating may introduce a significant error (an observer effect) if a correction is not made. Alternatively, this effect itself can be exploited. It can, for example, make a sensitive air-flow device employed in a sailplane rate-of-climb instrument, th… sharon lee smith california
