EXPLANATIONS OF TERMS ■ ACCURACY This transmitter’s accuracy is theoretically defined as the addition of A/D and D/A conversion errors:
The A/D conversion error means that measured as HART signal which is A/D converted from the analog input signal. The D/A conversion error of this transmitter is relatively very small so that it does not really affect the unit’s overall performance. The “Accuracies” given in Table 1 therefore equals the A/D conversion error. The temperature drift (coefficient) or the cold junction compensation error is not included in the “Accuracy.” ■ CALCULATION EXAMPLES OF OVERALL ACCURACY IN % • DC Voltage 1) 0 – 200 mV Absolute value accuracy (Table 1): 40 μV 40 μV ÷ 200000 μV × 100 = 0.02 % < 0.1 % ➠ Overall accuracy = ±0.1% of span 2) 0 – 4 mV Absolute value accuracy (Table 1): 10 μV 10 μV ÷ 4000 μV × 100 = 0.25 % > 0.1% ➠ Overall accuracy = ±0.25 % of span • Thermocouple 1) K thermocouple, 0 – 1000°C Absolute value accuracy (Table 1): 0.25°C 0.1% × 1000°C = 1°C > 0.25°C CJC error (0.5°C) added: 1 + 0.5 = 1.5°C 1.5°C ÷ 1000°C × 100 = 0.15 % ➠ Overall accuracy including CJC error = ±0.15 % of span 2) K thermocouple, 50 – 150°C Absolute value accuracy (Table 1): 0.25°C 0.1 % × (150 – 50)°C = 0.1°C < 0.25°C CJC error (0.5°C) added: 0.25 + 0.5 = 0.75°C 0.75°C ÷ (150 – 50)°C × 100 = 0.75 % ➠ Overall accuracy including CJC error = ±0.75 % of span • RTD 1) Pt 100, -200 – 800°C Absolute value accuracy (Table 1): 0.15°C 0.15°C ÷ (800 – -200)°C × 100 = 0.015 % < 0.1 % ➠ Overall accuracy = ±0.1 % of span 2) Pt 100, 0 – 100°C Absolute value accuracy (Table 1): 0.15°C 0.15°C ÷ 100°C × 100 = 0.15 % > 0.1 % ➠ Overall accuracy = ±0.15 % of span
