TEMPERATURE CONTROL

  • Resistance of platinum resistance sensor converted to digital values
  • Internally stored mathematical polynomials convert digital values to temperature
  • Calibrated digitized temperature compared to user-set temperature
  • Four-point calibration provides greater accuracy
