Steinhart-Hart equation
From Wikipedia, the free encyclopedia
The Steinhart-Hart equation is a model of the resistivity of a semiconductor at different temperatures. The equation is:
where:
- T is the temperature (in kelvins)
- ρ is the resistivity (In Ohms)
- A, B, C, and D are the Steinhart-Hart coefficients which vary depending on the type and model of thermistor and the temperature range of interest. The C coefficient is frequently neglected because it is typically much smaller than the other coefficients.
[edit] Developers of the Equation
The equation is named after John S. Steinhart and Stanley R. Hart who first published the relationship in 1968[1]. Professor Steinhart (1929-2003), a fellow of the American Geophysical Union and of the American Association for the Advancement of Science, was a member of the faculty of University of Wisconsin-Madison from 1969-1991[1]. Dr. Hart, a Senior Scientist at Woods Hole Oceanographic Institution since 1989 and fellow of the Geological Society of America, the American Geophysical Union, the Geochemical Society and the European Association of Geochemistry, [2] was associated with Professor Steinhart at the Carnegie Institution of Washington when the equation was developed.
