TMT162 Technical data
Endress+Hauser 47
Measured error Pt100: 0.18 °F (0.1 °C)
Output measured error: 0.04 °F (0.02 °C) (0.02% of 212 °F)
Input temperature drift: 0.054 °F (0.03 °C)
Output temperature drift: 0.018 °F * 1.5 = 0.03 °F (0.015 °C)
Max. possible error (total of errors): 0.3 °F (0.165 °C)
Δϑ = deviation of ambient temperature from the reference operating condition.
Total measuring point error = max. possible measured error + temperature sensor error.
