網頁Steinhart-Hart Temperature Calculator. Thermistor resistance is related to temperature in degrees Kelvin by the following formula: 1/T= A + B*ln (R/Rt) + C*ln (R/Rt) 2 + D*ln (R/Rt) 3. In the standard Steinhart-Hart equation the C parameter is set to zero. However, some manufacturers use all 4 coefficients. roof hawk ai phone number網頁The Steinhart-Hart coefficients A, B, and C can be obtained by solving the above matrix equation: A = 1.1384 ×10-3, B=2.3245 ×10-4, C=9.489 ×10-8. The LDC501 uses these … roof hawk ai網頁Equation (8) has been a more widely used form of the equation since the solutions for the three coefficients are more easily attained with three resistance/temperature data points.
