1)
Preassembled Pt100: Class A (maximum MES: 0.15 + 0.002*|t| °C)
2)
Error calculation:
• Probable overall error = Ö(MES2 + AET2 + LTD2 + ATE2)
• Maximum overall error = MES + AET + LTD + ATE
• |t|: Absolute total of the measured temperature
• MES: Measuring error of the sensor
• AET: Measuring error of the transmitter (A/D conversion)
• LTD: Long-term drift
• ATE: Drift via ambient temperature
