網頁2024年10月21日 · I looked up the data table for a thermistor I purchased and noticed it uses an 'extended' Steinhart-Hart equation. I'd like to understand the difference between … 網頁The equation is: 1 T = A + B ln ( R) + C ( ln ( R)) 3. where: T is the temperature (in kelvins) R is the resistance at T (in ohms) A, B, and C are the Steinhart–Hart coefficients which vary depending on the type and model of thermistor and the temperature range of interest. (The most general form of the applied equation contains a ( ln.

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 Application Note, "A, B, C Coefficients for … 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.
