HART PROTOCOL MODULATED ANALOGICAL SIGNAL

• The range of the analogical signal for the measure is 16 mA, from 4 mA to 20 mA.
• The range of the modulated signal for the data 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 analogical value of the measure.
