Technical specifications (continued)

Industrial Wireless Communication

WirelessHART

SITRANS TF280, WirelessHART

Preassembled Pt100: Class A (maximum MES: 0.15 + 0.002*|t| °C)

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
