Steinhart coefficients
The Steinhart–Hart equation is a model of the resistance of a semiconductor at different temperatures. The equation is $${\displaystyle {\frac {1}{T}}=A+B\ln R+C(\ln R)^{3},}$$where $${\displaystyle T}$$ is the temperature (in kelvins), $${\displaystyle R}$$ is the resistance at 查看更多內容 The equation is often used to derive a precise temperature of a thermistor, since it provides a closer approximation to actual temperature than simpler equations, and is useful over the entire working temperature range of the … 查看更多內容 The most general form of the equation can be derived from extending the B parameter equation to an infinite series: $${\displaystyle R=R_{0}e^{B\left({\frac {1}{T}}-{\frac {1}{T_{0}}}\right)}}$$ $${\displaystyle R_{0}}$$ is a reference (standard) … 查看更多內容 To find the resistance of a semiconductor at a given temperature, the inverse of the Steinhart–Hart equation must be used. See the 查看更多內容 The equation is named after John S. Steinhart and Stanley R. Hart who first published the relationship in 1968.
