HART - 4-20 mA analog composite signal - Sum of the modulated digital signal added to the analog signal of the measure.
  • The range of the analog signal for the measure is 16 mA, from 4 mA to 20 mA.
  • The range of the modulated signal for the datas is about 1 mA, ± 0.5 mA around the measurement value.
  • The modulated signal is added to the measure, consequently the mean value of the composite signal is the analog value of the measure.
