Accuracy
Reference conditions
(All error data refer always refer to the set
span)
Error in measurement and fixed-point setting
(including hysteresis and repeatability)
• Linear characteristic
- r ≤ 10
- 10 < r ≤ 30
- 30 < r ≤ 100
Long-term drift (temperature change ± 30 °C
(± 54 °F))
Influence of ambient temperature
• at -10 ... +60 °C (14 ... 140 °F)
• at -40 ... -10 °C and +60 ... +85 °C
(-40 ... +14 °F and 140 ... 185 °F)
Influence of medium temperature
• Temperature difference between medium
temperature and ambient temperature
Influence of mounting position
