dc.descriptionSummary: Thermistors used as temperature sensing devices develop internal heat by the passage of electrical current during measurements. A theoretical analysis of effect of internal heat generation is applied to one type of thermistor. Calculations of steady-state temperature rise over the ambient indicate that the magnitude of error for the thermistor located in soil, ice, light snow, medium snow, and heavy snow ranged from 6.5 x 10^-5 to 246 x 10^-5 °F, while the magnitude of error for the thermistor located in air ranged from 712 x 10^-5 to 1425 x 10^-5 °F, depending on the heat transfer coefficient. Calculations indicate that in most cases errors due to internal heating may be disregarded for ground and air temperature measurements.-
