Convert thermistor resistance to temperature
Webfunction is first used to convert the thermistor resistance to temperature. The zone box temperature is then used as the reference junction temperature for the Jtemp, Ktemp or Ttemp function. Suppose the resistance of a YSI 44006 thermistor in the zone box is 11240Ω, and that a J-type thermocouple with a reference junction in the zone box has WebJun 28, 2024 · Where: T 1 is the first temperature point in Kelvin; T 2 is the second temperature point in Kelvin; R 1 is the thermistors resistance at …

Web4.1 Conversion from resistance to temperature. Based on a measured resistance value of an NTC thermistor the extended Steinhart-Hart equations allows a simple calculation of the temperature. 1 / T = a 0 + a 1 · ln r + a 2 · (ln r) 2 + a 3 · (ln r) 3. Here r is the resistance in Ω and T the absolute temperature in K (K
